All,
There has been some discussion lately about the use of MPLS
LSPs to
carry NETLMM signaling. Traffic engineering has been quoted
as a reason
to do this. I'm trying to understand the vision behind this
and what
kind of traffic engineering benefits people see this
offering.
I agree with Vijay's statement that TE would lead to per-MN
LSPs and
that isn't exactly scalable.
So, is it just the thought of exploiting the existence of
MPLS backbones
for transport of NETLMM signaling between the AR and MN? Or,
are there
more reasons behind this?
Thanks,
Vidya
