Command
History
Version 9.0(1.3) Introduced on the S5000.
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
Enable MULTI_EXIT_DISC (MED) attribute comparison on paths learned from BGP confederations.
S5000
Syntax
bgp bestpath med confed
To disable MED comparison on BGP confederation paths, enter the no bgp
bestpath med confed
command.
Defaults Disabled

Command
History
Version 9.0(1.3) Introduced on the S5000.
Usage
Information
The software compares the MEDs only if the path contains no external
autonomous system numbers. If you enable this command, use the clear ip
bgp * command to recompute the best path.
