: Which "no features"?  I haven't played with zebra yet, but my 
: understanding is that it supports a large subset of the IOS BGP config 
: language including application of route-maps to incoming/outgoing routes, 
: and therefore things like prepending, setting metrics or preference, etc.  
: Am I mistaken?
