2.5 MCE Configuration Examples
This section provides several configuration examples of MCE.
2.5.1 Example for Configuring MCE
Networking Requirements
As shown in Figure 2-2, the networking is as follows:
l CE1, CE2, CE3, and CE4 are edge devices of the VPN.
l CE1 and CE3 belong to a VPN instance named vpnb, and CE2 and CE4 belong to a VPN
instance named vpna.
l PE1 and PE2 are edge routers of the backbone network. BGP or MPLS IP VPN is configured
on the backbone network between PE1 and PE2.
l The MCE functions as a Multi-VPN-Instance CE located in the user network.
l RIP is run between the MCE, CE3, and CE4.
l OSPF is run between the MCE and PE2.
It is required that route isolation between VPNs be implemented on the MCE and routes of VPNs
be advertised to the PE2 through OSPF.
