therefore, it immediately enters active state at Mar 8 20:34:30.221. From that point on, the active router sends its active state hello message every 3 seconds. Because there are no other routers on this broadcast domain, no hellos are being received. 1DSW1(config)#interface vlan 11

Router 1DSW1 is not configured with preempt, so even though it has a higher priority, it does not immediately become the active router. After router 1DSW1 goes through the HSRP initialization states, it will come up as the standby router. 1DSW1(config)#interface vlan 11
