Hmm,
Well the reason for rib failed routes is this:
EBGP AD is 20
IBGP AD is of 200
Any other IGP falls between 30 and 200, meaning OSPF, RIP ..et all. Hence
what rib failed routes indicate is that the since there exists a source
which is more relaible than Ibgp advertisments, the routes will be marked as
rib failed routes in the BGP table, and in the routing tables for these rib
failed prefixes you will see routes via other IGP. :)
To fix this one must not advertise these routes, in an AS via BGP .. I mean
local links within an AS are not advertised in BGP, but yes if you want to
send these out of the AS sure use BGP. Mind you rib failed routes do not
indicate that they wont get advertised to EBGP peers.
HTH,
Andy.
