short_description: Manages Cisco EVPN VXLAN Network Identifier (VNI).
description:
- Manages Cisco Ethernet Virtual Private Network (EVPN) VXLAN Network
Identifier (VNI) configurations of a Nexus device.
- Manages Cisco Ethernet Virtual Private Network (EVPN) VXLAN Network
Identifier (VNI) configurations of a Nexus device.
author: Gabriele Gerbino (@GGabriele)
notes:
- default, where supported, restores params default value.
- RD override is not permitted. You should set it to the default values
first and then reconfigure it.
- C(route_target_both), C(route_target_import) and
C(route_target_export valid) values are a list of extended communities,
(i.e. ['1.2.3.4:5', '33:55']) or the keywords 'auto' or 'default'.
- The C(route_target_both) property is discouraged due to the inconsistent
behavior of the property across Nexus platforms and image versions.
For this reason it is recommended to use explicit C(route_target_export)
and C(route_target_import) properties instead of C(route_target_both).
- RD valid values are a string in one of the route-distinguisher formats,
the keyword 'auto', or the keyword 'default'.
- default, where supported, restores params default value.
