Introduction 110 This document defines a YANG data model for IS-IS routing protocol. 112 The data model covers configuration of an IS-IS routing protocol 113 instance as well as operational states. 115 1.1. Tree diagram 117 A simplified graphical representation of the data model is presented 118 in Section 2. 120 The meaning of the symbols in these diagrams is as follows: 122 o Brackets "[" and "]" enclose list keys. 124 o Curly braces "{" and "}" contain names of optional features that 125 make the corresponding node conditional. 127 o Abbreviations before data node names: "rw" means configuration 128 (read-write), and "ro" state data (read-only). 130 o Symbols after data node names: "?" means an optional node and "*" 131 denotes a "list" or "leaf-list". 133 o Parentheses enclose choice and case nodes, and case nodes are also 134 marked with a colon (":"). 136 o Ellipsis ("...") stands for contents of subtrees that are not 137 shown. 139 2. Design of the Data Model 141 The IS-IS YANG module is divided in two main "isis" containers that 142 are augmenting the "control-plane-protocol" lists in ietf-routing 143 module with specific IS-IS parameters. 145 One container contains the writable parameters, while the other 146 contains the operational states. 148 The figure below describes the overall structure of the isis YANG 149 module: 151 module: ietf-isis 152 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 153 +--ro metric?

IS-IS Configuration 448 The IS-IS configuration container is divided in: 450 o Global parameters. 452 o Per interface configuration (see Section 2.4). 454 Additional modules may be created this to support any additional 455 parameters. These modules should augment the ietf-isis module. 457 The model implements features, so some of the configuration statement 458 becomes optional. As an example, the ability to control the 459 administrative state of a particular IS-IS instance is optional. By 460 advertising the feature "admin-control", a device communicates to the 461 client that it supports the ability to shutdown a particular IS-IS 462 instance. 464 The global configuration contains usual IS-IS parameters such as lsp- 465 mtu, lsp-lifetime, lsp-refresh, default-metric ... 467 2.2. Multitopology Parameters 469 The model supports multitopology (MT) IS-IS as defined in [RFC5120]. 471 The "topologies" container is used to enable support of MT 472 extensions. 474 The "name" used in the topology list should refer to an existing RIB 475 of the device. 477 Some specific parameters could be defined on a per topology basis 478 both at global level and at interface level: for example, an 479 interface metric can be defined per topology. 481 Multiple address families (like IPv4 or IPv6) can also be activated 482 within the default topology. This can be achieved using the "afs" 483 container (requiring "nlpid-control" feature to be advertised). 485 2.3. Per-Level Parameters 487 Some parameters support a per level configuration. In this case, the 488 parameter is modeled as a container with three configuration 489 locations: 491 o top level container: corresponds to level-1-2, so the 492 configuration applies to both levels. 494 o level-1 container: corresponds to level-1 specific parameters. 496 o level-2 container: corresponds to level-2 specific parameters. 498 +--rw priority 499 | +--rw value? uint8 500 | +--rw level-1 501 | | +--rw value? uint8 502 | +--rw level-2 503 | +--rw value? uint8 505 Example: 507 508 250 509 510 100 511 512 513 200 514 515 517 An implementation SHOULD prefer a level specific parameter over a 518 level-all parameter. As example, if the priority is 100 for the 519 level-1, 200 for the level-2 and 250 for the top level configuration, 520 the implementation should use 100 for the level-1 and 200 for the 521 level-2. 523 Some parameters like "overload bit" and "route preference" are not 524 modeled to support a per level configuration. If an implementation 525 supports per level configuration for such parameter, this 526 implementation SHOULD augment the current model by adding both 527 level-1 and level-2 containers and SHOULD reuse existing 528 configuration groupings. 