Hsrp not working

[pratik_193]

Hi ,

I have a problem, i have configured hsrp for P2P link which is on FE interface. for testing when i shut the primary link, the hsrp priority descreases, but the traffic does not go through secondary link. what could be the issue?

i am attaching the config also:-

Location A - Primary Router

track 11 ip sla 1 reachability
ip sla responder

what could be the issue here?

share show standby when primary link is up and when you shut it.

do your wan link is working fine at secondary link?

Hi shehzad,

Sorry for the late reply..

Below is the output

The hsrp priority decreases, but still the primary router remains active i.e. the hsrp state change does not happen. here is the output:-

#sh standby brief
                     P indicates configured to preempt.
                     |
Interface   Grp  Pri P State   Active          Standby         Virtual IP
Fa0/3/0     10   90  P Active  local           172.29.7.198    172.29.7.196

the priority of interface fa0/3/0 is 110, it does reduce to 90, but still it is active.

What could be the problem here?

Thanks

Hi,

Fa0/3/0     10   90  P Active  local           172.29.7.198    172.29.7.196

The IPs don't correspond to config  snippet you posted ?

Post  show standby command and also output of debug standby when you shut your tracked interface and could you also draw a diagram of your topology .

Regards.

Alain.
