I have a pair of 3945 routers. Each router has a SM-ES3G-16-P 16-port switch L2/L3 card. I need basic L2 switch (or port channel between each router via these switch port cards.
I need to set up HSRP between a GE port on each router to an external firewall using static routing. I want to set up resiliency between these router GE ports that directly connect to the firewalls so that if Router 1/Firewall 1 fails, router 2/firewall2 takes over. Right now, each router thinks it is the active HSRP on their respective GE, since no HSRP keep alives are communicated between the routers (yet). Hopefully, by establishing a L2/Port-channel between the switch cards, HSRP keep alives will pass between routers. (FWs act as clustered pair using a HSRP IP address for the active FW)
I also have a pair of HWIC-4ESW cards being shipped out next week to try in lieu of those SM-ES3G-16-P cards.
Any suggestions how to get 2 routers communicating HSRP keep alives acess a pair of embedded L@ switch cards on the routers?
