View

Default level
2: System level
Parameters
med-value: Specifies the default MED value, in the range of 0 to 4294967295.
Description
Use default med to specify the default MED value.
Use undo default med to restore the default.
By default, the default med-value is 0.
The multi-exit discriminator (MED) is an external metric of a route. Different from the local preference, the
MED is exchanged between ASs and stays in the AS after it enters the AS. The route with a lower MED
is preferred. When a router running BGP obtains several routes with an identical destination but different
next-hops from various external peers, it selects the best route depending on the MED value. If all the
other conditions are the same, the system selects the route with the lowest MED as the best external route.
Examples
# Devices A and B belong to AS100 and device C belongs to AS200. Device C is the peer of A and B.
Configure the MED of A as 25 to make C select the path from B.
