Ali,

Can you post the relevant configuration to check it out?

R2 is not becoming part of that "standby 1" group. I in fact can't even ping it any more. debug standby shows this message: HSRP: Fa4 Grp 1 Hello Received when interface down Now if I either reboot it or clear the arp on R2 it starts to work. Any ideas on what could be happening? I am working on a specific situation and in a lab if I shut down the switch port connecting R2 and turn it back on.

You can configure the 10.20.20.x network to work as hsrp on the routers, so the server will see the HSRP VIP address as default gateway. Jack,

If you take the two internal interfaces of the routers (FE0/1) and connect them together with a cross-over cable, how are you going to connect the two routers to the internal LAN? So the answer is no. You must have a LAN switch. Greg,

You can also configure the timers for HSRP for setting interval of hello packets & hold down timers.

#standby 1 timers 5 10
(This means that hello packets will be sent every 5 seconds and the router will wait for 10 seconds before declaring one of the router dead)

In fact, as soon as the first router comes back, this last comes primary again (because it has the higher HSRP priority and the preempt is configured on both ones). You can configure a delay for the preempt to be sure your L2 network is stable before the HSRP changes. For example: preempt delay min 120 (Wait 2 minutes before coming back primary) Regards, Lionel Hi,
