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:
1. Enter system view.
system-view
N/A
2. Enter IS-IS view.
isis
[ process-id ] [
vpn-instance
vpn-instance-name ]
N/A
3. Enter IS-IS IPv6 address
family view.
address-family ipv6
[
unicast
]
N/A
4. Specify a preference for
IPv6 IS-IS routes.
preference
{
route-policy
route-policy-name | preference } *
By default, the default
setting is 15.
5. Configure an IPv6 IS-IS
summary route.
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.
6. Configure IPv6 IS-IS to
advertise a default route.
default-route-advertise
[
avoid-learning
|
[
level-1
|
level-1-2
|
level-2
] |
route-policy
route-policy-name |
tag
tag ] *
By default, IPv6 IS-IS does
not advertise Level-1 and
Level-2 default routes.
7. Configure IPv6 IS-IS to
filter redistributed routes.
filter-policy
{ ipv6-acl-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
import-route
command.
8. Configure IPv6 IS-IS to
filter received routes.
filter-policy
{ ipv6-acl-number |
prefix-list
prefix-list-name |
route-policy
route-policy-name }
import
By default, IPv6 IS-IS does
not filter received routes.
9. Configure IPv6 IS-IS to
redistribute routes from
another routing protocol.
import-route
protocol [ as-number |
process-id ] [
allow-ibgp
] [
allow-direct
|
cost
cost-value | [
level-1
|
level-1-2
|
level-2
] |
route-policy
