Configuration
for Router B
Because Router B is the PE router for the end customer
CE router (Router A), you need to configure a routing instance (vpna). Configure the labeled-unicast statement on the
IBGP session to Router D, and configure family-inet-vpn for
the IBGP session to the other side of the network (see Figure 53) with Router I:
