Layer 3 Routing Commands 1285
Command Mode
BGP Router Configuration mode
User Guidelines
When disabling BGP using no enable, BGP retains its configuration. The no
router bgp command resets all BGP configuration to default values.
When BGP is administratively disabled, BGP sends a NOTIFICATION
message to each peer with a Cease error code.
The no enable command persists in the running-config (and startup-config)
only when a router-id has assigned using the bgp router-id command. If no
router-id has been assigned, the administrative state will not appear in the
running-config or in the startup-config.
Command History
Introduced in version 6.2.0.1 firmware.

are considered part of the same list.