530 Example of augmentation: 532 augment "/rt:routing/" + 533 "rt:control-plane-protocols/rt:control-plane-protocol"+ 534 "/isis:isis/isis:overload" { 535 when "rt:type = 'isis:isis'" { 536 description 537 "This augment IS-IS routing protocol when used"; 538 } 539 description 540 "This augments IS-IS overload configuration 541 with per level configuration."; 543 container level-1 { 544 uses isis:overload-global-cfg; 545 description 546 "Level 1 configuration."; 547 } 548 container level-2 { 549 uses isis:overload-global-cfg; 550 description 551 "Level 2 configuration."; 552 } 554 } 556 If an implementation does not support per level configuration for a 557 parameter modeled with per level configuration, the implementation 558 SHOULD advertise a deviation to announce the non support of the 559 level-1 and level-2 containers. 561 Finally, if an implementation supports per level configuration but 562 does not support the level-1-2 configuration, it SHOULD also 563 advertise a deviation. 565 2.4. Per-Interface Parameters 567 The per-interface section of the IS-IS instance describes the 568 interface specific parameters. 570 The interface is a reference to an interface defined in the "ietf- 571 interfaces" YANG model. 573 Each interface has some interface-specific parameters that may have a 574 different per level value as described in previous section. An 575 interface-specific parameter always override an IS-IS global 576 parameter. 578 Some parameters like hello-padding are defined as containers to allow 579 easy extension by vendor specific modules. 581 +--rw interfaces 582 +--rw interface* [name] 583 +--rw name if:interface-ref 584 +--rw level-type? level 585 +--rw lsp-pacing-interval? uint16 586 +--rw lsp-retransmit-interval? uint16 587 +--rw passive? boolean 588 +--rw csnp-interval? uint16 589 +--rw hello-padding 590 | +--rw enable? boolean 591 +--rw mesh-group-enable? mesh-group-state 592 +--rw mesh-group? uint8 593 +--rw interface-type? interface-type 594 +--rw enable? boolean {admin-control}? 595 +--rw tag* uint32 {prefix-tag}? 596 +--rw tag64* uint64 {prefix-tag64}? 597 +--rw node-flag? boolean {node-flag}? 598 +--rw hello-authentication 599 | +--rw (authentication-type)? 600 | | +--:(key-chain) {key-chain}? 601 | | | +--rw key-chain? key-chain:key-chain-ref 602 | | +--:(password) 603 | | +--rw key? string 604 | | +--rw (algorithm)? 605 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 606 | | | +--rw hmac-sha1-12? empty 607 | | +--:(md5) 608 | | | +--rw md5? empty 609 | | +--:(sha-1) 610 | | | +--rw sha-1? empty 611 | | +--:(hmac-sha-1) 612 | | | +--rw hmac-sha-1? empty 613 | | +--:(hmac-sha-256) 614 | | | +--rw hmac-sha-256? empty 615 | | +--:(hmac-sha-384) 616 | | | +--rw hmac-sha-384? empty 617 | | +--:(hmac-sha-512) 618 | | +--rw hmac-sha-512? empty 619 | +--rw level-1 620 | | +--rw (authentication-type)? 621 | | +--:(key-chain) {key-chain}? 622 | | | +--rw key-chain? key-chain:key-chain-ref 623 | | +--:(password) 624 | | +--rw key? string 625 | | +--rw (algorithm)? 626 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 627 | | | +--rw hmac-sha1-12? empty 628 | | +--:(md5) 629 | | | +--rw md5? empty 630 | | +--:(sha-1) 631 | | | +--rw sha-1? empty 632 | | +--:(hmac-sha-1) 633 | | | +--rw hmac-sha-1? empty 634 | | +--:(hmac-sha-256) 635 | | | +--rw hmac-sha-256? empty 636 | | +--:(hmac-sha-384) 637 | | | +--rw hmac-sha-384? empty 638 | | +--:(hmac-sha-512) 639 | | +--rw hmac-sha-512? empty 640 | +--rw level-2 641 | +--rw (authentication-type)? 642 | +--:(key-chain) {key-chain}? 643 | | +--rw key-chain? key-chain:key-chain-ref 644 | +--:(password) 645 | +--rw key? string 646 | +--rw (algorithm)? 