I didn't get how this helps to make this redistribution useful.
Could you give me more hints?

Hi, all

I have a question regarding to redistribute IGR routes into 
BGP. Currently
both Cisco
and Juniper support it.

Here I don't understand what is the advantage of this 
redistribution?
Because BGP is
potentially injecting information into the IGP and then sending such
information back into BGP.

Could anybody provide more description regarding the 
advantage and the
disadvantage
of redistribuing IGP routes into BGP?

Do people use this in real life?

Thanks a lot,
Xingguo
