Example
# The two routers RTA and RTB in the same autonomous area use X.25 and Frame
Relay protocols separately to connect with external autonomous areas. The command
can be used to configure the default local preference of RTB as 180 so that the route
via RTB is selected first when the same route goes through RTA and RTB at the same
time.

Parameter
med-value: MED value to be specified. The range is 0 to 4294967295. By default, the
med-value is 0.
Description
Using default med command, you can configure the default system metric. Using
undo default med command, you can restore the default metric of the system.
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.
