CLI Guide

Usage Information The bestpath router bgp configuration mode command changes the
default bestpath selection algorithm. The multipath-relax option allows load-
sharing across providers with different (but equal-length) autonomous system
paths. Without this option, ECMP expects the AS paths to be identical for load-
sharing.
bgp bestpath med confed

Syntax
bgp bestpath med confed
To disable MED comparison on BGP confederation paths, enter the no bgp
bestpath med confed command.
