Configuring IPv6 IS-IS route control
Before you configure IPv6 IS-IS route control, complete basic IPv6 IS-IS configuration.
To configure IPv6 IS-IS route control:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IS-IS view.
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
N/A
3. Specify a preference for
IPv6 IS-IS routes. ipv6 preference { route-policy
route-policy-name | preference } * By default, the default
setting is 15.
4. Configure an IPv6 IS-IS
summary route.
ipv6 summary ipv6-prefix prefix-length
[ avoid-feedback | generate_null0_route |
[ level-1 | level-1-2 | level-2 ] | tag tag ] *
By default, no IPv6 IS-IS
summary route is
configured.
5. Generate an IPv6 IS-IS
default route.
ipv6 default-route-advertise [ [ level-1 |
level-1-2 | level-2 ] | route-policy
route-policy-name ] *
By default, no IPv6 default
route is generated.
6. Configure IPv6 IS-IS to
filter redistributed routes.
ipv6 filter-policy { acl6-number | prefix-list
prefix-list-name | route-policy
route-policy-name } export [ protocol
[ process-id ] ]
By default, IPv6 IS-IS does
not filter redistributed
routes.
This command is usually
used together with the ipv6
import-route command.
7. Configure IPv6 IS-IS to
filter received routes.
ipv6 filter-policy { acl6-number | prefix-list
prefix-list-name | route-policy
route-policy-name } import
By default, IPv6 IS-IS does
not filter received routes.
8. Configure IPv6 IS-IS to
redistribute routes from
another routing protocol.
ipv6 import-route protocol [ process-id ]
[ allow-ibgp ] [ cost cost | [ level-1 | level-1-2
| level-2 ] | route-policy route-policy-name |
tag tag ] *
By default, IPv6 IS-IS does
not redistribute routes from
any other routing protocol.
9. Configure the maximum
number of redistributed
Level 1/Level 2 IPv6
routes.
ipv6 import-route limit number
By default, the maximum
number of redistributed
Level 1/Level 2 IPv6 routes
is not configured.
10. Configure route
advertisement from Level-2
to Level-1.
ipv6 import-route isisv6 level-2 into level-1
[ filter-policy { acl6-number | prefix-list
prefix-list-name | route-policy
route-policy-name } | tag tag ] *
By default, IPv6 IS-IS does
not advertise routes from
Level-2 to Level-1.
11. Configure route
advertisement from Level-1
to Level-2.
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 ] *
By default, IPv6 IS-IS
advertises routes from
Level-1 to Level-2.
