Introduction 94 This document defines a YANG data model for IS-IS routing protocol. 96 The data model covers configuration of an IS-IS routing protocol 97 instance as well as operational states. 99 1.1. Tree diagram 101 A simplified graphical representation of the data model is presented 102 in Section 2. 104 The meaning of the symbols in these diagrams is as follows: 106 o Brackets "[" and "]" enclose list keys. 108 o Curly braces "{" and "}" contain names of optional features that 109 make the corresponding node conditional. 111 o Abbreviations before data node names: "rw" means configuration 112 (read-write), and "ro" state data (read-only). 114 o Symbols after data node names: "?" means an optional node and "*" 115 denotes a "list" or "leaf-list". 117 o Parentheses enclose choice and case nodes, and case nodes are also 118 marked with a colon (":"). 120 o Ellipsis ("...") stands for contents of subtrees that are not 121 shown. 123 2. Design of the Data Model 125 The IS-IS YANG module is divided in two main "isis" containers that 126 are augmenting the "routing-protocol" lists in ietf-routing module 127 with specific IS-IS parameters. 129 One container contains the writable parameters, while the other 130 contains the operational states. 132 The figure below describe the overall structure of the isis YANG 133 module: 135 module: ietf-isis 136 augment /rt:routing-state/rt:routing-instance/rt:ribs/rt:rib 137 /rt:routes/rt:route: 138 +--ro metric?

IS-IS Configuration 426 The IS-IS configuration supports a VRF-centric configuration 427 approach. The isis configuration is applied directly within the 428 appropriate routing-instance where IS-IS is activated. 430 The IS-IS configuration container is divided in: 432 o Global parameters. 434 o Per interface configuration (see Section 2.4). 436 It would to up to extension modules to augment this model to support 437 vendor specific parameters. 439 2.2. Multitopology Parameters 441 The "topologies" list is used to enable support of MT extensions for 442 specific address families. 444 Each topology should refer to an existing RIB. 446 Some specific parameters could be defined for a specific topology at 447 global level and also at interface level. 449 2.3. Per-Level Parameters 451 Some parameters support per level configuration. In this case, the 452 parameter is built as a list, so different values could be used for 453 each level. The "level-all" permits to apply a value to both levels. 455 +--rw priority* [level] 456 | +--rw value? uint8 457 | +--rw level level 459 Example : 461 462 100 463 level-1 464 465 466 200 467 level-2 468 470 As a list is used, a user may decide to apply a level-1, level-2 and 471 level-all parameter at the same time. An implementation SHOULD 472 prefer a level specific parameter over level-all parameter. As 473 example, if priority is 100 for level-1, 200 for level-2 and 250 for 474 level-all, the implementation should use 100 for level-1 and 200 for 475 level-2. 477 Overload bit and route preference are exceptions to this general 478 modelling approach. In order to accommodate differences between 479 existing implementations, overload, overload-max-metric and 480 preference are modelled as container without per-level configuration. 481 This let the opportunity for vendor to augment those containers with 482 per-level configuration. An implementation that augments those 483 containers with per-level configuration SHOULD : 485 o Create one container for level-1 and one container for level-2. 487 o Reuse the grouping defined for configuration parameters and apply 488 them in level-1 and level-2 containers. 490 In this case, the value defined in the top-level container SHOULD be 491 applied to both levels while the value defined in a specific level 492 container SHOULD apply to this level only and SHOULD override the 493 top-level value if defined. 495 Example of augmentation : 497 augment "/rt:routing-state/rt:routing-instance/" + 498 "rt:routing-protocols/rt:routing-protocol"+ 499 "/isis:isis/isis:overload" { 500 when "rt:type = 'isis:isis'" { 501 description 502 "This augment IS-IS routing protocol when used"; 503 } 504 description 505 "This augments IS-IS overload configuration 506 with per level configuration."; 508 container level-1 { 509 uses isis:overload-config; 510 description 511 "Level 1 configuration."; 512 } 513 container level-2 { 514 uses isis:overload-config; 515 description 516 "Level 2 configuration."; 517 } 519 } 521 2.4. Per-Interface Parameters 523 The per-interface section of the IS-IS instance describes the 524 interface specific parameters. 526 The interface is a reference to an interface in the Interface YANG 527 model. 529 Each interface has interface-specific parameters that may have a 530 different value per level as described in previous section. An 531 interface-specific parameter always override an IS-IS global 532 parameter . 534 Some parameters like BFD and hello-padding are defined as containers 535 to permit easy extension by vendor specific modules. 537 TODO : interfaces.tree 539 2.5. ISO parameters 541 Some ISO parameters may be required. 