- Manages VRRP configuration on NX-OS switches.

author:

- Gabriele Gerbino (@GGabriele)
|
|
notes:
|
|
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
|
|
- VRRP feature needs to be enabled first on the system.
|
|
- SVIs must exist before using this module.
|
|
- Interface must be a L3 port before using this module.
|
|
- C(state=absent) removes the VRRP group if it exists on the device.
|
|
- VRRP cannot be configured on loopback interfaces.
