– If you want to keep the original cost for the imported route, you can run the ipv6
import-route { { ripng | isis | ospfv3 } [ process-id ] | direct | bgp } inherit-
cost [ tag tag | route-policy route-policy-name | [ level-1 | level-2 | level-1-2 ] ]

command to import the external routes. When configuring IS-IS to retain the
original cost value of the imported route, the source routes cannot be static.
NOTE
IS-IS will advertise all imported external routes to an IS-IS routing domain by default.
If only some imported external routes need to be advertised, run the ipv6 filter-policy
export command to set a filtering policy.
If an IS-IS device has a small routing table capacity, run the ipv6 import-route limit limit-
number [ threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value ]
{ level-1 | level-2 | level-1-2 } command to set the maximum number of external routes that
can be imported into an IS-IS routing domain.
(Optional) Configure IS-IS to advertise some external routes to an IS-IS routing domain.
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 } export [ protocol
[ process-id ] ]
IS-IS is configured to advertise specified external routes to the IS-IS routing
domain based on the ACL.
Run any of the following commands as required:
– Configure a basic ACL:
a. Run:
quit
Return to the BGP view.
b. Run:
quit
Return to the system view.
c. Run
acl ipv6 { [ number ] acl6-number1 | name acl-name [ number acl-
number2 ] } [ match-order { auto | config } ]
The basic ACL view is displayed.
d. Run
rule [ rule-id ] { deny | permit } [ fragment | source { source-
ipv6-address prefix-length | source-ipv6-address/prefix-length
| any } | time-range time-name | vpn-instance vpn-instance-
name ]
A rule is configured for the basic ACL.
