Tiernan,
You are indeed correct. Giles did indeed mention that we are running MPLS
on our Juniper M160 core network and I am rolling out MPLS VPNs on a wider
scale across Europe. This service is not currently available for customers
of Level 3 as the Juniper equipment is not currently capable of supporting
MPLS VPNs (Juniper have a release of software that should cover this
functionality early next 2001). There are work-arounds to allow end-to-end
MPLS VPNs but these will not be implemented for customers as they do not
scale.
We will be pursuing further work in this area early next year.
Regards,
James Cumming

I don't mean to intrude, as I'm a journalist who lurks, not a carrier
representative. But I thought I'd point out that at last week's "IP Over
WDM"
conference in Paris, Giles Heron, of Level 3 Communications, remarked that
the
company has MPLS running in its Juniper M160 routers and that the firm has
been
running MPLS VPNs in London for six months. Heron remarked the gating factor
at
this point is getting the firm to price such a service for commercial
deployment,
and, on the technical side, the service can not be run out to the edge of
the
network until there is compatibility between Juniper and Cisco's respective
label
distribution protocol (LDP) software. Once this happens, Giles expects the
company will try to run MPLS across the entire network between the Juniper
switches and Cisco 7500 routers.
I'm not really qualified to assess any of this information, but thought I'd
offer
it to the group since I came across it at the conference.
