Parameter
med-value: MED value to be specified. The range is 0 to 4294967295. By default, the
med-value is 0.
Description
Use the default med command to configure the default system metric.
Use the undo default med command to restore the default metric of the system.
Multi-Exit Discriminators (MED) attribute is the external metric of a route. Different from
local preference, MED is exchanged between ASs. However, this attribute is
non-transitive. When a router running BGP gets routes with the same destination
address but different next hops from different external peers, it selects the route with
the smallest MED as the optimum route, provided that all other conditions are the
same.
Example
# Routers RTA and RTB belong to AS100 and router RTC belongs to AS200. RTC is
the peer of RTA and RTB. So the MED of RTA can be configured as 25 to allow RTC to
select the route transmitted by RTB first.
[Quidway-bgp] default med 25
