Configuring Inter-As Ipv6 Vpn - H3C S5500-HI Series Mpls Configuration Manual

Step
11. Apply an IPv6-prefix list for
the peer to filter
received/advertised routes.
12. Specify the preference value
for the routes received from
the peer.
13. Configure BGP updates to the
peer to not carry private AS
numbers.
14. Apply a routing policy for the
peer.
15. Enable route target filtering
for received BGP-VPNv6
subaddress family routes.
16. Configure the local PE as the
route reflector and specify the
peer as the client.
17. Enable route reflection
between clients.
18. Configure a cluster ID for the
route reflector.
19. Create an RR reflection policy.
For information about IPv6 BGP routing features, see Layer 3—IP Routing Configuration Guide.

Configuring inter-AS IPv6 VPN

If the MPLS backbone that carries the IPv6 VPN routes spans multiple ASs, you need to configure inter-AS
IPv6 VPN.

Remarks
Optional.
By default, no IPv6 prefix list is
applied for a peer.
Optional.
0 by default.
Optional.
By default, a BGP update carries
private AS numbers.
Optional.
By default, no routing policy is
applied for a peer.
Optional.
Enabled by default.
Optional.
No route reflector or client is
configured by default.
Optional.
Enabled by default.
Optional.
By default, each RR in a cluster 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 rout
loops.
Optional.
By default, an RR does not filter the
reflected routes.
With an RR reflection policy, only
IBGP routes whose Extended
Communities attribute matches the
specified one are reflected.
By configuring different RR
reflection policies on different RRs,
you can implement load balancing
among the RRs.
