So as re-hashed before. Two ways to solve:. Make Area 12 NSSA so that type
5 LSA do not propogate and no default route injected. Or do a stub area
with distribute list in filtering out the default route.
access-list 50 deny 0.0.0.0 0.0.0.0
access-list 50 permit any
I forgot the permit at the end, so the ACL does work. What can I say it
was late :)
