Introduction 91 This document defines a YANG data model for IS-IS routing protocol. 93 The data model covers configuration of an IS-IS 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 IS-IS YANG module is divided in two main "isis" containers that 123 are augmenting the "routing-protocol" lists in ietf-routing module 124 with specific IS-IS 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:ribs/rt:rib/rt:routes/rt:route: 134 +--ro metric?

IS-IS Configuration 433 The IS-IS configuration container is divided in: 435 o Global parameters. 437 o Per interface configuration (see Section 2.4). 439 It would to up to extension modules to augment this model to support 440 vendor specific parameters. 442 2.2. Multitopology Parameters 444 The "topologies" list is used to enable support of MT extensions for 445 specific address families. 447 Each topology should refer to an existing RIB. 449 Some specific parameters could be defined for a specific topology at 450 global level and also at interface level. 452 2.3. Per-Level Parameters 454 Some parameters support per level configuration. In this case, the 455 parameter is built as a container with three levels of configuration 456 : 458 o top level : corresponds to level-1-2, so the configuration applies 459 to both levels. 461 o level-1 : corresponds to level-1 specific parameter. 463 o level-2 : corresponds to level-2 specific parameter. 465 +--rw priority 466 | +--rw value? uint8 467 | +--rw level-1 468 | | +--rw value? uint8 469 | +--rw level-2 470 | +--rw value? uint8 472 Example : 474 475 250 476 477 100 478 479 480 200 481 482 484 An implementation SHOULD prefer a level specific parameter over 485 level-all parameter. As example, if priority is 100 for level-1, 200 486 for level-2 and 250 for top level configuration, the implementation 487 should use 100 for level-1 and 200 for level-2. 489 Some parameters like overload bit and route preference are not 490 modelled for per level configuration. If an implementation supports 491 per level configuration for such parameter, the implementation SHOULD 492 augment the current model by adding level-1 and level-2 containers 493 and reusing existing configuration groupings. 495 Example of augmentation : 497 augment "/rt:routing/" + 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-global-cfg; 510 description 511 "Level 1 configuration."; 512 } 513 container level-2 { 514 uses isis:overload-global-cfg; 515 description 516 "Level 2 configuration."; 517 } 519 } 520 Moreover, if an implementation does not support per level 521 configuration for a parameter, like priority, which has per level 522 configuration, the implementation SHOULD advertise a deviation to 523 announce the non support of the level-1 and level-2 containers. 525 Finally, if an implementation supports per level configuration but 526 does not support the level-1-2 configuration, it SHOULD also 527 advertise a deviation. 529 2.4. Per-Interface Parameters 531 The per-interface section of the IS-IS instance describes the 532 interface specific parameters. 534 The interface is a reference to an interface in the Interface YANG 535 model. 537 Each interface has interface-specific parameters that may have a 538 different value per level as described in previous section. An 539 interface-specific parameter always override an IS-IS global 540 parameter . 542 Some parameters like hello-padding are defined as containers to 543 permit easy extension by vendor specific modules. 545 TODO : interfaces.tree 547 2.5. ISO parameters 549 Some ISO parameters may be required. 551 This module augments interface configuration model to support ISO 552 configuration parameters. 554 The clns-mtu can be defined under the interface. 556 2.6. IP FRR 558 This YANG model supports LFA and remote LFA as IP FRR techniques. 559 The "fast-reroute" container may be augmented by other models to 560 support other IPFRR flavors (MRT ...). 562 The current version of the model supports activation of LFA and 563 remote LFA at interface only. The global "lfa" container is present 564 but kept empty to permit augmentation with vendor specific properties 565 like policies. 567 Remote LFA is considered as a child of LFA. Remote LFA cannot be 568 enabled if LFA is not enabled. 570 The "candidate-disabled" permit to mark an interface to not be used 571 as a backup. 573 2.7. Operational State 575 "isis" container provides operational states for IS-IS. This 576 container is divided in multiple components: 578 o system-counters : provides statistical informations about the 579 global system. 581 o interface : provides configuration state information for each 582 interface. 584 o adjacencies: provides state information about current IS-IS 585 adjacencies. 587 o spf-log: provides information about SPF events on the node. 589 o lsp-log: provides information about LSP events on the node 590 (reception of an LSP or modification of local LSP). 592 o database: provides details on current LSDB. 594 o hostnames: provides information about system-id to hostname 595 mappings. 597 o fast-reroute: provides information about IP FRR. 599 3. RPC Operations 601 The "ietf-isis" module defines two RPC operations: 603 o clear-isis-database: reset the content of a particular IS-IS 604 database and restart database synchronization with the neighbors. 606 o clear-isis-adjacency: restart a particular set of IS-IS 607 adjacencies. 609 rpcs: 610 +---x clear-adjacency 611 | +--ro input 612 | +--ro routing-protocol-instance-name instance-state-ref 613 | +--ro level? level 614 | +--ro interface? string 615 +---x clear-database 616 +--ro input 617 +--ro routing-protocol-instance-name instance-state-ref 618 +--ro level? level 620 4. Notifications 622 The "ietf-isis" module introduces some notifications : 624 database-overload : raised when overload condition is changed. 626 lsp-too-large : raised when the system tries to propagate a too 627 large PDU. 629 corrupted-lsp-detected : raised when the system find that an LSP 630 that was stored in memory has become corrupted. 632 attempt-to-exceed-max-sequence : This notification is sent when 633 the system wraps the 32-bit sequence counter of an LSP. 635 id-len-mismatch : This notification is sent when we receive a PDU 636 with a different value for the System ID length. 638 max-area-addresses-mismatch : This notification is sent when we 639 receive a PDU with a different value for the Maximum Area 640 Addresses. 642 own-lsp-purge : This notification is sent when the system receives 643 a PDU with its own system ID and zero age. 645 sequence-number-skipped : This notification is sent when the 646 system receives a PDU with its own system ID and different 647 contents. The system has to reissue the LSP with a higher 648 sequence number. 650 authentication-type-failure : This notification is sent when the 651 system receives a PDU with the wrong authentication type field. 653 authentication-failure : This notification is sent when the system 654 receives a PDU with the wrong authentication information. 656 version-skew : This notification is sent when the system receives 657 a PDU with a different protocol version number. 659 area-mismatch : This notification is sent when the system receives 660 a Hello PDU from an IS that does not share any area address. 662 rejected-adjacency : This notification is sent when the system 663 receives a Hello PDU from an IS but does not establish an 664 adjacency for some reason. 666 protocols-supported-mismatch : This notification is sent when the 667 system receives a non pseudonode LSP that has no matching protocol 668 supported. 670 lsp-error-detected : This notification is sent when the system 671 receives a LSP with a parse error. 673 adjacency-change : This notification is sent when an IS-IS 674 adjacency moves to Up state or to Down state. 676 lsp-received : This notification is sent when a LSP is received. 678 lsp-generation : This notification is sent when a LSP is 679 regenerated. 681 notifications: 682 +---n database-overload 683 | +--ro instance-name?

