[c-nsp] Issue with MPLS implementation using cisco ME-3750-24TE-M within our backbone

[thucydide tajouo]

I said : "Note that between PE and LSR, we use VLANs interface (because MPLS cannot be enable on physical interfaces)." because of what you can see on the image in attach according to this 

http://www.cisco.com/c/en/us/td/docs/switches/metro/catalyst3750m/software/release/12-2_55_se/configuration/guide/3750metro_scg/swmpls.html#wp1182634

until now, i realize that when  MPLS is disabled on MPLS cloud interfaces, i can ping from one customer from another but when i enable it again, ping cannot pass.

Bests regards

What do you mean here? You can only do MPLS on the rightmost two SFP 
interfaces on the ME3750.

Apart from that they have very little RAM and forwarding table, everything 
is fine :P They're very restricted, make sure you test them properly for 
your scaling needs.
