Hi,

Plz explain what do u want to achieve. How many wan links do u have ? If you have two WAN links . You can terminate one on each router and add a switch on the Lan side of routers. Now ur LAN network and two Ethernet port of the two routers are on one L2 segment & L3 subnet, they can speak to each other.

refer to the link..

http://www.cisco.com/en/US/docs/ios/ipapp/configuration/guide/ipapp_hsrp.html

You need a Virtual IP from the same subnet as that of the LAN and Lan ports.

COnfige-wise you just need to define teh Virtual ip and standby ( hsrp) group id. Increase the priority of the Primary/Master router Ethernet port to 105. This is minimum required. The virtual IP of the HSRP will be the gateway for yor LAN network.

HTH,

thnks for the conf gi fiel.

But all my host and server are configure with the default gateway as 172.16.0.10 .And the Sstandby 1 priority 105 is ame on both the router . Do i have to change the ip address of gatewate of all the host to 172.16.0.1 .

please advise

This is no big deal. You can change the virtual ip address to 172.16.0.10 instead of 172.16.0.1. Also configure the priority of the active router to higher side than standbay router.

Yes just point both standby and active routers to virtual interface, just set your hosts computers to ip address of virtual router which will act as your gateway device
