Step Command Remarks
5. (Optional.) Configure filtering
of received routes.
filter-policy { acl6-number |
prefix-list ipv6-prefix-name }
import
By default, the PE does not filter
received routes.
6. Configure ACL-based route
filtering for the specified peer
or peer group.
peer { group-name | ip-address }
filter-policy acl6-number { export |
import }
By default, no ACL-based route
filtering is configured.
7. Configure IPv6 prefix
list-based route filtering for the
specified peer or peer group.
peer { group-name | ip-address }
prefix-list ipv6-prefix-name
{ export | import }
By default, no IPv6 prefix list-based
route filtering is configured.
8. Specify a preferred value for
routes received from the peer
or peer group.
peer { group-name | ip-address }
preferred-value value
The default preferred value is 0.
9. Configure BGP updates sent
to the peer to carry only
public AS numbers.
peer { group-name | ip-address }
public-as-only
By default, a BGP update carries
both public and private AS
numbers.
10. Apply a routing policy to
routes advertised to or
received from the peer or peer
group.
peer { group-name | ip-address }
route-policy route-policy-name
{ export | import }
By default, no routing policy is
applied for a peer.
11. Enable route target filtering
for received BGP-VPNv6
routes. policy vpn-target
By default, route target filtering is
enabled.
12. Configure the local PE as the
route reflector and specify the
peer as the client.
peer { group-name | ip-address }
reflect-client By default, no route reflector or
client is configured.
13. Enable route reflection
between clients.
reflect between-clients
By default, route reflection
between clients is enabled.
14. Configure a cluster ID for the
route reflector.
reflector cluster-id { cluster-id |
ip-address }
By default, an RR uses its own
router ID as the cluster ID.
If more than one RR exists in a
cluster, use this command to
configure the same cluster ID for all
RRs in the cluster to avoid routing
loops.
15. Configure filtering of reflected
routes.
rr-filter
extended-community-number
By default, an RR does not filter
reflected routes.
Only IBGP routes whose extended
community attribute matches the
specified community list are
reflected.
By configuring different filtering
policies on RRs, you can implement
load balancing among the RRs.
Configuring inter-AS IPv6 VPN
If the MPLS backbone spans multiple ASs, you must configure inter-AS IPv6 VPN.
