site-to-site ip route crosspost

Sorry for the cross posting, but I am just trying to get this solved
as quickly as possible. Thanks for the help!!!

Hello all. I have recently configured a site-to-site vpn tunnel
between two Cisco 2801 routers. What I am trying to do now is setup a
static route to go over this tunnel.

Network A: Network B:

111.198.5.0 111.198.3.0
255.255.255.0 255.255.255.0

I don't know the correct syntax, but I want to say:

On Router A:
ip route 111.198.3.0 255.255.255.0 over VPN Tunnel

On Router B:
ip route 111.198.5.0 255.255.255.0 over VPN Tunnel

I have tried just specifying the next hop router it will go through,
but it doesn't travel over the tunnel. How do I specify I want all
network traffic (listed above) to go through the VPN tunnel to reach
destination address?
