You can use feature add-on licenses to add memory to the Cisco CSR 1000v/Cisco ISRv. Memory is allocated to both the IOSd component and the data plane component. The amount of the memory allocation is dependent on the licenses installed.
You can install multiple 4 GB add-on licenses. You can add 4 GB of additional memory by installing the broadband feature license and then install further 4 GB add-on licenses.
The following table lists how the memory is allocated depending on the amount of VM Memory and the feature licenses installed.
