Mark,

I may be taking your statement out of context but let me clarify it anyway.
BGP "default-info originate" does not work the same as with some of the
other routing protocols. BGP will not *create* a default route just because
you use this command (like OSPF can do). There are two ways to get a
default route into the BGP RIB:

1.

router bgp 1
  redist <protocol>
  default-information originate

  (if you leave either statement out it will not go in the RIB)

2.

router bgp 1
  network 0.0.0.0 <-- puts it in the RIB *and* advertises it

But both methods require you to have a 0.0.0.0 route already in
the local routing table.

Chris
