Common configuration tasks

About this task

This task provides a brief overview of the tasks that must be performed to configure BGP and provides the CLI commands. To enable BGP, one AS must be configured and at least one group must be configured which includes neighbor (system or IP address) and peering information (AS number).

All BGP instances must be explicitly created on each router. After the instances are created, BGP is administratively enabled.

Configuration planning is essential to organize ASs and the SRs within the ASs, and determine the internal and external BGP peering.

To configure a basic autonomous system, perform the following steps.

Procedure

  1. Prepare a plan detailing the autonomous systems, the router belonging to each group, group names, and peering connections.
  2. Associate each router with an autonomous system number.
  3. Configure each router with a router ID.
  4. Associate each router with a peer group name.
  5. Specify the local IP address that is used by the group or neighbor when communicating with BGP peers.
  6. Specify neighbors.
  7. Specify the autonomous system number associated with each neighbor.
