protocols bgp <asn> parameters bestpath med <action>

Directs the router to compare the multi-exit discriminator (MED) among paths learned from confederation peers during best path selection.

set protocols bgp asn parameters bestpath med { confed | missing-as-worst }
delete protocols bgp asn parameters bestpath med [ confed | missing-as-worst ]
show protocols bgp asn parameters bestpath

By default, when making the best-path selection, the router does not consider the MED.

asn
The number of the AS in which this router resides. The numbers range from 1 through 4294967294. The subrange, 64512 through 65534, is reserved for private AS.
confed
Compare the MED among confederation paths.
missing-as-worst
Treat a missing MED as the least preferred one.
