[c-nsp] GRE question ..OSPF equal path

[Vikas Sharma]

Hi Arie,

Thanks for the reply.

Inline with the below mail, how can I force OSPF to use certain path (e.g.
If-1) to establish GRE tunnel when router have two equal cost path available
i.e If-1 and If-2 has the same cost and my requirement is to create GRE
tunnel through If-1 always. This is my requirement though looks strange.

We have OSPF running in the network

Regards
