2. Configure vpn1 on PE, bind GE1/0/0 and GE2/0/0 with vpn1, and configure OSPF multi-
instances.
3. Configure the cost value on GE2/0/0 on PE and RTA to make OSPF choose link A
preferentially.
4. Configure the IP FRR of the private network on PE.
5. Configure BFD to sense the link status.
Data Preparation
To complete the configuration, you need the following data:
l On PE, the VPN instance name is vpn1, route-distinguisher is 100:1 and VPN-target is
111:1.
l The cost value of GE2/0/0 on PE and RTA is 100.
l The BFD configuration name and BFD session parameters
Procedure
Step 1 Configure the IP address on every interface (omitted).
Step 2 Configure OSPF on CE1, CE2 and RTA (omitted).
After the configuration, CE1, CE2, and RTA can learn the interface addresses from each other.
Take CE1 as an example:
<CE1> display ip routing-table

Step 3 Configure VPNinstance and OSPF multi-instance on PE.
