[c-nsp] MPLS-TE on ME3600

[Pshem Kowalczyk]

Hi,

We use ME3600x with MPLS TE. I can't comment on the first point (we
don't have multiple areas), but on the second one - path protection is
protection end-to-end, whilst FRR uses a local repair mechanism, so
these two are quite different in the way they work. FRR on that device
works fine and provides protection for both originated and transit
LSPs. On the third point - yes, that's a limitation. I'm not sure if
it's a hardware or a software one.

kind regards
Pshem
