routing failover issue

[wajid dabir]

My HUB location have the two router and Two WAN link,one on each.spoc location also have the same thing.

1.In HUB location for LAN we are using a HSRP and at spoc location also we are using HSRP for LAN.

2.for primary router i am using a BGP protocol and static for secondary.

my doubt is how do the failover between two hsrp will work.

when the primary link goes down,standby will become the active at HUB side,but at spoc location there is no change in router state.so the traffic from the HUB active router to spoc standby router will follow and it is not reach to spoc end.

kindly help me for this....

Hi

The possible solution would be to enable tracking on the ip address reachability of remote site which is learned through BGP. so once primary link goes down on either side other side will not be able to reach the peer end IP address and will trigger the HSRP failover by decrementing the priority.

Below are the command reference:

(Conf)# track 1 ip route 15.0.0.0 255.255.255.0 reachability

(Conf-if) standby 1 track 1 decrement 60

Hope this will resolve your problem. Please feel free to contact in case you need any further assistance.

Thanks & Regards
