12.7.2 Configuration example
Objective:
Configure L3VPN based on MPLS technology between ESR1 and ESR3. The final result of the configuration is
the appearance of connectivity between nodes connected to the VRF on different routers in the network (i.e.
the union of VRFs on different routers via MPLS transport). In this case, transfer of MPLS service tags for
L3VPN service via MP-BGP and transfer of transport tags to reach nexthop addresses of received BGP routes
must be provided.
