hi! i've 2x 6509 currently running in our LAN with 2x sup engines in each chassis, but i noticed that there are actually 5 "routers" configured in these 4 sup engines, each with the same standby ip on each vlan. I think there are running on hsrp. Just wonder, why are there additional one "router" here.
chassis a (priority of 90 and 110)
chassis b (priority of 120 and 80)
There's additional "virtual"(that's what i think) with priority of 120.
In this case will there be any load balancing between the 4 sup engines/routers? or just 1 in each chassis?
Please advise. Thanks.
