Usage Information
Conguring or un-conguring the command will bring down and bring up the BGP Route Manager, this will
result in tear down and re-establishment of all active sessions.
Link Bandwidth has to be congured on the router in order to tell it to associate Link Bandwidth with
prexes (paths) and/or to use Link Bandwidth in BGP Multipath route selection.
This is done under BGP conguration and is supported per address family – for IPv4 and IPv6 address
families.
The conguration for a particular address family will apply across all VRFs congured.
This command must be performed on the router which is attaching link bandwidth to prexes (typically a
border router) as well as the router which is expected to load share trac proportional to the bandwidth of
the external links.
