BGP configuration task list
In a basic BGP network, you only need to perform the following configurations:
• Enable BGP.
• Configure BGP peers or peer groups. If you configure a BGP setting at both the peer group and the

To control BGP route distribution and path selection, you must perform additional configuration tasks.
To configure BGP, perform the following tasks (IPv4):
