You're not alone. I had this very same problem about a year ago in a
work-related lab. Then I beat my head against the wall again a couple
weeks ago while revisiting that lab. Hopefully I don't forget again.

Subject: Redistributing BGP Into OSPF

I almost smashed my router on this one.

Task was to redistribute BGP routes into OSPF. Doyle books say simply
type "redistribute bgp as_num subnets" under OSPF and voila - it should
work. It doesn't. Halabi doesn't help either.

Turns out there is a problem redistributing iBGP learned routes into
IGP.
Three hours of troubleshooting later I found the bgp
redistribute-internal command and finally worked.

Just wanted to vent my frustration because the routing bibles only
mention a problem of redistributing too many BGP routes and overwhelming
the IGP.
