If I understand correctly your topology, you only have one router at each site. So, you won't be able to use HSRP. It is only used when there is more than one router on a LAN.

static routing as of now.

I am not sure what should be my standby IP.

The following is the IP on my network.

HO[4500--3640]--WAN----[2600--3550]SO {{ W A N #1 }}

Ip of 4500 : VLAN 150 define with ip

IP of 3640 : ( connected to 4500 )

IP of 3640 : (WAN connected to 2600 - SO )

IP of 2600 : (WAN Connected to 3640 - HQ ]

IP of 2600 : [connected to 3550]

IP of 3550 : [connected to 2600]

For the new WAN link which would be terminated on 4500 the IP range would be

HO[4500]--WAN----[2600--3550]SO {{ W A N #2 }}

IP of 4500 : VLAN 99 configured as

IP of 2600 : [ connected to 4500 at HO ]

AT HO the defaul-gateway for users is, this is the IP address of 4500 at HO.

Based on the above information please can you help in configuring HSRP

I think the best solution will be to add another router and terminate 2nd wan on it. and leave ur 4500 switch between and connect these two router's lan, create hsrp here and change ur user defaul gateway pointing toward this hsrp address.


leave ur default g/w for users as is, and add static route on 4500 wan link with higher admin distance,so if ur wan link fail with 3640 ,it will bring 4500 wan link as primary from backup.
