NOTE
IS-IS will advertise all imported external routes to the IS-IS areas by default.
If only some imported external routes need to be advertised, run the ipv6 filter-policy
export command to set a filtering policy.
l (Optional) Configure IS-IS to advertise some external routes to the IS-IS areas.
1. Run:
system-view
The system view is displayed.
2. Run:
isis [ process-id ]
The IS-IS view is displayed.
3. Run:
ipv6 filter-policy { acl6-number | acl6-name acl6-name | ipv6-prefix ipv6-
prefix-name | route-policy route-policy-name } export [ protocol [ process-
id ] ]
IS-IS is configured to advertise specified external routes to the IS-IS areas.
NOTE
After this command is run, only external routes that meet the specified conditions can be
advertised to the IS-IS areas.

6.14.5 Checking the Configuration
After IS-IS is enabled to import routes from other protocols, run the following commands to
verify that the configurations are correct.
Procedure
l Run the display isis lsdb [ { level-1 | level-2 } | verbose | { local | lsp-id | is-name symbolic-
name } ]
*
[ process-id | vpn-instance vpn-instance-name ] command to check IS-IS LSDB
information.
l Run the display isis route [ process-id | vpn-instance vpn-instance-name ] [ ipv6 ]
[ verbose | [ level-1 | level-2 ] | ipv6-address [ prefix-length ] ]
*
command to check IS-IS
routing information.
l Run the display ipv6 routing-table ipv6-prefix ipv6-prefix-name [ verbose command to
check the IP routing table.
