8.3.7.0 Introduced on the S4810.
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.
C-Series, E-Series, S-Series, Z-Series, S4810
Syntax
bgp bestpath med confed
To disable MED comparison on BGP confederation paths, enter the no bgp bestpath
med confed
command.
