Binding overlay access list

You must first create an overlay access list that you want to bind to an overlay transit.

Use the overlay-transit command to create an overlay transit.
```
device(config)# overlay-transit abc_ext
```

Use the overlay access-group command to bind an overlay access list to an overlay transit.

device(config-overlay-transit-vxlan1)# overlay access-group abc_ext in

Only one overlay access list can be bound to an overlay transit.

(Optional) Use the no overlay overlay access-group command to unbind an overlay access list.

device(config-overlay-transit-vxlan1)# no overlay access-group vlx_al in
