Hi
I'm configuring HSRP on two external routers, each of which connects to a provider (the same provider but different sites). The idea is that should one link fail, the other router will take over. I'm using a track 1 rtr reachability statement to basically failover when we can't ping a particular provider IP address.
So, it's all standard stuff but here is the problem...I can only ping the provider IP on router A using the source address of the HSRP virtual address. When the router A becomes the standby router, it can no longer ping as the HSRP IP address now belongs to router B.
As it can no longer ping, the track statement fails and it never becomes the active router again.
Is there a way around this or am i doing something silly?
Router A
int x/x
ip address x.x.x.241
standby ip x.x.x.243
standby preempt
standby priority 110
standby track 1
track 1 rtr 1 reachability
ip sla 1
icmp-echo x.x.x.244 source-ip x.x.x.243
ip sla schedule 1 life forever start-time now
Router B
int x/x
ip address x.x.x.242
standby ip x.x.x.243
standby priority 105

Well, the way round it is to ping from the physical addresses.
When you say you can only ping from the VIP is that a requirement on you or does it just not work when you try with the physical addresses ? If it doesn't work then you should be looking at why because there is no reason, unless the provider is blocking those addresses why it should not be able to ping.

Can you post a diag? I'd like to get a clearer picture of what you're doing.
Cheers!

Well, I've worked out a workaround. I wanted to ping a certain IP to tie in with other things I'm doing but I realised I don't actually have to, I can track the status of the interface in this instance.
I still can't ping from the physical interface IP address, only the VIP, but it's not a problem now.
Thanks

Great that you have found a workaround.
Still, this is no reason to not-rate the answers you received.

Sorry, but I'm not sure how to rate them!? There's no way to do on reply and the stars are greyed out.
