|
|
notes:
|
|
- Tested against NXOSv 7.3.(0)D1(1) on VIRL
|
|
- VRF needs to be added globally with M(nxos_vrf) before
|
|
adding a VRF to an interface.
|
|
- Remove a VRF from an interface will still remove
|
|
all L3 attributes just as it does from CLI.
|
|
- VRF is not read from an interface until IP address is
|
|
configured on that interface.

|

|
