ip alias in the redundant setup

[axfalk]

We're trying to setup a redundancy for the 2 ACE modules in the separate 65xx and were wondering if we would need to setup an ip alias address. what is it for anyway?

Thanks..

Hi,

an alias IP is like an HSRP or VRRP address between two routers. It provides a shared IP address between the two redundant ACEs.

It should be used in routed mode as default gateway for the servers or as next-hop for the upstream router to reach the subnets behind the ACE.
