module: nxos_bgp
version_added: "2.2"
short_description: Manages BGP configuration.
description:
- Manages BGP configurations on NX-OS switches.
author:
- Jason Edelman (@jedelman8)
- Gabriele Gerbino (@GGabriele)
extends_documentation_fragment: nxos
notes:
- C(state=absent) removes the whole BGP ASN configuration when
C(vrf=default) or the whole VRF instance within the BGP process when
using a different VRF.
- Default when supported restores params default value.
- Configuring global parmas is only permitted if C(vrf=default).