647 | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 648 | | +--rw hmac-sha1-12? empty 649 | +--:(md5) 650 | | +--rw md5? empty 651 | +--:(sha-1) 652 | | +--rw sha-1? empty 653 | +--:(hmac-sha-1) 654 | | +--rw hmac-sha-1? empty 655 | +--:(hmac-sha-256) 656 | | +--rw hmac-sha-256? empty 657 | +--:(hmac-sha-384) 658 | | +--rw hmac-sha-384? empty 659 | +--:(hmac-sha-512) 660 | +--rw hmac-sha-512? empty 661 +--rw hello-interval 662 | +--rw value? uint16 663 | +--rw level-1 664 | | +--rw value? uint16 665 | +--rw level-2 666 | +--rw value? uint16 667 +--rw hello-multiplier 668 | +--rw value? uint16 669 | +--rw level-1 670 | | +--rw value? uint16 671 | +--rw level-2 672 | +--rw value? uint16 673 +--rw priority 674 | +--rw value? uint8 675 | +--rw level-1 676 | | +--rw value? uint8 677 | +--rw level-2 678 | +--rw value? uint8 679 +--rw metric 680 | +--rw value? wide-metric 681 | +--rw level-1 682 | | +--rw value? wide-metric 683 | +--rw level-2 684 | +--rw value? wide-metric 685 +--rw bfd {bfd}? 686 | +--rw enable? boolean 687 +--rw afs {nlpid-control}? 688 | +--rw af* [af] 689 | +--rw af identityref 690 +--rw mpls 691 | +--rw igp-ldp-sync {igp-ldp-sync}? 692 | +--rw enable? boolean 693 +--rw fast-reroute {fast-reroute}? 694 | +--rw lfa {lfa}? 695 | +--rw candidate-disabled? boolean 696 | +--rw enable? boolean 697 | +--rw remote-lfa {remote-lfa}? 698 | | +--rw enable? boolean 699 | +--rw level-1 700 | | +--rw candidate-disabled? boolean 701 | | +--rw enable? boolean 702 | | +--rw remote-lfa {remote-lfa}? 703 | | +--rw enable? boolean 704 | +--rw level-2 705 | +--rw candidate-disabled? boolean 706 | +--rw enable? boolean 707 | +--rw remote-lfa {remote-lfa}? 708 | +--rw enable? boolean 709 +--rw topologies {multi-topology}? 710 +--rw topology* [name] 711 +--rw name leafref 712 +--rw fast-reroute {fast-reroute}? 713 | +--rw lfa {lfa}? 714 | +--rw candidate-disabled? boolean 715 | +--rw enable? boolean 716 | +--rw remote-lfa {remote-lfa}? 717 | | +--rw enable? boolean 718 | +--rw level-1 719 | | +--rw candidate-disabled? boolean 720 | | +--rw enable? boolean 721 | | +--rw remote-lfa {remote-lfa}? 722 | | +--rw enable? boolean 723 | +--rw level-2 724 | +--rw candidate-disabled? boolean 725 | +--rw enable? boolean 726 | +--rw remote-lfa {remote-lfa}? 727 | +--rw enable? boolean 728 +--rw metric 729 +--rw value? wide-metric 730 +--rw level-1 731 | +--rw value? wide-metric 732 +--rw level-2 733 +--rw value? wide-metric 735 2.5. Authentication Parameters 737 The module enables authentication configuration through the IETF key- 738 chain module ([I-D.ietf-rtgwg-yang-key-chain]). The IS-IS module 739 imports the "ietf-key-chain" module and reuses some groupings to 740 allow global and per interface configuration of authentication. If a 741 global authentication is configured, an implementation SHOULD 742 authenticate PSNP, CSNP and LSPs with the authentication parameters 743 supplied. The authentication of hello PDUs can be activated on a per 744 interface basis. 746 2.6. IGP/LDP synchronization 748 [RFC5443] defines a mechanism where IGP needs to be synchronized with 749 LDP. An "igp-ldp-sync" feature has been defined in the model to 750 support this mechanism. The "mpls/igp-ldp-sync" container under 751 "interface" allows activation of the mechanism on a per interface 752 basis. The "mpls/igp-ldp-sync" container in the global configuration 753 is empty on purpose and is not required for the activation. The goal 754 of this empty container is to allow easy augmentation with additional 755 parameters like timers for example. 757 2.7. ISO parameters 759 As IS-IS protocol is based on ISO protocol suite, some ISO parameters 760 may be required. 762 This module augments interface configuration model to support ISO 763 configuration parameters. 765 The clns-mtu can be defined under the interface. 767 2.8. IP FRR 769 This YANG model supports LFA ([RFC5286]) and remote LFA ([RFC7490]) 770 as IP FRR techniques. The "fast-reroute" container may be augmented 771 by other models to support other IPFRR flavors (MRT, TILFA ...). 773 The current version of the model supports activation of LFA and 774 remote LFA at interface only. The global "lfa" container is present 775 but kept empty to allow augmentation with vendor specific properties 776 like policies. 778 Remote LFA is considered as a child of LFA. Remote LFA cannot be 779 enabled if LFA is not enabled. 781 The "candidate-disabled" allows to mark an interface to not be used 782 as a backup. 784 2.9. Operational State 786 A "isis" container provides operational states for IS-IS. This 787 container is divided in multiple components: 789 o system-counters : provides statistical informations about the 790 global system. 