Introduction 100 This document defines a YANG data model for IS-IS routing protocol. 102 The data model covers configuration of an IS-IS routing protocol 103 instance as well as operational states. 105 1.1. Tree diagram 107 A simplified graphical representation of the data model is presented 108 in Section 2. 110 The meaning of the symbols in these diagrams is as follows: 112 o Brackets "[" and "]" enclose list keys. 114 o Curly braces "{" and "}" contain names of optional features that 115 make the corresponding node conditional. 117 o Abbreviations before data node names: "rw" means configuration 118 (read-write), and "ro" state data (read-only). 120 o Symbols after data node names: "?" means an optional node and "*" 121 denotes a "list" or "leaf-list". 123 o Parentheses enclose choice and case nodes, and case nodes are also 124 marked with a colon (":"). 126 o Ellipsis ("...") stands for contents of subtrees that are not 127 shown. 129 2. Design of the Data Model 131 The IS-IS YANG module is divided in two main "isis" containers that 132 are augmenting the "control-plane-protocol" lists in ietf-routing 133 module with specific IS-IS parameters. 135 One container contains the writable parameters, while the other 136 contains the operational states. 138 The figure below describes the overall structure of the isis YANG 139 module: 141 module: ietf-isis 142 augment /rt:routing-state/rt:ribs/rt:rib/rt:routes/rt:route: 143 +--ro metric?

IS-IS Configuration 493 The IS-IS configuration container is divided in: 495 o Global parameters. 497 o Per interface configuration (see Section 2.4). 499 Additional modules may be created this to support any additional 500 parameters. These additional modules should augment the ietf-isis 501 module. 503 The model implements features, thus some of the configuration 504 statement becomes optional. As an example, the ability to control 505 the administrative state of a particular IS-IS instance is optional. 506 By advertising the feature "admin-control", a device communicates to 507 the client that it supports the ability to shutdown a particular IS- 508 IS instance. 510 The global configuration contains usual IS-IS parameters such as lsp- 511 mtu, lsp-lifetime, lsp-refresh, default-metric... 513 2.2. Multitopology Parameters 515 The model supports multitopology (MT) IS-IS as defined in [RFC5120]. 517 The "topologies" container is used to enable support of MT 518 extensions. 520 The "name" used in the topology list should refer to an existing RIB 521 of the device. 523 Some specific parameters could be defined on a per topology basis 524 both at global level and at interface level: for example, an 525 interface metric can be defined per topology. 527 Multiple address families (like IPv4 or IPv6) can also be activated 528 within the default topology. This can be achieved using the "afs" 529 container (requiring "nlpid-control" feature to be advertised). 531 2.3. Per-Level Parameters 533 Some parameters allow a per level configuration. In this case, the 534 parameter is modeled as a container with three configuration 535 locations: 537 o a top level container: corresponds to level-1-2, so the 538 configuration applies to both levels. 540 o a level-1 container: corresponds to level-1 specific parameters. 542 o a level-2 container: corresponds to level-2 specific parameters. 544 +--rw priority 545 | +--rw value? uint8 546 | +--rw level-1 547 | | +--rw value? uint8 548 | +--rw level-2 549 | +--rw value? uint8 551 Example: 553 554 250 555 556 100 557 558 559 200 560 561 563 An implementation SHOULD prefer a level specific parameter over a 564 level-all parameter. As example, if the priority is 100 for the 565 level-1, 200 for the level-2 and 250 for the top level configuration, 566 the implementation should use 100 for the level-1 and 200 for the 567 level-2. 