37.4 Typical BGP/MPLS VPN Configuration Example
37.4.1 Integrated BGP/MPLS VPN Configuration Example
I. Network requirements
z
VPN-A includes CE1 and CE3; VPN-B includes CE2 and CE4.
z
Subscribers in different VPNs cannot access each other. The VPN-target attribute
for VPN-A is 111:1 and that for VPN-B is 222:2.
z
The PEs and P are switches supporting MPLS, and CEs are common layer 3
switches.
Note:
The configuration in this case is focused on:
z
Configure EBGP to exchange VPN routing information between CEs and PEs.
z
Configure OSPF for inter-PE communication between PEs.
z
Configure MP-IBGP to exchange VPN routing information between PEs.
