Working on Lab 17 can't find my problem.
Two routers R1 and R2 connect via serial (hdlc). R1 has NAT going on the
interface going toward router R2 (see configs below). R2/R1 neighbor
relationship get's stuck in INIT state as long as IP NAT OUTSIDE is on R1's
interface to R2. Take the IP NAT OUTSIDE out of R1's config and the OSPF
adjacency comes up immediately. Debug on R1 shows it see's hellos coming
from R2. Debug from R2 shows no hellos coming from R1. Configs look
similar to answers from CCBootCamp and can't find anything in the archives.
Just about decided it is a bug but thought I'd see if anyone else has run
into problems with OSPF adjacencies and NAT. Running 11.3(10)T on R2 and
12.0(7)T on R1.
Thanks
Dan
