Description
Reroute the reverse traffic when there is a link switch for the incoming traffic.
When you configure the enable-reverse-reroute
option
for a security zone, then the packets of each session that has been
initiated from the zone are checked for the change in the incoming
interface. When an incoming packet arrives on an interface that is
different from the one cached in session, the route lookup is performed
for the reverse path, and the preference is given to the interface
on which the packet has arrived when there are ECMP routes available
to the source. Ensure that when you configure enable-reverse-reroute
option, the new interface on which packets arrive must be part of
the same zone as the earlier interface.
You can enable reverse rerouting in hub-and-spoke deployments, where a spoke device uses APBR to re-route the traffic based on the dynamic applications. In such cases reverse re-route can be used on hub device to correctly re-route the reverse traffic.
