Configuring an IPv6 MBGP route reflector
To guarantee connectivity between IPv6 multicast IBGP peers, you must make them fully meshed.
However, this becomes impractical when too many IPv6 multicast IBGP peers exist. Using route
reflectors can solve the problem.
The clients of a route reflector should not be fully meshed, and the route reflector reflects the routes
of a client to the other clients. If the clients are fully meshed, you must disable route reflection
between clients to reduce routing costs.
If a cluster has multiple route reflectors, you must specify the same cluster ID for these route
reflectors to avoid routing loops.
To configure an IPv6 BGP route reflector:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter BGP view.
bgp
as-number
N/A
3.
Enter IPv6 MBGP address
family view.
ipv6-family multicast
N/A
4.
Configure the router as a
route reflector and specify an
IPv6 MBGP peer or a peer
group as its client.
peer
{
ipv6-group-name
|
ipv6-address
}
reflect-client
Not configured by default.
5.
Enable route reflection
between clients.
reflect between-clients
Optional.
Enabled by default.
6.
Configure the cluster ID of
the route reflector.
reflector cluster-id
cluster-id
Optional.
A route reflector using its router ID
as the cluster ID by default.
