MPLS and VPN Architectures, CCIP™ Edition

Chapter 6.  MPLS Migration and Configuration Case Study

This chapter includes the following topics:

• Migration of the Backbone to a Frame-mode MPLS Solution

• Pre-migration Infrastructure Checks

• Addressing the Internal BGP Structure

• Migration of Internal Links to MPLS

• Removal of Unnecessary BGP Peering Sessions

• Migration of an ATM-based Backbone to Frame-mode MPLS

The previous chapters discussed the theory and configuration of the MPLS architecture within a Frame-mode and Cell-mode implementation. Now that this theory is clear, we should consider a case study that provides a migration example for both a router and an ATM-based backbone so that we can put the theory into practice.

Although this chapter provides a suggested basic migration path, this does ...
