Hi, I am new to this site and would like to see if anyone can help?
I have to Cisco Routers 1700 and 877, one is used for main MPLS the other a backup, I have set a Virtual IP for both but the issue is one router uses RIP and the other GRP. In the event of failure on the main link not the router my main 1700 router us unable to route to the backup, I need to find away to route between both router using 2 different protocols. Has any body got ideas of doing this?
Thanks.

Not sure I understand... that's the entire point of a routing protocol... to route to another data path when the best one becomes unavailable. When two routing protocols are used, the routing protocol with the lowest administrative distance will be considered first. From http://www.cisco.com/en/US/tech/tk365/technologies_tech_note 09186a0080094195.shtml - this link , here are some administrative distances you might need to know:
External BGP: 20
RIP: 120
Internal BGP: 200

HSRP between the 2 routers, then on backup lan-to-lan vpn with a static route

First of all, I would run a different IGP like EIGRP or OSPF on the two routers. Then redistribure BGP into the IGP.
