Enabling and disabling BGP4
BGP4 is disabled by default. To enable BGP4, you must perform the following steps.
1. Enable the BGP4 protocol.
2. Set the local AS number.
NOTE
BGP4 is not functional until you specify the local AS number.
3. Add each BGP4 neighbor (peer BGP4 device) 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.
Virtual ADX enable
Virtual ADX# configure terminal
Virtual ADX(config)# router bgp
BGP4: Please configure 'local-as' parameter in order to enable BGP4.
Virtual ADX(config-bgp-router)# local-as 10
Virtual ADX(config-bgp-router)# write memory
Syntax: router bgp
The router bgp command enables the BGP4 protocol.
