• To implement exchange of sub-VPN routes between customer PEs and service provider PEs,
MP-EBGP peers must be established between service provider PEs and customer CEs.

Configuration procedure
1. Configure MPLS L3VPN on the service provider backbone. Use IS-IS as the IGP protocol, enable
LDP, and establish an MP-IBGP peer relationship between PE 1 and PE 2:
# Configure PE 1.
