Usage Information
Configuring or un-configuring the command brings down and brings up the BGP
Route Manager, this results in tear down and re-establishment of all active
sessions.
Link Bandwidth has to be configured on the router to tell it to associate Link
Bandwidth with prefixes (paths) and/or to use Link Bandwidth in BGP Multipath
route selection.
This is done under BGP configuration and is supported per address family – for
IPv4 and IPv6 address families.
The configuration for a particular address family applies across all VRFs configured.
This command must be performed on the router which is attaching link bandwidth
to prefixes (typically a border router) as well as the router which is expected to load
share traffic proportional to the bandwidth of the external links.
