Introduction 91 This document defines a YANG data model for ISIS routing protocol. 93 The data model covers configuration of an ISIS routing protocol 94 instance as well as operational states. 96 1.1. Tree diagram 98 A simplified graphical representation of the data model is presented 99 in Section 2. 101 The meaning of the symbols in these diagrams is as follows: 103 o Brackets "[" and "]" enclose list keys. 105 o Curly braces "{" and "}" contain names of optional features that 106 make the corresponding node conditional. 108 o Abbreviations before data node names: "rw" means configuration 109 (read-write), and "ro" state data (read-only). 111 o Symbols after data node names: "?" means an optional node and "*" 112 denotes a "list" or "leaf-list". 114 o Parentheses enclose choice and case nodes, and case nodes are also 115 marked with a colon (":"). 117 o Ellipsis ("...") stands for contents of subtrees that are not 118 shown. 120 2. Design of the Data Model 122 The ISIS YANG module is divided in two main "isis" containers that 123 are augmenting the "routing-protocol" lists in ietf-routing module 124 with specific ISIS parameters. 126 One container contains the writable parameters, while the other 127 contains the operational states. 129 The figure below describe the overall structure of the isis YANG 130 module: 132 module: ietf-isis 133 augment /rt:routing-state/rt:routing-instance/rt:ribs/rt:rib 134 /rt:routes/rt:route: 135 +--ro metric?

ISIS Configuration 434 The ISIS configuration supports a VRF-centric configuration approach. 435 The isis configuration is applied directly within the appropriate 436 routing-instance where ISIS is activated. 438 The ISIS configuration container is divided in: 440 o Global parameters. 442 o Per interface configuration (see Section 2.4). 444 It would to up to extension modules to augment this model to support 445 vendor specific parameters. 447 2.2. Multitopology Parameters 449 The "topologies" list is used to enable support of MT extensions for 450 specific address families. 452 Each topology should refer to an existing RIB. 454 Some specific parameters could be defined for a specific topology at 455 global level and also at interface level. 457 2.3. Per-Level Parameters 459 Some parameters support per level configuration. In this case, the 460 parameter is built as a list, so different values could be used for 461 each level. The "level-all" permits to apply a value to both levels. 463 +--rw priority* [level] 464 | +--rw value? uint8 465 | +--rw level level 467 Example : 469 470 100 471 level-1 472 473 474 200 475 level-2 476 478 As a list is used, a user may decide to apply a level-1, level-2 and 479 level-all parameter at the same time. An implementation SHOULD 480 prefer a level specific parameter over level-all parameter. As 481 example, if priority is 100 for level-1, 200 for level-2 and 250 for 482 level-all, the implementation should use 100 for level-1 and 200 for 483 level-2. 485 2.4. Per-Interface Parameters 487 The per-interface section of the ISIS instance describes the 488 interface specific parameters. 490 The interface is a reference to an interface in the Interface YANG 491 model. 493 Each interface has interface-specific parameters that may have a 494 different value per level as described in previous section. An 495 interface-specific parameter always override an ISIS global parameter 496 . 498 Some parameters like BFD and hello-padding are defined as containers 499 to permit easy extension by vendor specific modules. 501 +--rw interfaces 502 +--rw interface* [name] 503 +--rw name if:interface-ref 504 +--rw level-type? level 505 +--rw lsp-pacing-interval? uint16 506 +--rw lsp-retransmit-interval? uint16 507 +--rw passive? boolean 508 +--rw csnp-interval? uint16 509 +--rw hello-padding 510 | +--rw enable? boolean 511 +--rw mesh-group-enable? mesh-group-state 512 +--rw mesh-group? uint8 513 +--rw interface-type? interface-type 514 +--rw enable? boolean {admin-control}? 515 +--rw tag* uint32 {prefix-tag}? 516 +--rw tag64* uint64 {prefix-tag64}? 517 +--rw hello-authentication* [level] 518 | +--rw (authentication-type)? 519 | | +--:(key-chain) {key-chain}? 520 | | | +--rw key-chain? key-chain:key-chain-ref 521 | | +--:(password) 522 | | +--rw key? string 523 | | +--rw (algorithm)? 524 | | +--:(hmac-sha-1-12) {crypto-hmac-sha-1-12}? 525 | | | ... 526 | | +--:(md5) 527 | | | ... 528 | | +--:(sha-1) 529 | | | ... 530 | | +--:(hmac-sha-1) 531 | | | ... 532 | | +--:(hmac-sha-256) 533 | | | ... 534 | | +--:(hmac-sha-384) 535 | | | ... 536 | | +--:(hmac-sha-512) 537 | | ... 538 | +--rw level level 539 +--rw hello-interval* [level] 540 | +--rw value? uint16 541 | +--rw level level 542 +--rw hello-multiplier* [level] 543 | +--rw value? uint16 544 | +--rw level level 545 +--rw priority* [level] 546 | +--rw value? uint8 547 | +--rw level level 548 +--rw metric* [level] 549 | +--rw value? wide-metric 550 | +--rw level level 551 +--rw af* [af] 552 | +--rw af identityref 553 | +--rw bfd-cfg 554 | +--rw enabled? boolean 555 | +--rw local-multiplier? multiplier 556 | +--rw (interval-config-type)? 557 | +--:(tx-rx-intervals) 558 | | +--rw desired-min-tx-interval uint32 559 | | +--rw required-min-rx-interval uint32 560 | +--:(single-interval) 561 | +--rw min-interval uint32 562 +--rw mpls 563 | +--rw igp-ldp-sync {igp-ldp-sync}? 564 | +--rw enable? boolean 565 +--rw fast-reroute {fast-reroute}? 566 | +--rw lfa* [level] {lfa}? 567 | +--rw candidate-disabled? boolean 568 | +--rw enable? boolean 569 | +--rw remote-lfa {remote-lfa}? 570 | | +--rw enable? boolean 571 | +--rw level level 572 +--rw topologies* [name] 573 +--rw name leafref 574 +--rw fast-reroute {fast-reroute}? 575 | +--rw lfa* [level] {lfa}? 576 | +--rw candidate-disabled? boolean 577 | +--rw enable? boolean 578 | +--rw remote-lfa {remote-lfa}? 579 | | +--rw enable? boolean 580 | +--rw level level 581 +--rw metric* [level] 582 +--rw value? wide-metric 583 +--rw level level 585 2.5.

