I'm trying to track a WAN interface with HSRP.
Router HSRP config. is as follows.
Active Router(GW01)
-------------------
interface FastEthernet0/0.20
encapsulation dot1Q 20
ip address 2.2.2.2 255.255.255.0
standby 1 ip 2.2.2.1
standby 1 priority 105
standby 1 preempt delay minimum 60
standby 1 track Serial0/0
Standby Router(GW02)
--------------------
interface FastEthernet0/0.20
encapsulation dot1Q 20
ip address 2.2.2.3 255.255.255.0
standby 1 ip
standby 1 preempt
-----------------
Active router sends a lower priority (95) as soon as it tracks the failure of the WAN interface.
I see the following HSRP debug messages(debug standby on Active router) saying that the coup was ignored.
GW01: Sep 1 15:04:31: HSRP: Fa0/0.20 Grp 1 Hello out 2.2.2.2 Active pri 95 vIP 2.2.2.1
GW01: Sep 1 15:04:31: HSRP: Fa0/0.20 Grp 1 Coup in 2.2.2.3 Standby pri 100 vIP 2.2.2.1
GW01: Sep 1 15:04:31: HSRP: Fa0/0.20 Grp 1 Ignoring Coup (100/2.2.2.3 < 105/2.2.2.2)
What does this actually mean and why does it happen?
Many thanks for sharing your ideas and experiences.

Hi
U need to include below
standby 1 track Serial0/0 20
i.e how much u want the priority to be decreased when the serial0/0 goes down.
Thanks

Hi,
According to my understanding the default(10) would be good enough to achieve the required functionality.

Hi
interface FastEthernet0/0.20
encapsulation dot1Q 20
ip address 2.2.2.3 255.255.255.0
standby 1 ip
standby 1 preempt
according to u r config u r missing the
standby 1 ip
or its a typo.
Thanks

You don't need to have it specified manually.
The standby router can learn it from the Active router.
Here's the corresponding output of show standby fyi.
FastEthernet0/0.20 - Group 1
State is Standby
Virtual IP address is 2.2.2.1 (learnt)
Note that it is learnt from the active HSRP router.