792 o interface : provides configuration state information for each 793 interface. 795 o adjacencies: provides state information about current IS-IS 796 adjacencies. 798 o spf-log: provides information about SPF events on the node. 800 o lsp-log: provides information about LSP events on the node 801 (reception of an LSP or modification of local LSP). 803 o database: provides details on current LSDB. 805 o hostnames: provides information about system-id to hostname 806 mappings. 808 o fast-reroute: provides information about IP FRR. 810 3. RPC Operations 812 The "ietf-isis" module defines two RPC operations: 814 o clear-isis-database: reset the content of a particular IS-IS 815 database and restart database synchronization with the neighbors. 817 o clear-isis-adjacency: restart a particular set of IS-IS 818 adjacencies. 820 rpcs: 821 +---x clear-adjacency 822 | +--ro input 823 | +--ro routing-protocol-instance-name instance-state-ref 824 | +--ro level? level 825 | +--ro interface? string 826 +---x clear-database 827 +--ro input 828 +--ro routing-protocol-instance-name instance-state-ref 829 +--ro level? level 831 4. Notifications 833 The "ietf-isis" module introduces some notifications : 835 database-overload : raised when overload condition is changed. 837 lsp-too-large : raised when the system tries to propagate a too 838 large PDU. 840 corrupted-lsp-detected : raised when the system find that an LSP 841 that was stored in memory has become corrupted. 843 attempt-to-exceed-max-sequence : This notification is sent when 844 the system wraps the 32-bit sequence counter of an LSP. 846 id-len-mismatch : This notification is sent when we receive a PDU 847 with a different value for the System ID length. 849 max-area-addresses-mismatch : This notification is sent when we 850 receive a PDU with a different value for the Maximum Area 851 Addresses. 853 own-lsp-purge : This notification is sent when the system receives 854 a PDU with its own system ID and zero age. 856 sequence-number-skipped : This notification is sent when the 857 system receives a PDU with its own system ID and different 858 contents. The system has to reissue the LSP with a higher 859 sequence number. 861 authentication-type-failure : This notification is sent when the 862 system receives a PDU with the wrong authentication type field. 864 authentication-failure : This notification is sent when the system 865 receives a PDU with the wrong authentication information. 867 version-skew : This notification is sent when the system receives 868 a PDU with a different protocol version number. 870 area-mismatch : This notification is sent when the system receives 871 a Hello PDU from an IS that does not share any area address. 873 rejected-adjacency : This notification is sent when the system 874 receives a Hello PDU from an IS but does not establish an 875 adjacency for some reason. 877 protocols-supported-mismatch : This notification is sent when the 878 system receives a non pseudonode LSP that has no matching protocol 879 supported. 881 lsp-error-detected : This notification is sent when the system 882 receives a LSP with a parse error. 884 adjacency-change : This notification is sent when an IS-IS 885 adjacency moves to Up state or to Down state. 887 lsp-received : This notification is sent when a LSP is received. 889 lsp-generation : This notification is sent when a LSP is 890 regenerated. 892 notifications: 893 +---n database-overload 894 | +--ro instance-name?

Segment Routing 1028 The IS-IS SR YANG module is augmenting IS-IS module for both 1029 configuration and operational states. 1031 The IS-IS SR YANG module requires the base segment routing module 1032 ([I-D.ietf-spring-sr-yang]) to be supported as there is a strong 1033 relationship between those modules. 1035 The figure below describe the overall structure of the isis-sr YANG 1036 module: 1038 module: ietf-isis-sr 1039 augment /rt:routing/rt:control-plane-protocols/rt:control-plane-protocol 1040 /isis:isis: 1041 +--rw segment-routing 1042 | +--rw enabled?