IP FRR 596 This YANG model supports LFA and remote LFA as IP FRR techniques. 597 The "fast-reroute" container may be augmented by other models to 598 support other IPFRR flavors (MRT ...). 600 The current version of the model supports activation of LFA and 601 remote LFA at interface only. The global "lfa" container is present 602 but kept empty to permit augmentation with vendor specific properties 603 like policies. 605 Remote LFA is considered as a child of LFA. Remote LFA cannot be 606 enabled if LFA is not enabled. 608 The "candidate-disabled" permit to mark an interface to not be used 609 as a backup. 611 2.7. Operational State 613 "isis" container provides operational states for ISIS. This 614 container is divided in multiple components: 616 o system-counters : provides statistical informations about the 617 global system. 619 o interface : provides configuration state information for each 620 interface. 622 o adjacencies: provides state information about current ISIS 623 adjacencies. 625 o spf-log: provides information about SPF events on the node. 627 o lsp-log: provides information about LSP events on the node 628 (reception of an LSP or modification of local LSP). 630 o database: provides details on current LSDB. 632 o hostnames: provides information about system-id to hostname 633 mappings. 635 o fast-reroute: provides information about IP FRR. 637 3. RPC Operations 639 The "ietf-isis" module defines two RPC operations: 641 o clear-isis-database: reset the content of a particular ISIS 642 database and restart database synchronization with the neighbors. 644 o clear-isis-adjacency: restart a particular set of ISIS 645 adjacencies. 647 rpcs: 648 +---x clear-adjacency 649 | +--ro input 650 | +--ro routing-instance-name rt:routing-instance-state-ref 651 | +--ro routing-protocol-instance-name instance-state-ref 652 | +--ro level? level 653 | +--ro interface? string 654 +---x clear-database 655 +--ro input 656 +--ro routing-instance-name rt:routing-instance-state-ref 657 +--ro routing-protocol-instance-name instance-state-ref 658 +--ro level? level 660 4. Notifications 662 The "ietf-isis" module introduces some notifications : 664 database-overload : raised when overload condition is changed. 666 lsp-too-large : raised when the system tries to propagate a too 667 large PDU. 669 corrupted-lsp-detected : raised when the system find that an LSP 670 that was stored in memory has become corrupted. 672 attempt-to-exceed-max-sequence : This notification is sent when 673 the system wraps the 32-bit sequence counter of an LSP. 675 id-len-mismatch : This notification is sent when we receive a PDU 676 with a different value for the System ID length. 678 max-area-addresses-mismatch : This notification is sent when we 679 receive a PDU with a different value for the Maximum Area 680 Addresses. 682 own-lsp-purge : This notification is sent when the system receives 683 a PDU with its own system ID and zero age. 685 sequence-number-skipped : This notification is sent when the 686 system receives a PDU with its own system ID and different 687 contents. The system has to reissue the LSP with a higher 688 sequence number. 690 authentication-type-failure : This notification is sent when the 691 system receives a PDU with the wrong authentication type field. 693 authentication-failure : This notification is sent when the system 694 receives a PDU with the wrong authentication information. 696 version-skew : This notification is sent when the system receives 697 a PDU with a different protocol version number. 699 area-mismatch : This notification is sent when the system receives 700 a Hello PDU from an IS that does not share any area address. 702 rejected-adjacency : This notification is sent when the system 703 receives a Hello PDU from an IS but does not establish an 704 adjacency for some reason. 706 protocols-supported-mismatch : This notification is sent when the 707 system receives a non pseudonode LSP that has no matching protocol 708 supported. 710 lsp-error-detected : This notification is sent when the system 711 receives a LSP with a parse error. 713 adjacency-change : This notification is sent when an ISIS 714 adjacency moves to Up state or to Down state. 716 lsp-received : This notification is sent when a LSP is received. 718 lsp-generation : This notification is sent when a LSP is 719 regenerated. 721 notifications: 722 +---n database-overload 723 | +--ro instance-name?

