In our we had 2 cat6506 with msfc2 (catos 6.4(19),) intervlan routing was ok.
But today we're tried to add 2 cat6509 with sup720 for LAN in DC, i've configured int vlan,
all switch i can ping , but ip address (hsrp) for vlan 1 is flaping
for ex: i can ping it with success for about 5min, and then sudenly all is going down , no ping from host to virt. ip,
Could You help or any suggestion?
