Next-hop Resilience (Shared IP) options for L3 Interfaces

migration — Mon, 19 Sep 2011 12:26:55 GMT

Hi all,

We're preparing a migration from Nokia IP boxes to a pair of PA4050s in an active/passive HA setup. We currently use VRRP on the Nokias for next-hop redundancy but I couldn't find an equivalent option on the Palos.

What options are available to us? Are we going to have to use HSRP from the switch side or can we do something with virtual routers to give us a resilient default gateway for each LAN?

Hi,

configure one of the box, then go to device ->setup to have HA setting in both boxes, then both boxes will run in HA. We only need one IP address for each VLAN for two boxes, and when the active box is failed, the standby box will take the active role and send out GARP to update the next hop devices that now that IP address is hosted by another box.
