Allow an inbound route for OSPF
Allow an inbound route for OSPF

We need this because on router A we have different set of connected routes than
on router B, and OSPF will not advertise the source when it redistributes, so
router B won't know of the connected routes on router A.

Note: We are protecting announcements by means of the loopbacks_and_connected() filter.