569 Some parameters like "overload bit" and "route preference" are not 570 modeled to support a per level configuration. If an implementation 571 supports per level configuration for such parameter, this 572 implementation SHOULD augment the current model by adding both 573 level-1 and level-2 containers and SHOULD reuse existing 574 configuration groupings. 576 Example of augmentation: 578 augment "/rt:routing/" + 579 "rt:control-plane-protocols/rt:control-plane-protocol"+ 580 "/isis:isis/isis:overload" { 581 when "rt:type = 'isis:isis'" { 582 description 583 "This augment IS-IS routing protocol when used"; 584 } 585 description 586 "This augments IS-IS overload configuration 587 with per level configuration."; 589 container level-1 { 590 uses isis:overload-global-cfg; 591 description 592 "Level 1 configuration."; 593 } 594 container level-2 { 595 uses isis:overload-global-cfg; 596 description 597 "Level 2 configuration."; 598 } 600 } 602 If an implementation does not support per level configuration for a 603 parameter modeled with per level configuration, the implementation 604 SHOULD advertise a deviation to announce the non support of the 605 level-1 and level-2 containers. 607 Finally, if an implementation supports per level configuration but 608 does not support the level-1-2 configuration, it SHOULD also 609 advertise a deviation. 611 2.4. Per-Interface Parameters 613 The per-interface section of the IS-IS instance describes the 614 interface specific parameters. 616 The interface is modeled as a reference to an existing interface 617 defined in the "ietf-interfaces" YANG model. 619 Each interface has some interface-specific parameters that may have a 620 different per level value as described in previous section. An 621 interface-specific parameter always override an IS-IS global 622 parameter. 624 Some parameters like hello-padding are defined as containers to allow 625 easy extension by vendor specific modules. 627 +--rw interfaces 628 +--rw interface* [name] 629 +--rw name if:interface-ref 630 +--rw level-type? level 631 +--rw lsp-pacing-interval? uint16 632 +--rw lsp-retransmit-interval? uint16 633 +--rw passive? boolean 634 +--rw csnp-interval? uint16 635 +--rw hello-padding 636 | +--rw enable? boolean 637 +--rw mesh-group-enable? mesh-group-state 638 +--rw mesh-group? uint8 639 +--rw interface-type? interface-type 640 +--rw enable? boolean {admin-control}? 641 +--rw tag* uint32 {prefix-tag}? 642 +--rw tag64* uint64 {prefix-tag64}? 643 +--rw node-flag? boolean {node-flag}? 644 +--rw hello-authentication 645 | +--rw (authentication-type)? 646 | | +--:(key-chain) {key-chain}? 647 | | | +--rw key-chain? key-chain:key-chain-ref 648 | | +--:(password) 649 | | +--rw key? string 650 | | +--rw (algorithm)? 651 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 652 | | | +--rw hmac-sha1-12? empty 653 | | +--:(md5) 654 | | | +--rw md5? empty 655 | | +--:(sha-1) 656 | | | +--rw sha-1? empty 657 | | +--:(hmac-sha-1) 658 | | | +--rw hmac-sha-1? empty 659 | | +--:(hmac-sha-256) 660 | | | +--rw hmac-sha-256? empty 661 | | +--:(hmac-sha-384) 662 | | | +--rw hmac-sha-384? empty 663 | | +--:(hmac-sha-512) 664 | | +--rw hmac-sha-512? empty 665 | +--rw level-1 666 | | +--rw (authentication-type)? 667 | | +--:(key-chain) {key-chain}? 668 | | | +--rw key-chain? key-chain:key-chain-ref 669 | | +--:(password) 670 | | +--rw key? string 671 | | +--rw (algorithm)? 672 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 673 | | | +--rw hmac-sha1-12? empty 674 | | +--:(md5) 675 | | | +--rw md5? empty 676 | | +--:(sha-1) 677 | | | +--rw sha-1? empty 678 | | +--:(hmac-sha-1) 679 | | | +--rw hmac-sha-1? empty 680 | | +--:(hmac-sha-256) 681 | | | +--rw hmac-sha-256? empty 682 | | +--:(hmac-sha-384) 683 | | | +--rw hmac-sha-384? empty 684 | | +--:(hmac-sha-512) 685 | | +--rw hmac-sha-512? empty 686 | +--rw level-2 687 | +--rw (authentication-type)? 688 | +--:(key-chain) {key-chain}? 