[c-nsp] L2TP problem with 7301

[Arie Vayner (avayner)]

Guys,

There is no stable MPF version, as this whole thing has been
discontinued, and is not being developed or supported any more.

people are seeing in the real world..

Tried that IOS on 7301 with PPPoE/PTA scenario. Worked like a charm for
about five hours, then crashed and was "downgraded" to 12.4...

Performance boost is really impressive, 4%+18% CPU load at 300mbit
traffic (~800 users online) compared with 40-50% CPU load on 12.4 with
the same numbers for traffic/users, but stability is the something we
need more than performance..

PS: if anyone knows really stable ios with MPF - let me know, too :)
