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.

bgp enforce-first-as

Disable (or enable) enforce-first-as check for updates received from EBGP peers.
