463NOTE:You must configure a routing policy to define the COMMUNITY attribute, and apply the policy to outgoingroutes.Configuring an IPv6 MBGP route reflectorTo 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 reflectorscan solve the problem.The clients of a route reflector should not be fully meshed, and the route reflector reflects the routes of aclient to the other clients. If the clients are fully meshed, you must disable route reflection between clientsto reduce routing costs.If a cluster has multiple route reflectors, you must specify the same cluster ID for these route reflectors toavoid routing loops.To configure an IPv6 BGP route reflector:Step Command Remarks1. Enter system view. system-view N/A2. Enter BGP view. bgp as-number N/A3. Enter IPv6 MBGP addressfamily view. ipv6-family multicast N/A4. Configure the router as a routereflector and specify an IPv6MBGP peer or a peer groupas its client.peer { ipv6-group-name |ipv6-address } reflect-client Not configured by default.5. Enable route reflectionbetween clients. reflect between-clients Optional.Enabled by default.6. Configure the cluster ID of theroute reflector. reflector cluster-id cluster-idOptional.By default, a route reflector uses itsrouter ID as the cluster ID.Displaying and maintaining IPv6 MBGPDisplaying IPv6 MBGPTask Command RemarksDisplay IPv6 MBGP peer groupinformation.display bgp ipv6 multicast group [ ipv6-group-name ] [ |{ begin | exclude | include } regular-expression ]Available inany viewDisplay IPv6 MBGP routinginformation injected with thenetwork command.display bgp ipv6 multicast network [ | { begin | exclude| include } regular-expression ]Available inany view