689 | | +--rw key-chain? key-chain:key-chain-ref 690 | +--:(password) 691 | +--rw key? string 692 | +--rw (algorithm)? 693 | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 694 | | +--rw hmac-sha1-12? empty 695 | +--:(md5) 696 | | +--rw md5? empty 697 | +--:(sha-1) 698 | | +--rw sha-1? empty 699 | +--:(hmac-sha-1) 700 | | +--rw hmac-sha-1? empty 701 | +--:(hmac-sha-256) 702 | | +--rw hmac-sha-256? empty 703 | +--:(hmac-sha-384) 704 | | +--rw hmac-sha-384? empty 705 | +--:(hmac-sha-512) 706 | +--rw hmac-sha-512? empty 707 +--rw hello-interval 708 | +--rw value? uint16 709 | +--rw level-1 710 | | +--rw value? uint16 711 | +--rw level-2 712 | +--rw value? uint16 713 +--rw hello-multiplier 714 | +--rw value? uint16 715 | +--rw level-1 716 | | +--rw value? uint16 717 | +--rw level-2 718 | +--rw value? uint16 719 +--rw priority 720 | +--rw value? uint8 721 | +--rw level-1 722 | | +--rw value? uint8 723 | +--rw level-2 724 | +--rw value? uint8 725 +--rw metric 726 | +--rw value? wide-metric 727 | +--rw level-1 728 | | +--rw value? wide-metric 729 | +--rw level-2 730 | +--rw value? wide-metric 731 +--rw bfd {bfd}? 732 | +--rw enable? boolean 733 +--rw afs {nlpid-control}? 734 | +--rw af* [af] 735 | +--rw af identityref 736 +--rw mpls 737 | +--rw ldp 738 | +--rw igp-sync? boolean {ldp-igp-sync}? 739 +--rw fast-reroute {fast-reroute}? 740 | +--rw lfa {lfa}? 741 | +--rw candidate-disabled? boolean 742 | +--rw enable? boolean 743 | +--rw remote-lfa {remote-lfa}? 744 | | +--rw enable? boolean 745 | +--rw level-1 746 | | +--rw candidate-disabled? boolean 747 | | +--rw enable? boolean 748 | | +--rw remote-lfa {remote-lfa}? 749 | | +--rw enable? boolean 750 | +--rw level-2 751 | +--rw candidate-disabled? boolean 752 | +--rw enable? boolean 753 | +--rw remote-lfa {remote-lfa}? 754 | +--rw enable? boolean 755 +--rw topologies {multi-topology}? 756 +--rw topology* [name] 757 +--rw name leafref 758 +--rw metric 759 +--rw value? wide-metric 760 +--rw level-1 761 | +--rw value? wide-metric 762 +--rw level-2 763 +--rw value? wide-metric 765 2.5. Authentication Parameters 767 The module enables authentication configuration through the IETF key- 768 chain module ([I-D.ietf-rtgwg-yang-key-chain]). The IS-IS module 769 imports the "ietf-key-chain" module and reuses some groupings to 770 allow global and per interface configuration of authentication. If a 771 global authentication is configured, an implementation SHOULD 772 authenticate PSNPs, CSNPs and LSPs with the authentication parameters 773 supplied. The authentication of hello PDUs can be activated on a per 774 interface basis. 776 2.6. IGP/LDP synchronization 778 [RFC5443] defines a mechanism where IGP needs to be synchronized with 779 LDP. An "ldp-igp-sync" feature has been defined in the model to 780 support this mechanism. The "mpls/ldp/igp-sync" leaf under 781 "interface" allows activation of the mechanism on a per interface 782 basis. The "mpls/ldp/igp-sync" container in the global configuration 783 is empty on purpose and is not required for the activation. The goal 784 of this empty container is to allow easy augmentation with additional 785 parameters like timers for example. 787 2.7. ISO parameters 789 As IS-IS protocol is based on ISO protocol suite, some ISO parameters 790 may be required. 792 This module augments interface configuration model to support ISO 793 configuration parameters. 795 The clns-mtu can be defined under the interface. 797 2.8. IP FRR 799 This YANG model supports LFA ([RFC5286]) and remote LFA ([RFC7490]) 800 as IP FRR techniques. The "fast-reroute" container may be augmented 801 by other models to support other IPFRR flavors (MRT, TILFA ...). 803 The current version of the model supports activation of LFA and 804 remote LFA at interface only. The global "lfa" container is present 805 but kept empty to allow augmentation with vendor specific properties 806 like policies. 808 Remote LFA is considered as a child of LFA. Remote LFA cannot be 809 enabled if LFA is not enabled. 