543 This module augments interface configuration model to support ISO 544 configuration parameters. 546 The clns-mtu can be defined under the interface. 548 2.6. IP FRR 550 This YANG model supports LFA and remote LFA as IP FRR techniques. 551 The "fast-reroute" container may be augmented by other models to 552 support other IPFRR flavors (MRT ...). 554 The current version of the model supports activation of LFA and 555 remote LFA at interface only. The global "lfa" container is present 556 but kept empty to permit augmentation with vendor specific properties 557 like policies. 559 Remote LFA is considered as a child of LFA. Remote LFA cannot be 560 enabled if LFA is not enabled. 562 The "candidate-disabled" permit to mark an interface to not be used 563 as a backup. 565 2.7. Operational State 567 "isis" container provides operational states for IS-IS. This 568 container is divided in multiple components: 570 o system-counters : provides statistical informations about the 571 global system. 573 o interface : provides configuration state information for each 574 interface. 576 o adjacencies: provides state information about current IS-IS 577 adjacencies. 579 o spf-log: provides information about SPF events on the node. 581 o lsp-log: provides information about LSP events on the node 582 (reception of an LSP or modification of local LSP). 584 o database: provides details on current LSDB. 586 o hostnames: provides information about system-id to hostname 587 mappings. 589 o fast-reroute: provides information about IP FRR. 591 3. RPC Operations 593 The "ietf-isis" module defines two RPC operations: 595 o clear-isis-database: reset the content of a particular IS-IS 596 database and restart database synchronization with the neighbors. 598 o clear-isis-adjacency: restart a particular set of IS-IS 599 adjacencies. 601 rpcs: 602 +---x clear-adjacency 603 | +--ro input 604 | +--ro routing-instance-name rt:routing-instance-state-ref 605 | +--ro routing-protocol-instance-name instance-state-ref 606 | +--ro level? level 607 | +--ro interface? string 608 +---x clear-database 609 +--ro input 610 +--ro routing-instance-name rt:routing-instance-state-ref 611 +--ro routing-protocol-instance-name instance-state-ref 612 +--ro level? level 614 4. Notifications 616 The "ietf-isis" module introduces some notifications : 618 database-overload : raised when overload condition is changed. 620 lsp-too-large : raised when the system tries to propagate a too 621 large PDU. 623 corrupted-lsp-detected : raised when the system find that an LSP 624 that was stored in memory has become corrupted. 626 attempt-to-exceed-max-sequence : This notification is sent when 627 the system wraps the 32-bit sequence counter of an LSP. 629 id-len-mismatch : This notification is sent when we receive a PDU 630 with a different value for the System ID length. 632 max-area-addresses-mismatch : This notification is sent when we 633 receive a PDU with a different value for the Maximum Area 634 Addresses. 636 own-lsp-purge : This notification is sent when the system receives 637 a PDU with its own system ID and zero age. 639 sequence-number-skipped : This notification is sent when the 640 system receives a PDU with its own system ID and different 641 contents. The system has to reissue the LSP with a higher 642 sequence number. 644 authentication-type-failure : This notification is sent when the 645 system receives a PDU with the wrong authentication type field. 647 authentication-failure : This notification is sent when the system 648 receives a PDU with the wrong authentication information. 650 version-skew : This notification is sent when the system receives 651 a PDU with a different protocol version number. 653 area-mismatch : This notification is sent when the system receives 654 a Hello PDU from an IS that does not share any area address. 656 rejected-adjacency : This notification is sent when the system 657 receives a Hello PDU from an IS but does not establish an 658 adjacency for some reason. 660 protocols-supported-mismatch : This notification is sent when the 661 system receives a non pseudonode LSP that has no matching protocol 662 supported. 664 lsp-error-detected : This notification is sent when the system 665 receives a LSP with a parse error. 667 adjacency-change : This notification is sent when an IS-IS 668 adjacency moves to Up state or to Down state. 670 lsp-received : This notification is sent when a LSP is received. 672 lsp-generation : This notification is sent when a LSP is 673 regenerated. 675 notifications: 676 +---n database-overload 677 | +--ro instance-name?

Segment Routing 811 The IS-IS SR YANG module is augmenting IS-IS module for both 812 configuration and operational states. 814 The IS-IS SR YANG module requires the base segment routing module 815 ([I-D.ietf-spring-sr-yang]) to be supported as there is a strong 816 relationship between those modules. 818 The figure below describe the overall structure of the isis-sr YANG 819 module: 821 module: ietf-isis-sr 822 augment /rt:routing/rt:routing-instance/rt:routing-protocols/rt:routing-protocol 823 /isis:isis: 824 +--rw segment-routing 825 | +--rw enabled?

