Activating and disabling BGP4
BGP4 is disabled by default. To enable BGP4 and place your BigIron RX into service as a BGP4
router, you must perform the following required steps.
1. Enable the BGP4 protocol.
2. Set the local AS number.
3. Add each BGP4 neighbor (peer BGP4 router) and identify the AS the neighbor is in.
4. Save the BGP4 configuration information to the system configuration file.
For example, enter commands such as the following.
BigIron RX> enable
BigIron RX# configure terminal
BigIron RX(config)# router bgp
BGP4: Please configure 'local-as' parameter in order to enable BGP4.
BigIron RX(config-bgp)# local-as 10
BigIron RX(config-bgp)# write memory
The router bgp command enables the BGP4 protocol.
(For information on the local AS number, refer to
NOTE
By default, the Brocade router ID is the IP address configured on the lowest numbered loopback
interface. If the device does not have a loopback interface, the default router ID is the lowest
numbered IP interface address configured on the device. For more information, refer to
the router ID"
NOTE
When BGP4 is enabled on a BigIron RX, you do not need to reset the system. The protocol is
activated as soon as you enable it. Moreover, the router begins a BGP4 session with a BGP4
neighbor as soon as you add the neighbor.

Note regarding disabling BGP4

If you disable BGP4, the BigIron RX removes all the running configuration information for the
disabled protocol from the running configuration. To restore the BGP4 configuration, you must
reload the software to load the configuration from the startup configuration. Moreover, when you
save the configuration to the startup configuration file after disabling the protocol, all the
configuration information for the disabled protocol is removed from the startup configuration file.
