VSR-NAT licensing

Appropriate licensing is required to enable the VSR-NAT functionality in the system. However, no further licensing enforcement is performed based on resource utilization, such as the consumed bandwidth or the number of NAT bindings.

The following NAT-related functionality is enabled through licensing:

LSN (LSN44, DS-Lite, and NAT64)
L2-Aware NAT
UPnP
geo-redundancy

You can use the CLI or MIB on VSR-NAT to get more information about the number of LSN bindings and LSN bandwidth.

Table: NAT licenses required to unlock NAT functionality describes the licenses required to unlock the VSR-NAT functionality.
