Routing under 2 different subnets

I am needing to setup a router to be able to route between 2 different subnets with different masks. The setup i have is as follows.

My routers setup is
RouterNR1
FastEthernet0/0 10.80.0.1 255.248.0.0
FastEthernet0/1 192.168.0.241 255.255.255.0
Serial0/0 10.88.0.2 255.248.0.0

using RIP
network 10.0.0.0
network 192.168.0.0

after this i have 3 more routers, NR2, NR3, and NR4. On NR1 i can ping the router i have the 192 address from using ping 192.168.0.1 however NR2, NR3, and NR4 can not ping 192.168.0.1. How do i get these other router recognize the route to 192.168.0.241.
