please find enclosed the diagram, provided by our ISP
we are setting up a second link for the internet failover
looking at the diagram i have questions with the switch failover
if the 2960 switch of the active path fails then
HSRP failover happens. the backup router becomes active.
backup router becomes active and all traffic goes via backup router
IBGP between the primary and backup router fails
so if i am browsing internet and the failover happens, the traffic goes via backup router. what happens to the return traffic? ISP router on the top doesnt know anything about the switch failover. on the internet the return path will still be via the original primary path. the return packets can be dropped once they reach the original primary 2811 router.
what design changes can be made to fix this? or any configuration?