Segment Routing 857 The IS-IS SR YANG module is augmenting IS-IS module for both 858 configuration and operational states. 860 The IS-IS SR YANG module requires the base segment routing module 861 ([I-D.litkowski-spring-sr-yang]) to be supported as there is a strong 862 relationship between those modules. 864 The figure below describe the overall structure of the isis-sr YANG 865 module: 867 module: ietf-isis-sr 868 augment /rt:routing/rt:routing-instance/rt:routing-protocols 869 /rt:routing-protocol/isis:isis: 870 +--rw segment-routing 871 +--rw enabled?

Segment Routing activation 1000 Activation of segment-routing IS-IS is done by setting the "enabled" 1001 leaf to true. This triggers advertisement of segment-routing 1002 extensions based on the configuration parameters that have been setup 1003 using the base segment routing module. 1005 5.2. Advertising mapping server policy 1007 The base segment routing module defines mapping server policies. By 1008 default, IS-IS will not advertise nor receive any mapping server 1009 entry. The IS-IS segment-routing module permits to advertise one or 1010 multiple mapping server policies through the "bindings/advertise/ 1011 policies" leaf-list. The "bindings/receive" leaf permits to enable 1012 the reception of mapping server entries. 1014 5.3. IP Fast reroute 1016 IS-IS SR model augments the fast-reroute container under interface. 1017 It brings the ability to activate TI-LFA (topology independent LFA) 1018 and also enhances remote LFA to use segment-routing tunneling instead 1019 of LDP. 1021 6. Interaction with Other YANG Modules 1023 The "isis" configuration container augments the "/rt:routing/ 1024 rt:routing-instance/rt:routing-protocols/routing-protocol" container 1025 of the ietf-routing module by defining IS-IS specific parameters. 1027 The "isis" module augments "/if:interfaces/if:interface" with ISO 1028 specific parameters. 1030 The "isis" operational state container augments the "/rt:routing- 1031 state/rt:routing-instance/rt:routing-protocols/routing-protocol" 1032 container of the ietf-routing module by defining ISIS specific 1033 operational states. 1035 Some ISIS specific routes attributes are added to route objects of 1036 the ietf-routing module by augmenting "/rt:routing- 1037 state/rt:ribs/rt:rib/rt:routes/rt:route" and "/rt:fib- 1038 route/rt:output/rt:route". 1040 The module uses some groupings from ietf-keychain, routing-policy and 1041 ietf-bfd modules. 1043 7.

Security Considerations 5255 Configuration and state data defined in this document are designed to 5256 be accessed via the NETCONF protocol [RFC6241]. 5258 As ISIS is an IGP protocol (critical piece of the network), ensuring 5259 stability and security of the protocol is mandatory for the network 5260 service. 5262 Authors recommends to implement NETCONF access control model 5263 ([RFC6536]) to restrict access to all or part of the configuration to 5264 specific users. Access control to RPCs is also critical as RPC 5265 permits to clear protocol datastructures that would definitively 5266 impact the network service. This kind of RPC needs only to be used 5267 in specific cases by well-known experienced users. 5269 Authors consider that all the configuration is considered as 5270 sensitive/vulnerable as well as RPCs. But security teams can decide 5271 to open some part of the configuration to less experienced users 5272 depending on the internal organization, for example: 5274 o User FullWrite: would access to the whole data model. This kind 5275 of profile may be restricted to few experienced people. 5277 o User PartialWrite: would only access to configuration part within 5278 /isis/interfaces/interface. So this kind of profile is restricted 5279 to creation/modification/deletion of interfaces. This profile 5280 does not have access to RPC. 5282 o User Read: would only access to state part /isis-state. 5284 Unauthorized access to configuration or RPC may cause high damages to 5285 the network service. 5287 The /isis-state/database may contain authentication information. As 5288 presented in the description of the /isis-state/database/level- 5289 1/lsp/authentication/authentication-key, the authentication MUST 5290 never be presented in plaintext format for security reason. Authors 5291 recommends the usage of MD5 to present the authentication-key. 5293 Some authentication-key may also be present in the /isis 5294 configuration. When configuring ISIS using the NETCONF protocol, 5295 authors recommends the usage of secure transport of NETCONF using SSH 5296 ([RFC6242]). 5298 10.
