|

notes:
|
||||
- The feature vpc must be enabled before this module can be used
|
||||
- If not using management vrf, vrf must be globally on the device
|
||||
before using in the pkl config
|
||||
- Although source IP isn't required on the command line it is
|
||||
required when using this module. The PKL VRF must also be configured
|
||||
prior to using this module.
|
||||
- Both pkl_src and pkl_dest are needed when changing PKL VRF.
