In the OSPF view of PE2, import the BGP route and advertise the VPN route of PE1 to the MCE.
The OSPF process is used by the MCE and PE2 for the configuration of OSPF multi-instance.
In the BGP view of PE2, import the OSPF route and advertise the VPN route of MCE to PE1.
The OSPF process is used by the MCE and PE2 for the configuration of OSPF multi-instance.
Data Preparation
To complete the configuration, you need the following data:

Procedure
Step 1 Run OSPF on the PEs of the backbone network.
The configuration procedure is not mentioned.
After the configuration, PEs can learn the Loopback1 address of each other.
Take the display on PE2 as an example.
<PE2> display ip routing-table

Step 2 Configure the basic MPLS capability and MPLS LDP on the backbone network and set up an
LDP LSP.
The configuration procedure is not mentioned.

Set up an EBGP adjacency between PE and the connected CE to import the VPN routes to
the VPN routing table of PE.
Configure OSPF multi-instance between MCE and PE2 to exchange VPN routing
information. Configure RIPv2 between MCE and CE3, and between MCE and CE4, to
exchange VPN routing information.
NOTE
When configuring OSPF multi-instance between MCE and PE2, you need to perform the following
operations.
A VPN instance for each isolated service is created on PE1, PE2 and MCE. Note that the
VPN targets of different VPN instances differ from each other and the VPN targets of the
same VPN instance are identical.
The OSPF data needs to be configured. For different OSPF multi-instances, the OSPF
process IDs must be different.
The RIP processes used to import VPN routes of CE3 and CE4 to MCE need to be
configured. The RIP processes use different process IDs.
