dellemc.enterprise_sonic.sonic_bgp_neighbors module – Manage a BGP neighbor and its parameters

Note

This module is part of the dellemc.enterprise_sonic collection (version 2.0.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

To install it, use: ansible-galaxy collection install dellemc.enterprise\_sonic.

To use it in a playbook, specify: dellemc.enterprise_sonic.sonic_bgp_neighbors.

New in dellemc.enterprise_sonic 1.0.0

Synopsis

• This module provides configuration management of global BGP_NEIGHBORS parameters on devices running Enterprise SONiC.

• bgp_as and vrf_name must be created on the device in advance.

Note

This module has a corresponding action plugin.
