[c-nsp] OSPF Conditional Inject

[Calin C.]

Hello,

When you're using Ethernet between R1-R2, and you shutdown the interface on
R1, what's happening with the 192.168.12.0/24 on R2? You still have the
subnet in the routing table?
What about the Ethernet interface on R2? Still up?

The idea is that if this is not a p2p connection but rather something like
R1 - L2_Device - R2, for R2 the interface will never go down, so the subnet
will be in the routing table. As long as the subnet it's in the routing
table the condition is meet and the default route is propagated to R3.

Cheers,
Calin
