IPv6 routes
Use any of the these commands in ROUTER ISIS ADDRESS-FAMILY IPV6 mode to add routes from
other routing instances or protocols.
Use the
show running-config isis command in EXEC Privilege mode to view IS-IS configuration globally
(including both IPv4 and IPv6 settings), or the
show config command in ROUTER ISIS mode to view the
current IPv4 IS-IS configuration, or the
show config command in ROUTER ISIS-ADDRESS FAMILY
IPV6 mode to view the current IPv6 IS-IS configuration
Configure authentication passwords
You can assign an authentication password for routers in Level 1 and for routers in Level 2. Since Level 1
and Level 2 routers do not communicate with each other, you can assign different passwords for Level 1
routers and for Level 2 routers. If you want the routers in the level to communicate with each other, though,
they must be configured with the same password.
Note: These commands apply to IPv6 IS-IS only. Use the ROUTER ISIS mode previously shown to apply
prefix lists to IPv4 routes.
