Summary
In this chapter, you learned the concepts and practical configuration, verification, and troubleshooting steps of the tunneling and transport of Layer 2 WAN protocols over an IPv4 infrastructure using L2TPv3. You worked through multiple case studies, including static and dynamic configuration of L2TPv3 sessions and transport of multiple WAN protocols such as HDLC, PPP, Frame Relay, and different flavors of ATM.This chapter compared and contrasted L2TPv3 to transport diverse WAN protocols, in addition to L2TPv3 and AToM as pseudowire technology for WAN protocol transport. You learned L2TPv3 control plane theory and practice through multiple messaging exchange examples, data plane characteristics including the use of an Layer 2-Specific Sublayer, packet decodes, and MTU considerations. |
