We have Juniper MX80 and MX5's and a show system licenses shows:
Licenses Licenses Licenses Expiry
Feature name used installed needed
scale-subscriber 0 1000 0 permanent
scale-l2tp 0 1000 0 permanent
scale-mobile-ip 0 1000 0 permanent
I've Google'd but I have no idea what these license actually do?
If anyone knows what they are for it would be much appreciated.
