Please log in for more thread options I need some hint I have 2 C26xx running IOS 12.1 with several interfaces which I want to setup in a failover configuration with HSRP The idea is to switch to the backup router if any of the interfaces goes down On main router : interface f0/0 ip address 10.0.0.2 255.255.255.0 standby 1 ip 10.0.0.1 standby 1 preempt standby track f0/1 interface f0/1 ip address 172.16.0.2 255.255.255.0 standby 2 ip 172.16.0.1 standby 2 preempt standby track f0/0 I need some hints because I can't model the configurations Thanks in advance | |||||||||||||

Please log in for more thread options I would also recommend setting a priority on both sides, either to ensure your traffic is being equally shared between core routers, or B because you want one link preferred downstream (presuming all paths are equal). Higher priority wins in this case, opposite of say spantree priorities on vlans. | |||||||||||||

Actually that's an excellent hint. I didn't think of it.

Maybe removing the preempt command on the emain router would be enough but, then I have to be careful when starting the routers. Or maybe I can set the preempt command, just when I want to revert back to the main router. | |||||||||||||

Usually the HSRP tracking feature is used to track the state of WAN interfaces. Is this how you were intending to use it or are you trying to track LAN interfaces. If the later I would discourage you from doing so as you will unnecessarily complicate your operating environment. Perhaps you can share a little more info about both router , i.e the WAN side of things to assist folks in responding to your query. | |||||||||||||
