Just wondering. Can you run hsrp between 2 routers when one router is
on the local network and the other is the isp's router. Thanks

Additionally and ideally, both routers should also have complete
upstream functionality and routing. That way if one fails, the other
has the exact same paths in and out for full network functionality.
If you have hsrp, and .1 fails over to a second router that doesn't
have full connectivity, or still relies on the primary router for
upstream connectivity, then it defeats the purpose of the having hsrp
except for LAN traffic.

Thanks. In the network i am in currently though. I have a 7206 that
has one gige interface connected to a switch. The gige interface has
the following configuration

ip address 53.141.140.1 255.255.255.0
duplex auto
speed auto
media-type rj45
negotiation auto
standby 1 ip 53.141.140.1
standby 1 priority 20
standby 1 preempt

. The 7206 is then connected to an edge switch that has a 100Mb fiber
feed to the provider. It looks like this interface is set to do hsrp
with preemption to the isp's switch. It looks like from what you were
saying this cannot be possible. Is that correct? Having another
router running hsrp in standby group 1 that is not part of the local
network, cannot be done. Thanks

Well, it can't be legit since your IP address on that interface is the
same as the HSRP address. Second, if that router were to drop, then
how is the upstream router even going to be available to respond to .
1, even if they were on the same network. Unless there is something I
am missing, this does not sound like a proper solution. For proper
HSRP, you would need to have two routers, each with an interface in
the same LAN, with say .2 and .3 as their physical addresses, and .1
as the hsrp address. To work properly, all devices should be be
connected to switches with connections to each of the routers. Or
connections to separate switches that each have connections to a
different router. I would need a basic logical diagram, (isp router
<----> isp switch <---->your router) with some IP addresses, and can
probably answer a little clearer.
