ASR Carrier grade NAT licence

Hi,

I am checking out the licences for NAT444 and NAT64. I see these two licences for the ISM on ASR9K.

A9K-CGN-LIC-5M     CGN License Unit for 5 Million translations

A9K-DSLT-LIC-5M  DS-Lite License Unit for 5 Million translations

CGN means Carrier Grade NAT and DSLT means Dual Stack Lite.

Now I do not know what licences to choose for our requirements. I received an error when I chossed both licences.

Can anyone help me out?

Hi,

I accidentaly found this question in the forum, and I don't know if you received answers to it.

I suppose it should probably a better fit for the XR section than LAN, Switching and Routing.

We don't currently support NAT64 in XR4.2.1. Currently, we support NAT44 and DS-Lite on ISM card.

The Stateful NAT64 is expected to be in 4.3.0 (in Late December this year).

You need one license for each technology and the number of licenses is based on the number of concurrent sessions you plan to handle per card: the minimum is 5 millions sessions. If you need 20M sessions, you'll need 4 of them.

Hope it clarifies,

Cheers,

Nicolas.

Hello,

thank you for the answer. I already found out that (thanks to a Cisco guy) NAT64 will be supported in a future release.
