short_description: Manages L3 attributes for IPv4 and IPv6 interfaces

author: Jason Edelman (@jedelman8), Gabriele Gerbino (@GGabriele)
|
||||
notes:
|
||||
- Interface must already be a L3 port when using this module
|
||||
- Logical interfaces (po, loop, svi) must be created first
|
||||
- I(mask) must be inserted in decimal format (i.e. 24) for
|
||||
both IPv6 and IPv4.
|
||||
- A single interface can have multiple IPv6 configured.
|
||||
|
||||

|
||||