811 The "candidate-disabled" allows to mark an interface to not be used 812 as a backup. 814 2.9. Operational States 816 An "isis" container provides operational states for IS-IS. This 817 container is divided in multiple components: 819 o system-counters : provides statistical informations about the 820 global system. 822 o interface : provides configuration state informations for each 823 interface. 825 o adjacencies: provides state informations about current IS-IS 826 adjacencies. 828 o spf-log: provides informations about SPF events on the node. 830 o lsp-log: provides informations about LSP events on the node 831 (reception of an LSP or modification of local LSP). 833 o local-rib: provides the IS-IS internal routing table view. 835 o database: provides details on the current LSDB. 837 o hostnames: provides informations about system-id to hostname 838 mappings. 840 o fast-reroute: provides informations about IP FRR. 842 3. RPC Operations 844 The "ietf-isis" module defines two RPC operations: 846 o clear-isis-database: reset the content of a particular IS-IS 847 database and restart database synchronization with the neighbors. 849 o clear-isis-adjacency: restart a particular set of IS-IS 850 adjacencies. 852 rpcs: 853 +---x clear-adjacency 854 | +--ro input 855 | +--ro routing-protocol-instance-name instance-state-ref 856 | +--ro level? level 857 | +--ro interface? string 858 +---x clear-database 859 +--ro input 860 +--ro routing-protocol-instance-name instance-state-ref 861 +--ro level? level 863 4. Notifications 865 The "ietf-isis" module introduces some notifications : 867 database-overload : raised when overload condition is changed. 869 lsp-too-large : raised when the system tries to propagate a too 870 large PDU. 872 corrupted-lsp-detected : raised when the system find that an LSP 873 that was stored in memory has become corrupted. 875 attempt-to-exceed-max-sequence : This notification is sent when 876 the system wraps the 32-bit sequence counter of an LSP. 878 id-len-mismatch : This notification is sent when we receive a PDU 879 with a different value for the System ID length. 881 max-area-addresses-mismatch : This notification is sent when we 882 receive a PDU with a different value for the Maximum Area 883 Addresses. 885 own-lsp-purge : This notification is sent when the system receives 886 a PDU with its own system ID and zero age. 888 sequence-number-skipped : This notification is sent when the 889 system receives a PDU with its own system ID and different 890 contents. The system has to reissue the LSP with a higher 891 sequence number. 893 authentication-type-failure : This notification is sent when the 894 system receives a PDU with the wrong authentication type field. 896 authentication-failure : This notification is sent when the system 897 receives a PDU with the wrong authentication information. 899 version-skew : This notification is sent when the system receives 900 a PDU with a different protocol version number. 902 area-mismatch : This notification is sent when the system receives 903 a Hello PDU from an IS that does not share any area address. 905 rejected-adjacency : This notification is sent when the system 906 receives a Hello PDU from an IS but does not establish an 907 adjacency for some reason. 909 protocols-supported-mismatch : This notification is sent when the 910 system receives a non pseudonode LSP that has no matching protocol 911 supported. 913 lsp-error-detected : This notification is sent when the system 914 receives a LSP with a parse error. 916 adjacency-change : This notification is sent when an IS-IS 917 adjacency moves to Up state or to Down state. 919 lsp-received : This notification is sent when a LSP is received. 921 lsp-generation : This notification is sent when a LSP is 922 regenerated. 924 notifications: 925 +---n database-overload 926 | +--ro routing-instance?

