Example for Configuring BGP VPWS FRR - Asymmetric Access of CEs to PEs

If one CE is single-homed to a PE and another CE is dual-homed to two other PEs, you can configure BGP VPWS FRR for the two CEs to communicate.

Networking Requirements

On the network shown in Figure 1, CE1 is single-homed to PE1, and CE2 is dual-homed to PE2 and PE3. A primary BGP VPWS connection needs to be established between PE1 and PE2, and a secondary BGP VPWS connection needs to be established between PE1 and PE3, so that when the primary path CE1 <-> PE1 <-> PE2 <-> CE2 fails, VPWS traffic can be quickly switched to the secondary path CE1 <-> PE1 <-> PE3 <-> CE2.

Figure 1 Configuring BGP VPWS FRR - asymmetric access of CEs to PEs

  • Interface 1, sub-interface 1.1, interface 2, and interface 3 in this example represent GE 0/1/0, GE 0/1/0.1, GE 0/1/8, and GE 0/1/16, respectively.



Configuration Roadmap

The configuration roadmap is as follows:

  1. Configure a routing protocol on the PEs of the backbone network to ensure IP connectivity and configure basic MPLS functions and LDP.

  2. Configure PEs to exchange VPWS information as BGP peers.

  3. Enable MPLS L2VPN on PEs and create remote BGP VPWS connections between them.

  4. Configure AC OAM detection and notification and enable OAM mapping on PE2 and PE3.

Data Preparation

To complete the configuration, you need the following data:

  • AS number

  • L2VPN instance name

  • L2VPN instance RD and VPN targets

  • CE names and IDs

Procedure

  1. Configure IP addresses.

  8. Verify the configuration.

    After completing the configuration, run the display mpls l2vpn connection interface command on each PE. The command output shows that BGP VPWS connections have been established. The following example uses the command output on PE1.
