Command Line Reference Guide

To return to the default BGP routing process, use the no bgp bestpath as-path
multipath-relax command.
Defaults Disabled
Command Modes ROUTER BGP
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 Modes ROUTER BGP
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.
bgp bestpath med missing-as-best
During path selection, indicate preference to paths with missing MED (MULTI_EXIT_DISC) over those paths with an
advertised MED attribute.
S5000
Syntax
bgp bestpath med missing-as-best

command.
