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…

reflector and specify an IPv6 
MBGP peer/peer group as its 
client 

peer { ipv6-group-name | 
ipv6-address } reflect-client
