bgp bestpath med confed <--- enables MED comparison among paths learned from
confederation peers
bgp bestpath as-path ignore <---- basically just ignores the as-path length
during best route calculation
bgp always-compare-med <--- compare meds from neighbors not in the same
external AS
bgp bestpath compare-routerid <-- by default, ebgp won't use router-id as
the last tie-breaker in it's route selection criteria, with this the path
learned first is used, if you turn this feature on, it'll use the routerid
as the tiebreaker.
hope that helps.

when do we use the below commands and why?
bgp bestpath compare-routerid
bgp always-compare-med
bgp deterministic med
bgp bestpath as-path ignore
bgp bestpath med confed
I read through the CCO many times, but i didn't get a clear idea. so can any
body good in BGP explain more?
