FIGURE 35 Short-path forwarding
If you enable short-path forwarding in both master and backup VRRP-E devices, packets sent by Host Server 1 (in the figure) and
destined for the Internet cloud through the device on which a VRRP backup interface exists can be routed directly to the VRRP backup
device (blue dotted line) instead of being switched to the master router and then back (red dotted-dash line).
In the figure, load-balancing is achieved using short-path forwarding by dynamically moving the virtual servers between Host Server 1
and Host Server 2.
Short-path forwarding with revert priority
Revert priority is used to dynamically enable or disable VRRP-E short-path forwarding.
If short-path forwarding is configured with revert priority on a backup router, the revert priority represents a threshold for the current
priority of the VRRP-E session. When the backup device priority is higher than the configured revert priority, the backup router is able to
perform short-path forwarding. If the backup priority is lower than the revert priority, short-path forwarding is disabled.
