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.
