MPLS IPVPN “pipe mode” tunneling

["Ruben Tripiana Martin" <rtrim () gmx com>]

Hi all

 First of all I'm new to this list, so although I've checked the Mailing list FAQs, I apologize if my post is not 
appropriate.

 I decided to post these questions here as I think is one of the biggest networks engineering communities, and 
therefore with the biggest gained experience... and the questions are basically about that... experience. To get to the 
point, my questions are:

 Does anyone have any input regarding if a majority of global carriers offers “pipe mode” tunneling as regular feature 
in their MPLS IP-VPN services? According to your experience do you feel is fairly common?

 Thanks a lot in advance