Segment Routing 817 The IS-IS SR YANG module is augmenting IS-IS module for both 818 configuration and operational states. 820 The IS-IS SR YANG module requires the base segment routing module 821 ([I-D.ietf-spring-sr-yang]) to be supported as there is a strong 822 relationship between those modules. 824 The figure below describe the overall structure of the isis-sr YANG 825 module: 827 module: ietf-isis-sr 828 augment /rt:routing/rt:routing-protocols/rt:routing-protocol/isis:isis: 829 +--rw segment-routing 830 | +--rw enabled?

Segment Routing activation 957 Activation of segment-routing IS-IS is done by setting the "enabled" 958 leaf to true. This triggers advertisement of segment-routing 959 extensions based on the configuration parameters that have been setup 960 using the base segment routing module. 962 5.2. Advertising mapping server policy 964 The base segment routing module defines mapping server policies. By 965 default, IS-IS will not advertise nor receive any mapping server 966 entry. The IS-IS segment-routing module permits to advertise one or 967 multiple mapping server policies through the "bindings/advertise/ 968 policies" leaf-list. The "bindings/receive" leaf permits to enable 969 the reception of mapping server entries. 971 5.3. IP Fast reroute 973 IS-IS SR model augments the fast-reroute container under interface. 974 It brings the ability to activate TI-LFA (topology independent LFA) 975 and also enhances remote LFA to use segment-routing tunneling instead 976 of LDP. 978 6. Interaction with Other YANG Modules 980 The "isis" configuration container augments the "/rt:routing/ 981 rt:routing-protocols/routing-protocol" container of the ietf-routing 982 [I-D.ietf-netmod-routing-cfg] module by defining IS-IS specific 983 parameters. 985 The "isis" module augments "/if:interfaces/if:interface" with ISO 986 specific parameters. 988 The "isis" operational state container augments the "/rt:routing- 989 state/rt:routing-protocols/routing-protocol" container of the ietf- 990 routing module by defining IS-IS specific operational states. 992 Some IS-IS specific routes attributes are added to route objects of 993 the ietf-routing module by augmenting "/rt:routing- 994 state/rt:ribs/rt:rib/rt:routes/rt:route" and "/rt:fib- 995 route/rt:output/rt:route". 997 The modules defined in this document use some groupings from ietf- 998 keychain [I-D.ietf-rtgwg-yang-key-chain] and ietf-segment routing 999 [I-D.ietf-spring-sr-yang]. 1001 7.

Security Considerations 5380 Configuration and state data defined in this document are designed to 5381 be accessed via the NETCONF protocol [RFC6241]. 5383 As IS-IS is an IGP protocol (critical piece of the network), ensuring 5384 stability and security of the protocol is mandatory for the network 5385 service. 5387 Authors recommends to implement NETCONF access control model 5388 ([RFC6536]) to restrict access to all or part of the configuration to 5389 specific users. Access control to RPCs is also critical as RPC 5390 permits to clear protocol datastructures that would definitively 5391 impact the network service. This kind of RPC needs only to be used 5392 in specific cases by well-known experienced users. 5394 Authors consider that all the configuration is considered as 5395 sensitive/vulnerable as well as RPCs. But security teams can decide 5396 to open some part of the configuration to less experienced users 5397 depending on the internal organization, for example: 5399 o User FullWrite: would access to the whole data model. This kind 5400 of profile may be restricted to few experienced people. 5402 o User PartialWrite: would only access to configuration part within 5403 /isis/interfaces/interface. So this kind of profile is restricted 5404 to creation/modification/deletion of interfaces. This profile 5405 does not have access to RPC. 5407 o User Read: would only access to state part /isis-state. 5409 Unauthorized access to configuration or RPC may cause high damages to 5410 the network service. 5412 The /isis-state/database may contain authentication information. As 5413 presented in the description of the /isis-state/database/level- 5414 1/lsp/authentication/authentication-key, the authentication MUST 5415 never be presented in plaintext format for security reason. Authors 5416 recommends the usage of MD5 to present the authentication-key. 5418 Some authentication-key may also be present in the /isis 5419 configuration. When configuring IS-IS using the NETCONF protocol, 5420 authors recommends the usage of secure transport of NETCONF using SSH 5421 ([RFC6242]). 5423 10.
