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 dierent (but equal-length)
autonomous system paths. Without this option, ECMP expects the AS paths to be identical for load-sharing.
bgp bestpath med confed
Enable MULTI_EXIT_DISC (MED) attribute comparison on paths learned from BGP confederations.
Syntax
bgp bestpath med confed
To disable MED comparison on BGP confederation paths, enter the no bgp bestpath med confed
command.
Defaults Disabled
Command Modes ROUTER BGP
