I have 2 4506's are Port Channeled. Today my 3845 is only connect to one of those. I'd like to use HSRP and connect the 3845 to both 4506's, that way my MPLS traffic won't have to traverse the first one to reach it's destination.
Is this possible? Can anyone point me to an article?
Thanks,
Gates

You can't do this because you can't have 2 ip addresses out of the same subnet on the same router.
Do this instead -
3845
int gi0/1 (connected to 4506_1)
ip address 192.168.5.1 255.255.255.252
int gi0/2 (connected to 4506_2)
ip address 192.168.5.5 255.255.255.252
4506_1
int gi0/1 (connected to 3825 gi0/1)
no switchport
ip address 192.168.5.2 255.255.255.252
4506_2
int gi0/1 (connected to 3825 gi0/2)
no switchport
ip address 192.168.5.6 255.255.255.252
then either
1) if you are running a dynamic routing protocol between the 3825 and the 4500s already the 3825 will see 2 equal cost paths to the 4500s and use them both
or
2) if you aren't running a dynamic routing protocol you can just use static routes.

Thanks that makes sense. We are running a dynamic protocol so I should be good there.
Thanks for the response.
