By attempting to pass all of the ANVL tests which
sent L2TP messages that were technically in violation
of the spec, we had problems interoperating some other
implementations which weren't as strict in what they sent
or perhaps had a slightly different interpretation of what
was compliant.

After a few minor changes made at the bake off and by 
adopting the "be strict in what you send and liberal in what
you receive" philosophy, we were able to interoperate
quite well.

Hi,
since I am going to use ANVL L2TP test suite to test a LAC, could you be so
kind
to better explain me what you mean with "interoperability problems with all
but
the most militantly conformant L2TP implementations"?
Thanks a lot, Federica Anfosso

I have used the test suite as well. It was useful, but it had
quite a few bugs. ANVL/Midnight/Hammer has reportedly fixed quite
a number of them.

One note of caution: If you attempt to "pass" all of the negative
defensive tests, you are likely to have interoperability problems
with all but the most militantly conformant L2TP implementations.

Hi Srikrishnan,
We have been using Anvil testing software for the past few months, and it
has helped us a lot in detecting bugs in the PPP, L2TP and PPTP modules. The
test cases are quite thorough, and they bring out the small mistakes which
one might generally overlook.

Regards

Hi Guys,

  Has anyone used Anvil's L2TP - PPP Stack for testing L2TP/PPP stacks?

  If anyone has used, can u please send how useful is that product?

Regards
