In Figure 3-3, the following solution is used:
• CE1 and PC1 belong to Site 1 of vpna; CE2 and PC2 belong to Site 2 of vpna.
• EBGP connections are used between PE1 and CE1, and between PE2 and CE2.
• An IBGP adjacency establishes between PE1 and PE2 to transfer VPNv4 routing
information that contains inner labels.
• Both MPLS and LDP are enabled on PE1, P., and PE2.

Route distinguisher The local route distinguisher (RD) is used to
distinguish routes of different VPN instances.
Export VPN target The export VPN target marks the attributes of
exported routes, which must be consistent with the
import VPN target of the remote PE.
Import VPN target The import VPN target marks the attributes of
imported routes, which must be consistent with the
export VPN target of the remote PE.
Binding VPNs and
interfaces The binding of VPNs and interfaces must be
configured in the view of the interface that connects to
CE.
After the interface is bound with VPN, the
configuration of the network layer, for example, IP
addresses, are deleted.