Interaction with Other YANG Modules 1085 The "isis" configuration container augments the "/rt:routing/ 1086 rt:control-plane-protocols/control-plane-protocol" container of the 1087 ietf-routing [I-D.ietf-netmod-routing-cfg] module by defining IS-IS 1088 specific parameters. 1090 The "isis" module augments "/if:interfaces/if:interface" with ISO 1091 specific parameters. 1093 The "isis" operational state container augments the "/rt:routing- 1094 state/rt:control-plane-protocols/control-plane-protocol" container of 1095 the ietf-routing module by defining IS-IS specific operational 1096 states. 1098 Some IS-IS specific routes attributes are added to route objects of 1099 the ietf-routing module by augmenting "/rt:routing- 1100 state/rt:ribs/rt:rib/rt:routes/rt:route". 1102 The modules defined in this document use some groupings from ietf- 1103 keychain [I-D.ietf-rtgwg-yang-key-chain]. 1105 6.

Security Considerations 4837 Configuration and state data defined in this document are designed to 4838 be accessed via the NETCONF protocol [RFC6241]. 4840 As IS-IS is an IGP protocol (critical piece of the network), ensuring 4841 stability and security of the protocol is mandatory for the network 4842 service. 4844 Authors recommends to implement NETCONF access control model 4845 ([RFC6536]) to restrict access to all or part of the configuration to 4846 specific users. Access control to RPCs is also critical as RPC 4847 allows to clear protocol datastructures that would definitively 4848 impact the network service. This kind of RPC needs only to be used 4849 in specific cases by well-known experienced users. 4851 Authors consider that all the configuration is considered as 4852 sensitive/vulnerable as well as RPCs. But security teams can decide 4853 to open some part of the configuration to less experienced users 4854 depending on the internal organization, for example: 4856 o User FullWrite: would access to the whole data model. This kind 4857 of profile may be restricted to few experienced people. 4859 o User PartialWrite: would only access to configuration part within 4860 /isis/interfaces/interface. So this kind of profile is restricted 4861 to creation/modification/deletion of interfaces. This profile 4862 does not have access to RPC. 4864 o User Read: would only access to the operational states. 4866 Unauthorized access to configuration or RPC may cause high damages to 4867 the network service. 4869 The "isis/database" may contain authentication information. As 4870 presented in the description of the "/isis/database/level- 4871 1/lsp/authentication/authentication-key", the authentication MUST 4872 never be displayed in a plaintext format for security reason. 4873 Authors recommend the usage of MD5 to display or return the 4874 authentication-key. 4876 Some authentication-key may also be required in the "isis" writable 4877 container. When configuring IS-IS using the NETCONF protocol, 4878 authors recommends the usage of secure transport of NETCONF using SSH 4879 ([RFC6242]). 4881 8.

Acknowledgements 4889 TBD. 4891 10. IANA Considerations 4893 The IANA is requested to assign two new URIs from the IETF XML 4894 registry ([RFC3688]). Authors are suggesting the following URI: 4896 URI: urn:ietf:params:xml:ns:yang:ietf-isis 4897 Registrant Contact: IS-IS WG 4898 XML: N/A, the requested URI is an XML namespace 4900 This document also requests one new YANG module name in the YANG 4901 Module Names registry ([RFC6020]) with the following suggestion: 4903 name: ietf-isis 4904 namespace: urn:ietf:params:xml:ns:yang:ietf-isis 4905 prefix: isis 4906 reference: RFC XXXX 4908 11.
