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

[venkatesan mahalingam <[e-mail]>]

Hi,
Can we establish a LSP/PW between MPLS-TP operators with different
identifiers (ICC and Global_ID)?

for example,

Operator1
-------------------Operator2--------------------Operator3---------------------------Operator-4
(ICC)                             (ICC)
(Global_ID)                           (Global_ID)

Can single LSP/PW be traversed between Operator1 and Operator-4?
If the answer is NO, do we need to maintain two LSPs/PWs, one between
Operator1 and Operator2 and
another one between Operator3 and Operator4 and LSP/PW stitching with these
two LSPs/PWs for communication across operators?


Thanks,
Venkat.
