Re: RR & metrics not being propergated to ebgp peer from RR

MED is a non-transitive attribute which means in your case if the CE
learns a path via iBGP you can't pass the MED for that path to an eBGP
peer. If the CE originated the path into BGP itself then it would be
passed to its eBGP peer (PE).