Segment Routing activation 953 Activation of segment-routing IS-IS is done by setting the "enabled" 954 leaf to true. This triggers advertisement of segment-routing 955 extensions based on the configuration parameters that have been setup 956 using the base segment routing module. 958 5.2. Advertising mapping server policy 960 The base segment routing module defines mapping server policies. By 961 default, IS-IS will not advertise nor receive any mapping server 962 entry. The IS-IS segment-routing module permits to advertise one or 963 multiple mapping server policies through the "bindings/advertise/ 964 policies" leaf-list. The "bindings/receive" leaf permits to enable 965 the reception of mapping server entries. 967 5.3. IP Fast reroute 969 IS-IS SR model augments the fast-reroute container under interface. 970 It brings the ability to activate TI-LFA (topology independent LFA) 971 and also enhances remote LFA to use segment-routing tunneling instead 972 of LDP. 974 6. BFD 976 Additionally this document defines a module that can be used to 977 configure and monitor the IS-IS BFD feature. 979 Bidirectional Forwarding Detection (BFD) ([RFC5880]) is a network 980 protocol that is used for liveness detection of arbitrary paths 981 between systems. A YANG data model is defined in 982 ([I-D.ietf-bfd-yang]) that supports BFD configuration and management. 984 As a client of BFD, the IS-IS protocol uses the services provided by 985 BFD. The IS-IS BFD YANG augments the base IS-IS module and is 986 defined as a separate module. So any implementation that does not 987 support BFD can still use the IS-IS base model without having to 988 import the BFD module ([I-D.ietf-bfd-yang]). 990 module: ietf-isis-bfd 991 augment /rt:routing/rt:routing-instance/rt:routing-protocols 992 /rt:routing-protocol/isis:isis/isis:interfaces/isis:interface: 993 +--rw bfd 994 +--rw enabled? boolean 995 +--rw local-multiplier? multiplier 996 +--rw (interval-config-type)? 997 +--:(tx-rx-intervals) 998 | +--rw desired-min-tx-interval uint32 999 | +--rw required-min-rx-interval uint32 1000 +--:(single-interval) 1001 +--rw min-interval uint32 1002 augment /rt:routing-state/rt:routing-instance/rt:routing-protocols 1003 /rt:routing-protocol/isis:isis/isis:interfaces/isis:interface: 1004 +--ro bfd 1005 +--ro enabled? boolean 1006 +--ro local-multiplier? multiplier 1007 +--ro (interval-config-type)? 1008 +--:(tx-rx-intervals) 1009 | +--ro desired-min-tx-interval uint32 1010 | +--ro required-min-rx-interval uint32 1011 +--:(single-interval) 1012 +--ro min-interval uint32 1014 7. Interaction with Other YANG Modules 1016 The "isis" configuration container augments the "/rt:routing/ 1017 rt:routing-instance/rt:routing-protocols/routing-protocol" container 1018 of the ietf-routing module by defining IS-IS specific parameters. 1020 The "isis" module augments "/if:interfaces/if:interface" with ISO 1021 specific parameters. 1023 The "isis" operational state container augments the "/rt:routing- 1024 state/rt:routing-instance/rt:routing-protocols/routing-protocol" 1025 container of the ietf-routing module by defining IS-IS specific 1026 operational states. 1028 Some IS-IS specific routes attributes are added to route objects of 1029 the ietf-routing module by augmenting "/rt:routing- 1030 state/rt:ribs/rt:rib/rt:routes/rt:route" and "/rt:fib- 1031 route/rt:output/rt:route". 1033 The modules defined in this document use some groupings from ietf- 1034 keychain, routing-policy and ietf-bfd modules. 1036 8.

Security Considerations 5371 Configuration and state data defined in this document are designed to 5372 be accessed via the NETCONF protocol [RFC6241]. 5374 As IS-IS is an IGP protocol (critical piece of the network), ensuring 5375 stability and security of the protocol is mandatory for the network 5376 service. 5378 Authors recommends to implement NETCONF access control model 5379 ([RFC6536]) to restrict access to all or part of the configuration to 5380 specific users. Access control to RPCs is also critical as RPC 5381 permits to clear protocol datastructures that would definitively 5382 impact the network service. This kind of RPC needs only to be used 5383 in specific cases by well-known experienced users. 5385 Authors consider that all the configuration is considered as 5386 sensitive/vulnerable as well as RPCs. But security teams can decide 5387 to open some part of the configuration to less experienced users 5388 depending on the internal organization, for example: 5390 o User FullWrite: would access to the whole data model. This kind 5391 of profile may be restricted to few experienced people. 5393 o User PartialWrite: would only access to configuration part within 5394 /isis/interfaces/interface. So this kind of profile is restricted 5395 to creation/modification/deletion of interfaces. This profile 5396 does not have access to RPC. 5398 o User Read: would only access to state part /isis-state. 5400 Unauthorized access to configuration or RPC may cause high damages to 5401 the network service. 5403 The /isis-state/database may contain authentication information. As 5404 presented in the description of the /isis-state/database/level- 5405 1/lsp/authentication/authentication-key, the authentication MUST 5406 never be presented in plaintext format for security reason. Authors 5407 recommends the usage of MD5 to present the authentication-key. 5409 Some authentication-key may also be present in the /isis 5410 configuration. When configuring IS-IS using the NETCONF protocol, 5411 authors recommends the usage of secure transport of NETCONF using SSH 5412 ([RFC6242]). 5414 12.
