I've been playing around with a very basic HSRP Preempt configuration and I can't get my Standby switch to take over as the active. Here's the scenario:
Switch 1 is the Active, with Priority set at 105.
Switch 2 is the Standby, with Priority left at default (100). Preempt is configured on Switch 2.
When both switches are up and operational, the Standby group looks good. For example, when I do a show standby on Switch 1 I get the following:
Vlan100 - Group 1
State is Active
2 state changes, last state change 00:25:51
Virtual IP address is 10.10.10.3
Active virtual MAC address is 0000.0c07.ac01
Local virtual MAC address is 0000.0c07.ac01 (v1 default)
Hello time 3 sec, hold time 10 sec
Next hello sent in 0.704 secs
Preemption disabled
Active router is local
Standby router is 10.10.10.2, priority 100 (expires in 10.512 sec)
Priority 105 (configured 105)
Group name is "hsrp-Vl100-1" (default)
So if I power down Switch 1, the HSRP and the preemption that I configured on Switch 2 should cause it to take over as the Active switch, correct? But when I power down Switch 2 and then do a show standby on Switch 2, I only get the following:
Switch2#show standby
Vlan100 - Group 1
State is Init (interface down)
6 state changes, last state change 00:00:26
Virtual IP address is 10.10.10.3
Active virtual MAC address is unknown
Local virtual MAC address is 0000.0c07.ac01 (v1 default)
Hello time 3 sec, hold time 10 sec
Preemption enabled
Active router is unknown
Standby router is unknown
Priority 100 (default 100)
Group name is "hsrp-Vl100-1" (default)
Am I doing something wrong? Why does Switch 2 not take over as the Active switch? For your reference, here are the HSRP configs on both Switch 1 and Switch 2:
Switch 1:
interface Vlan100
ip address 10.10.10.1 255.255.255.0
standby 1 ip 10.10.10.3
standby 1 priority 105
Switch 2:
interface Vlan100
ip address 10.10.10.2 255.255.255.0
no ip route-cache
standby 1 ip 10.10.10.3
standby 1 preempt
Any insight is appreciated, thanks.
