Cisco Routers :: RV042 Not Announcing VPN Routes Over RIP V2

Problem: RV042 is not announcing a class C VPN route via RIP to other routers. It announces the gateway public address via rip, but not the VPN route.
  
I am attempting to use a pair of RV042 as a redundant links between our home office and a branch. The home office and branch is already connected via a T1. Each location also has an additional cable internet connection with public IP address and a cisco 1921 router controlling the traffic.
 
The 1921 routers are using OSPF to route traffic over the T1 and have RIPv2 enabled to talk to their local respective RV042s. Here is a description of how the network is set up.
  
MainRouter - cisco 1921
Eth0 - Network is 192.168.41.0/24
IP address is 192.168.41.20
Eth0/1 - Network 10.1.1.1 255.255.255.254
T1 connection to branch router

[code]....
 
Anyhow I'm thinking a workaround might be to set up a GRE tunnel across those 10.0.X.X subnets to the other side so I can at least dynamically route traffic accross.... Without the RIP routes being announced I don't have automatic failover!
