Re: BGP default route

hahaha ...

I thought your earlier response with this command suggestion was in relation
to the original posting and original question. How to redistribute a
default route from BGP into an IGP?

This command won't help you!

I thought you were answering the original question and email, and so I
thought to myself "hummm ... I should lab this myself!"

I did however, add some iBGP routes between my bgp routers and tested
redistribution with and without this command.

Love it!

There is nothing like doing a lab to gain a greater understanding.

Thanks!

Andrew
