Re: iBGP redistribution into OSPF posted 01/03/2003

Tran is right. The redistribution command only works on the IGP routing table
but not on BGP routing table. If there isn't the > on the BGP route in bgp
routing table, this route wouldn't appear in the igp routing table, and which
of course wouldn't be redistributed into your ospf. Please attach your show ip
bgp and show ip route output next time.

  As I can see, your iBGP route was not marked "best". It due to "next hop" or
"synchronization" problem. If the next hop was fine, you should add the
command "no sync" under BGP configs on R1, I think it will work well.
  The iBGP should look like this:
  * >i160.100.0.0
  not * i160.100.0.0

  Yasser,

  I humbly beg to differ - that is a totally incorrect
  statement to be made. This has worked in my labs
  before, appropriate consideration should be made when
  posting to such 'definitive' statements to a large
  alias. IMHO - it is a great hiccup to put in a real
  lab situation!!!

  As per CCO:

  "bgp redistribute-internal"

  To allow the redistribution of iBGP routes into an
  interior gateway protocol such as IS-IS or OSPF, use
  the bgp redistribute-internal command in router
  configuration mode.

  Sage
