Context
Do as follows on the MCE.
You need to perform similar configurations on a PE. For details, refer to manuals of
corresponding products.
Procedure
Step 1 Run the system-view command to enter the system view.
Step 2 Run the bgp as-number command to enable BGP and enter the BGP view.
By default, BGP is disabled.
Step 3 Run the ipv4-family vpn-instance vpn-instance-name command to enter the BGP-VPN
instance view.
Step 4 Run the peer ipv4-address as-number as-number command to configure the PE as the peer of
a VPN private network.
Step 5 (Optional) Run the import-route protocol [ process-id ] [ med med | route-policy route-policy-
name ]
*
command to import routes from other routing protocols.
If another routing protocol is run between an MCE and a site in this VPN, you need to perform
this step.

11.5.7 Checking the Configuration
Run the display ip routing-table vpn-instance on the PE, and you can find the routes to the
local VPN.
11.6 MCE Configuration Examples
This section provides several configuration examples of MCE.
11.6.1 Example for Configuring MCE
Networking Requirements
As shown in Figure 11-3, 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 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.
