with reference to how BGP select the best route (weight, local pref etc) can someone please clarify or give further explanation on the following:
1) Lowest IGP metric to Next hop (is this not the same as MED)
2) Most Recent Route
Lowest IGP metric to NH is the one which actually sort of least cost path to reach the NH which wud have this peer reach the other BGP peer and evolve in exchange of BGP routes.
MED is one which is actually used to comeinto your bgp router from ur connected BGP peer in different AS.the peer uses MED to direct the router which exit point to take when goin for you peer.
Most recent route indicates d current best path is kept as it is unless there are no drastic changes in other parameters.
Rate if this helps!!!
