High Availability InterSite

Hi,

I need to configure high availability between two sites, today the traffic to Internet from the network A is routed to CoreA, then the CoreA send the traffic to Router A and through a static default route the traffic is sent to Internet. Now a new site is incorporated to the Network A. The RouterB has a default route to InternetB. How I can enable high availability between the site A and site B, for example if the RouterA fail, the traffic from the network must be routed to RouterB, the same scene for the network B, if the RouterB fail, the traffic from the network B must be routed to RouterA. Which feature I can configure? The RouterA and RouterB are Cisco2800 and the Core´s are 3750 with EnhancedImage.

Hi

You can configure OSPF on all 4 devices in area 0 and configure OSPF to advertise default-route from both RTA and RTB

Thank you
