Enabling Tracking of the CPE-Facing Layer 2 Interface

This topic describes how to configure the VRRP group to track the status of the CPE-facing Layer 2 interface (subnet).


If there is only one Layer 2 interface in the bridge domain, this step is optional. If the only Layer 2 interface is down, the bridge domain is also down, including the IRB interface. This also brings down the VRRP instance.

To enable interface tracking for the VRRP group:

  1. Enable interface tracking for the VRRP group.
  2. Review the configuration.
