[c-nsp] LNS question asr 1002

[Nitzan Tzelniker]

Do you talk about ASR-1002x or ASR1002 ?
Take a look on this page (Cisco didn't update it with new models for a long
time )
http://www.cisco.com/c/en/us/td/docs/routers/asr1000/configuration/guide/chassis/asrswcfg/scaling.html

The 1002 is limited to 12K
We didnt test the 1002-x but on a 1004 with ESP-20 and RP2 we cross the 32K
L2TP sessions without a problem (48K and even 64K for short time )  but it
is not recommended to cross the limits
