Cisco 3945 + HSRP-IP SLA issue

vinayjaiswal

Level 3

We have configured HSRP between two cisco 3945 series router.  We also configured IP SLA to track the link.

 

we observed some issue with Track and It is showing down even after that link is up.

 

Sw-2 should be active for hsrp group 1 but when link went down hsrp priority decremented by 20 as per  ip sla/track  so SW-1 became an active for hsrp group -1.

 

now link is up but still sw-1 is active and sw2 is stanby and Track status is showing down.

 

interface GigabitEthernet0/0
 ip address 192.168.19.38 255.255.255.240
 no ip redirects
 no ip unreachables
 duplex auto
 speed auto
 standby 0 ip 192.168.19.36
 standby 0 preempt
 standby 1 ip 192.168.19.46
 standby 1 priority 110
 standby 1 preempt
 standby 1 track 3 decrement 20
 no mop enabled
end

Your post seems to focus on this as an issue with HSRP and you do give us HSRP config from one device. But reading the post it seems that HSRP is doing what it should if track is reporting down and that really the issue here is about track. Please give us the config that includes track as well as HSRP.
