Hello,

I read that MPLS uses the IP control plan. What would it mean?

Thanks,
Michelot

That statement doesn't make sense without a lot more explaination behind it
because without a context, it could mean just about anything.

I read it as control plane.

Sadly I can't think how to explain right now. And I may
be wrong, again.

Hi Thrill5 and bod43,

Let's consider an IP/MPLS network. If MPLS uses IP routing protocols,
we can't say that MPLS is connectionless, like it is for IP.

(1) What's the main difference between OSPF and OSPF-TE ?

(2) MPLS can setup its own path setup once it has the IP routing map.
Do you know why?

Best regards,
Michelot

It's probably for a PE which has an LSR function together with an IP
router function. For a pure LSR which doesn't terminates the IP path,
the LSP path set up doesn't need to run firstly an IP routing
protocol.

It seems there are ambiguous statements about that.

Best regards,
Michelot
