Configuring an IPv6 MBGP route reflector
To guarantee connectivity between IPv6 multicast IBGP peers, you must make them fully meshed.
However, this becomes unpractical 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.
By default, a route reflector uses its
router ID as the cluster ID.
