Configuring Keychains for IS-IS

This task explains how to configure keychains for IS-IS. This task is optional.
Keychains can be configured at the router level ( lsp-password command) and at the interface level (
hello-password command) within IS-IS. These commands reference the global keychain configuration and
instruct the IS-IS protocol to obtain security parameters from the global set of configured keychains. The
router-level configuration (lsp-password command) sets the keychain to be used for all IS-IS LSPs generated
by this router, as well as for all Sequence Number Protocol Data Units (SN PDUs). The keychain used for
HELLO PDUs is set at the interface level, and may be set differently for each interface configured for IS-IS.
SUMMARY STEPS
1. configure
2. router isis instance-id
3. l sp-password keychain keychain-name [ level { 1 | 2 }] [ send-only ] [ snp send-only ]
4. interface type interface-path-id
5. h ello-password keychain keychain-name [ level { 1 | 2 }] [ send-only ]
6. commit
