with identical destination address and different next-hops from various external
peers, it will select the best route depending on the MED value. In the case that all
other conditions are the same, the system first selects the route with the smaller
MED value as the external route of the autonomous system.
Example
Routers RTA and RTB belong to AS100 and router RTC belongs to AS200. RTC is
the peer of RTA and RTB. The network between RTA and RTC is X.25 network and
the network between RTB and RTC is Ethernet. So the MED of RTA can be
configured as 25 to allow RTC to select the route transmitted by RTB first.
