Users Guide

VRRP subscribes to a track object which tracks the interface line protocol state. It uses the tracked object status to determine the priority
of the VRRP router in a VRRP group. If a tracked state or interface goes down, VRRP updates the priority based on how you congure the
new priority for the tracked state. When the tracked state comes up, VRRP restores the original priority for the virtual router group.

Interface tracking
You can create an object that tracks the line-protocol state of an L2 interface, and monitors its operational up or down status. You can
congure up to 500 objects. Each object is assigned a unique ID.
When the link-level status goes down, the tracked resource status is also considered Down. If the link-level status goes up, the tracked
resource status is also considered Up. For logical interfaces such as port-channels or VLANs, the link-protocol status is considered Up if any
physical interface under the logical interface is Up.
The list of available interfaces include:
• ethernet — Physical interface
