Hi ,
I have a simple HSRP connection with 2 routers , 2 switches for redundancy.
Both the routers are used for load balancing instead of just one being Active HSRP and the other Standby.
For ROUTE1 , Router1 acts as Active and Router 2 Standby
For ROUTE2 , Router2 acts as Active and Router1 Standby
Problem is , HSRP standby state on both the routers keeps changing every now and then.
These are the messages I see on both the routers :
Router1 :
Jun 25 14:31:02 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Standby -> Active
Jun 25 14:31:03 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Active -> Speak
Jun 26 09:49:45 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Standby -> Active
Jun 26 09:49:45 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Active -> Speak
Jun 28 10:07:27 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Standby -> Active
Jun 28 10:07:27 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Active -> Speak
Jul 2 09:39:45 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Standby -> Active
Jul 2 09:39:45 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Active -> Speak
Jul 2 09:56:01 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Standby -> Active
Jul 2 09:56:34 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Active -> Speak
Jul 2 11:48:50 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Standby -> Active
Jul 2 11:48:51 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 15 state Active -> Speak
ROUTER2 :
Jul 2 09:39:44 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Standby - > Active
Jul 2 09:39:45 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Active -> Speak
.Jul 2 09:55:59 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Standby -> Active
.Jul 2 09:56:01 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Active - > Speak
Jul 2 11:07:15 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Standby - > Active
Jul 2 11:07:16 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Active -> Speak
Jul 2 11:48:50 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Standby - > Active
Jul 2 11:48:51 BST: %HSRP-6-STATECHANGE: FastEthernet0/1 Grp 10 state Active -> Speak
Any idea why this is happening.
Thanks in advance.

Hi
Have u checked the link between the routers,is it working fine.
If can post the config we can check whats going on.
Normally this may be caused due to improper exchange of hello messages between the devices.
Thanks

Thanks Mahmood.
Ya , I have checked the physical connections.No issues with it.
Configs :
ROUTER1 :
int fa0/0
standby 15 ip
standby 15 priority 150
standby 15 preempt
standby 15 track FastEthernet1/1 90
int fa0/1
standby 10 ip
standby 10 preempt
ROUTER2 :
Int fa0/0
standby 10 ip
standby 10 priority 150
standby 10 preempt
standby 10 track FastEthernet1/0 90
int fa0/1
standby 15 ip
standby 15 preempt
Thanks.

It feels that the hello packets are getting missed between the routers.
Check for errors on the switch ports where the routers are connected. Make sure there are no duplex issues.
Try chnaging the switchports a well

Checked the Switches for interface errors , speed/duplex mismatch , logs - everything normal.
