MPLS - any Security Holes known?

[DocValde <DocValde () gmx de>]

Hi everybody,

MPLS  (Multi  Protocol  Label  Switching) seems to be a quite exotic technology since it is
only  interesting for providers or big companies, so my search for any known weaknesses is
still   a   little   bit   successless.   I  only found a test report at mier.com, who are
quite "Cisco  friendly"  and some information by Michael Behringer from Cisco Systems, which
are "just" the official stuff...

I  would appreciate any further information on MPLS security, since Nortel Networks stated
it as "much buggy", but do not explain that "much" (Anyone from Nortel reading?).
Personal mail responses are welcome, and of course kept personal.

Best regards and TIA,

Malte von dem Hagen
