This command globally enables BGP, while retaining the configuration. BGP is enabled by default once you specify the local AS number with the router bgp command and configure a router ID with the bgp maxas-limit command. When you disable BGP, BGP retains its configuration. If you invoke the no router bgp command, all BGP configuration is reset to the default values.
When BGP is administratively disabled, BGP sends a Notification message to each peer with a Cease error code.
