Sometimes when we purchase a L2 service from a service provider, we need to have our L2 protocols tunneled.

ASR920 platform gives the operator three option to choose from:

• l2protocol tunnel
• l2protool peer
• l2protocol forward

Although I've been working with ASR920s for a while, I didn't have the time to lab this up and see what are the differences. Until now!
