The IPv4 VRRP backup group is associated with EFM.
NOTE
For 10GE LAN and 40GE interfaces, when 802.3ah is configured and the peer end cannot receive optical
signals but can transmit optical signals properly, no Remote Fault packets are sent. The local trunk interface
cannot detect a Down switching event. In this situation, the backup function cannot provide protection.
When 802.3ah is also configured, you can run the
efm trigger if-down
command to associate an interface
Down event.

4.4.5 Associating a VRRP Backup Group with Routes
A VRRP backup group can be associated with routes. This ensures consistent routes for network-
to-user and user-to-network traffic.