Segment Routing activation 1169 Activation of segment-routing IS-IS is done by setting the "enable" 1170 leaf to true. This triggers advertisement of segment-routing 1171 extensions based on the configuration parameters that have been setup 1172 using the base segment routing module. 1174 5.2. Advertising mapping server policy 1176 The base segment routing module defines mapping server policies. By 1177 default, IS-IS will not advertise nor receive any mapping server 1178 entry. The IS-IS segment-routing module allows to advertise one or 1179 multiple mapping server policies through the "bindings/advertise/ 1180 policies" leaf-list. The "bindings/receive" leaf allows to enable 1181 the reception of mapping server entries. 1183 5.3. IP Fast reroute 1185 IS-IS SR model augments the fast-reroute container under interface. 1186 It brings the ability to activate TI-LFA (topology independent LFA) 1187 and also enhances remote LFA to use segment-routing tunneling instead 1188 of LDP. 1190 6. Interaction with Other YANG Modules 1192 The "isis" configuration container augments the "/rt:routing/ 1193 rt:control-plane-protocols/control-plane-protocol" container of the 1194 ietf-routing [I-D.ietf-netmod-routing-cfg] module by defining IS-IS 1195 specific parameters. 1197 The "isis" module augments "/if:interfaces/if:interface" with ISO 1198 specific parameters. 1200 The "isis" operational state container augments the "/rt:routing- 1201 state/rt:control-plane-protocols/control-plane-protocol" container of 1202 the ietf-routing module by defining IS-IS specific operational 1203 states. 1205 Some IS-IS specific routes attributes are added to route objects of 1206 the ietf-routing module by augmenting "/rt:routing- 1207 state/rt:ribs/rt:rib/rt:routes/rt:route". 1209 The modules defined in this document use some groupings from ietf- 1210 keychain [I-D.ietf-rtgwg-yang-key-chain] and ietf-segment routing 1211 [I-D.ietf-spring-sr-yang]. 1213 7.

Security Considerations 5434 Configuration and state data defined in this document are designed to 5435 be accessed via the NETCONF protocol [RFC6241]. 5437 As IS-IS is an IGP protocol (critical piece of the network), ensuring 5438 stability and security of the protocol is mandatory for the network 5439 service. 5441 Authors recommends to implement NETCONF access control model 5442 ([RFC6536]) to restrict access to all or part of the configuration to 5443 specific users. Access control to RPCs is also critical as RPC 5444 allows to clear protocol datastructures that would definitively 5445 impact the network service. This kind of RPC needs only to be used 5446 in specific cases by well-known experienced users. 5448 Authors consider that all the configuration is considered as 5449 sensitive/vulnerable as well as RPCs. But security teams can decide 5450 to open some part of the configuration to less experienced users 5451 depending on the internal organization, for example: 5453 o User FullWrite: would access to the whole data model. This kind 5454 of profile may be restricted to few experienced people. 5456 o User PartialWrite: would only access to configuration part within 5457 /isis/interfaces/interface. So this kind of profile is restricted 5458 to creation/modification/deletion of interfaces. This profile 5459 does not have access to RPC. 5461 o User Read: would only access to state part /isis-state. 5463 Unauthorized access to configuration or RPC may cause high damages to 5464 the network service. 5466 The /isis-state/database may contain authentication information. As 5467 presented in the description of the /isis-state/database/level- 5468 1/lsp/authentication/authentication-key, the authentication MUST 5469 never be presented in plaintext format for security reason. Authors 5470 recommend the usage of MD5 to display or return the authentication- 5471 key. 5473 Some authentication-key may also be present in the /isis 5474 configuration. When configuring IS-IS using the NETCONF protocol, 5475 authors recommends the usage of secure transport of NETCONF using SSH 5476 ([RFC6242]). 5478 10. Contributors 5480 Authors would like to thank Kiran Agrahara Sreenivasa, Dean 5481 Bogdanovic, Yingzhen Qu, Yi Yang for their major contributions to the 5482 draft. 5484 11. Acknowledgements 5486 TBD. 5488 12. IANA Considerations 5490 The IANA is requested to assign two new URIs from the IETF XML 5491 registry ([RFC3688]).
