Step Command 1. Enter system view. system-view 2. Enter BGP view. 3. Enter IPv6 MBGP address family view. 4. Advertise the COMMUNITY attribute to an IPv6 MBGP peer or a peer group. bgp as-number ipv6-family multicast peer { ipv6-group-name | ipv6-address } advertise-community 5. Advertise the extended peer { ipv6-group-name | community attribute to an IPv6 ipv6-address } MBGP peer or a peer group. advertise-ext-community 6. Apply a routing policy to routes sent to an IPv6 MBGP peer or a peer group. peer { ipv6-group-name | ipv6-address } route-policy route-policy-name export Remarks N/A N/A N/A By default, no COMMUNITY attribute is advertised to any peer group/peer. By default, no extended community attribute is advertised to any peer or peer group. Not configured by default. NOTE: You must configure a routing policy to define the COMMUNITY attribute, and apply the policy to outgoing routes. 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 1. Enter system view. system-view 2. Enter BGP view. bgp as-number 3. Enter IPv6 MBGP address family view. ipv6-family multicast 4. Configure the router as a route reflector and specify an IPv6 peer { ipv6-group-name | MBGP peer or a peer group ipv6-address } reflect-client as its client. 5. Enable route reflection between clients. reflect between-clients 6. Configure the cluster ID of the route reflector. reflector cluster-id cluster-id Remarks N/A N/A N/A Not configured by default. Optional. Enabled by default. Optional. By default, a route reflector uses its router ID as the cluster ID. 358
