A peer-group is a set of BGP neighbors that shares the same outbound policy, where the inbound policies might be different.
In general iBGP peers receive the same updates all the time, making them ideal for arrangement for a peer group. The main advantage, besides ease of configuration, is the fact that updates are generated only [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=cciethebeginning.wordpress.com&blog=3180786&post=354&subd=cciethebeginning&ref=&feed=1" />]]></description>
