Solutions for tunneling RIPV2 updates ?

Hi All,

I have a number of geographically dispersed proprietary routers that only have RFC-compliant RIPV2 as a routing protocol. They send triggered RIPV2 updates to a central Cisco router via WAN connections.

These proprietary routers cannot be replaced by COTS solutions, as their proprietary functionality are needed by my clients.

The WAN topology and configuration being outside my control, I'm searching for solutions that will prevent the RIP updates generated by my equipment from being subjected to the 30-second RIP updates delays at each routing layer of the WAN fabric.

[proprietary router]--{wan fabric}--[central cisco router]

Would adding a Cisco router on the "proprietary" side of the WAN and creating VPN tunnels to the central Cisco router allow me to tunnel the RIPV2 updates without incurring the same delays ?

[proprietary router]--[cisco local router]--{wan fabric}--[central cisco router]

If so, What would be the recommended VPN ? VPLS, L2TP, other ?

Thanks !

Pierre Olivier.
