Usage
Information
Configuring or un-configuring 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 configured on the router in order 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 will apply 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.
neighbor ebgp-multihop
Attempt and accept BGP connections to external peers on networks that are not directly connected.
