Hi,

You can implement HSRP (Hot Standby Routing Protocol) which it is similar to active/standby failover mode in ASA world; there is one router "active" and one router in standby..if the active "dies" the standby take the role of active.

Here is a link for configuring HSRP: http://www.cisco.com/en/US/docs/ios/ipapp/configuration/guide/ipapp_hsrp.html

HSRP is Cisco proprietary. If you want use a standard with functionality similar, but not equal, to HSRP, you must choose VRRP. Here is a link: http://www.cisco.com/en/US/docs/ios/ipapp/configuration/guide/ipapp_vrrp.html

If you want a protocol similar to active/active failover mode in ASA world you have to use GLBP (Gateway Load Balancing Protocol). Here is the link: http://www.cisco.com/en/US/docs/ios/ipapp/configuration/guide/ipapp_glbp.html#wp1054488

I hope this helps.

Best regards.

Massimiliano.
