z You need to configure a route policy to define the community attribute, and apply the policy
to outgoing routes.
z For route policy configuration, refer to Route Policy Configuration in the Layer 3 - IP
Routing Configuration Guide.
Configuring an IPv6 MBGP Route Reflector
To guarantee connectivity between IPv6 multicast iBGP peers, you need to make them fully
meshed, but it becomes unpractical when there are too many IPv6 multicast iBGP peers. Using
route reflectors can solve the problem.
Follow these steps to configure an IPv6 BGP route reflector:
To do… Use the command… Remarks
Enter system view system-view —
Enter BGP view bgp as-number —
Enter IPv6 MBGP address
family view
ipv6-family multicast —
Configure the router as a route
reflector and specify an IPv6
MBGP peer/peer group as its
client
peer { ipv6-group-name |
ipv6-address } reflect-client
Required
Not configured by default
Enable route reflection between
clients
reflect between-clients
Optional
Enabled by default
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.
z 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 need to disable
route reflection between clients to reduce routing costs.
z If a cluster has multiple route reflectors, you need to specify the same cluster ID for these
route reflectors to avoid routing loops.
