Harbir,
That's the different story.
IGRP and EIGRP are effectively IGP-class protocols.
On the contrary - BGP in most cases runs defaultless - i.e the BGP-speaking
boxes have no defauls - they know where-and-how-to-get-there.
In the typical scenario, BGP is used on the edge of the local/corporate
network - i.e. at
the point where it connects to the real world - i.e. Internet.
IN that case trying to inject any kind of default in BGP, and more, to
EXPORT that knowledge
can create real disaster in Internet. Of course that's the bad idea.
Can you imagine that your leaf network will say to the whole world that it's
DEFAULT ROUTE
FOR ALL AND EVERYTHING IN THIS WOLD, ESPECIALLY FOR ALL THAT HAVE NO
EXPLICIT
ROUTES (or just wrong)?
In that case - using anything like "I'm default" in BGP-world has no sence
at all.
But in IGP-world - that's normal.
You have small network - you have one (or may be 2) outbound connections to
the "BIG WORLD"
In that case you can instruct your IGP-protocol - it can be OSPF, EIGRP,
RIP - what you actually like -
to say "here's default route - send all the stuff that you have-no-idea
where-to-send to this default path"
And it'll work.
Of course in that case you can get some problem with the "sync-no-sync"
dilemma (with your BGP).
But that's another question.
Regards,
Eugene

Subject: BGP default network
Hello Group
Is there a command in BGP like IGRP ip default-network ?
What would be the syntax get a router to inject a default-network to a
neighboring router ?
I know for a default route to a neighbor you do neighbor
#neighbor 192.68.6.1 default-orginate
Thanks
Harbir
