Usage guidelines
IPv6 IS-IS considers redistributed routes as AS-external routes.
You can specify a cost and a level for redistributed routes.
The import-route bgp4+ command redistributes only EBGP routes. The import-route bgp4+ allow-ibgp
command redistributes both EBGP and IBGP routes, and might cause routing loops. Therefore, use it with
caution.
Examples
# Configure IPv6–IS-IS to redistribute static routes and set the cost for redistributed routes to 15.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] ipv6 import-route static cost 15
ipv6 import-route isisv6 level-1 into level-2
Use ipv6 import-route isisv6 level-1 into level-2 to enable route advertisement from Level-1 to Level-2.
Use undo ipv6 import-route isisv6 level-1 into level-2 to restore the default.
Syntax
ipv6 import-route isisv6 level-1 into level-2 [ filter-policy { acl6-number | prefix-list prefix-list-name |
route-policy route-policy-name } | tag tag ] *
undo ipv6 import-route isisv6 level-1 into level-2
