Re: [mpls-tp] MPLS-TP tunnel and PW establishment over multiple different operators

[venkatesan mahalingam <[e-mail]>]

Hi,

I guess transport people will be able to provide more pointers and
suggestions against such deployment possibilities for MPLS_TP.
Is this not a valid scenario that needs to be discussed?

Thanks,
Venkat.
