Re: OSPF : LSA

hi Narbik,

Good to listen from you .It was very informative for me.
Fo making something clear for me

Can we generalize that
for IGP redist. routes must be in RIB table (routing table)

for BGP redist. prefixes must be bgp table and chosen as the best&valid?

Is that true?

Can we do
