[j-nsp] Mirroring packets in an LSP

[Alex]

Hi Joe,
I never tried this myself but it might work:
1/ buy an Y-splitter cable(s) and connect attenuated end(s) to an unused 
router port(s).
2/ configure "pop-all-labels" on that port or ports

3/ And from there you could port-mirror the traffic to another port with 
analyser attached or next-hop-group.
