Most of this stuff is on cisco or RFC1795 or RFC2166.
RFC1795 is DLSW v1. It has many issues that cisco addressed in DLSW+,
wich is a cisco propietary extension to DLSW v1.
Most if not all issues where afterwards addressed by DLSW v2 (RFC 2166)
but not exactly the same way. Also DLSW+ still has some advantages.
Nowadays, DLSW+ is "compatible" with DLSW v2 because it can talk to
a DLSW v2 router and agree to do DLSW v2, but AFAIK, there is no way
to force 2 cisco routers not to use DLSW+.
DLSW v2 uses port 2067 for 2 way comm (v1 uses 2065 one way, 2067
the other way) DLSW+ uses 2065 2 way.
That's almost all that I know :-)
