-------------------------R5-------------------------------R6-----------------------------------R7----------------
OSPF Area 0 OSPF Area 3 OSPF Area 0

Loopback on R5: 200.0.0.5
Loopback on R6: 200.0.0.6
Loopback on R7: 200.0.0.7

Link between R5 and R6:
150.50.7.5 & 150.50.7.6

Area 0 discontiguous but not allowed to use virtual link.

R5 Loopback in Area 0
R6 Loopback in Area 0

Configured Tunnel between R5 and R6:

int tunn 0
ip unnumbered loopback 0
tunn source 150.50.7.5
tunn des 150.50.7.6

int tunn 0
ip unnumbered loopback 0
tunn source 150.50.7.6
tunn dest 150.50.7.5

The OSPF Neighbor failed to build between R5 and R6 over the tunnel.
Then I configured the virtual link between R5 and R6, OSPF neigbor
relationship built
over the tunnel.

If I run RIP between R5 and R6 then OSPF works fine over the tunnel
and the OSPF area 0 is connected.

Do we have to run another protocol between the discontiguous OSPF Area 0 ?

Thanks
