Hi everybody,

in order to connect a LAN to 02 redundant routers like the attached diagram, the question is when the port Gi0/1 in 2960 switch is active and Gi0/2 is blocked, all the 03 devices are reachable (respond to ping) and traffic goes through, but when port Gi0/1 is DOWN and the port Gi0/2 is active, the routers are not rechable from 2960 switch and no traffic is possible between switch and routers.

any suggestions ?

Can you post configs of 2 routers and the switch.

Also when you configured HSRP did you make the default-gateway on the switch point to the Virtual IP address you configured under HSRP ?
