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
