Sample loopback on the CAT of 35.50.35.50/24
On R5, run Nat for the eth interface
R5(config)#access-list 10 permit any
R5(config)#ip nat inside source list 10 int
ethernet1/0
R5(config)#int eth1/0
R5(config-if)#ip nat outside
R5(config-if)#int ser1/1
R5(config-if)#ip nat inside
Assuming that R5 is in area0
On R5, add a loopback with a similar network
35.50.35.52
Add this network to OSPF in area 1
Add an area range for 35.50.0.0/16 to OSPF
On R5 add a static route for the 3550 loopback
network.
Because of the area range, all other routers will
receive a 35.50.0.0/16 route. When the ping traffic
reaches R5, it has a more specific route out the
ethernet.
Cat will NOT need ANY routes, as any incoming traffic
will be coming from R5's address via NAT.
