I have two routers connected via VSAT, and between then there is many hops of the VSAT equipments that block OSPF hellos.
I have the solution to use tunnels, is there any other way to specify the IP of the neighbor?

Omar

AKAIK - that is not possible. If you are passing from 1 network to another via an IP network in the middle, you will have to encapsulate the multicast hello's. or if the IP network in the middle is already running OSPF - then create a virtual link and piggy back it.

You can specifiy the neighbors by the IP address, however the routers must have routing entries on how to get to the remote site.
The other option is to change the type of interface you are connecting via - NBMA, Point-to-Point etc.

In NBMA, I can specify the neighbor command, is this sufficient?

Sorry - my last post is mis-leading, I had not read you inital post correctly.
Are you planning to create a GRE tunnel across the link that blocks multicast hellos's from OPSF?
If so - you need to define the GRE tunnels as a point-to-point network type.

Not exactly, I want to avoid using the GRE tunnel. and make adjacencies with distant routers.

Fine,
Now I'm sure that I'll need tunnels.
Thanks again Andrew.
