1- On the backbone network, if a PE is connect to a CE, VPN instances need to b reconfigured on the PE, and interface on the PE for connecting to the CE must be bound to a VPN instance. After binding an interface to a VPN instance, you must configure the IP address of the interface between PEs, IS-IS configured for PE interworking. PLSA basic capabilities and MPLS LSP are configured for LSP establishment, and MP _IBGP is configured for VPN route exchange VPN routes exchange , LDAP is short for Label Distribution Protocol, and IBGP is short for interior Border gateway protocol.

2-A CE exchange route exchange routers with a PE over External Border gateway Protocol (EBGP. Configure interior gateway protocol (IGP) on the IS-IS+MPLS backbone networking to achieve the interworking between PEs and IP routers.
