Whta is the configuration on routers/Switches ? Lets say router A: Int Fa0/0 standby 1 ip 10.10.10.1 Standby 1 priority 110 standby 1 preempt -------------------------- Router B: int fa0/0
standby 1 ip 10.10.10.1 standby 1 preempt Switch A & B configured with ip defualt-gateway 10.10.10.1 and if you have proper cabling done with both routers then layer 2 switches should be able to pass traffic to active/standby routers wiht out any problem ? I think it should work with this configuration. Please correct me if I misunderstood anything Thanks Nilesh On Mon, Jan 24, 2011 at 11:09 PM, Andres Villalva <[email protected]>wrote: > Hi Nitin, > > The switch itself doesn't know.
