Configure route reflector
# Configure Router C as a route reflector, Router B and Router D as its clients.
[RouterC-bgp-af-ipv6] peer 101::2 reflect-client
[RouterC-bgp-af-ipv6] peer 102::2 reflect-client
Use the display bgp ipv6 routing-table command on Router B and Router D
respectively, you can find both of them have learned the network 1::/64.
6PE Configuration Network requirements
■
Routers PE 1 and PE 2 support 6PE;
■
Routers CE 1 and CE 2 support IPv6;
■
Between the PE routers is the IPv4/MPLS network of an ISP. The two PEs
establish an IPv4 IBGP connection in between, and the IGP used is OSPF.
■
The CEs reside in IPv6 networks. A CE and a PE use IPv6 link-local addresses to
exchange routing information via a static route;
