LNS question asr 1002
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/
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
