MPLS

The video demonstrates configuration of RIPv2 as PE-CE routing protocol in Cisco MPLS VPN. RIPv2 will be used per VRF to replace the static routes that we configured in the previous video. We will also look at how RIP metric is carried across MPLS in MPBGP advertisement and how it can be manipulated. 

The video introduces you to fundamental of MPLS VPN and this includes the concepts of VRF, Route Distinguisher (RD), and Route Target (RT). We will be build a basic MPLS VPN network from scratch using ISIS as our IGP. Two MPLS VPN customers will be used to demonstrate the routing separation this technology has to offer. Multi-Protocol BGP (MPBGP) will be discussed and configured for VPNv4 route exchange. Static route will be used for a PE-CE routing as other routing protocols will be looked at in the following labs. Wireshark packet capture will be performed at the end of the lab to compare MPLS VPN packet to a regular MPLS packet.

The video shows a way of reducing convergence time of LDP on Cisco router with targeted LDP. You will see how targeted LDP is able to maintain LDP session to a neighbor router even after a link to that router has gone down so they do not need to go through session establishment and label exchange after link recovery, and, hence, improve convergence time. While targeted LDP requires specific configuration between two LDP peers, session protection allows you to create targeted LDP to all neighbors with essentially a single command and this will also be covered in this video.

The video demonstrates a process of enabling MD5 authentication for LDP session on Cisco router. There are usually two ways to accomplish this and those are configuring it at the global level as a default authentication for all LDP neighbors, or at the per-neighbor level. You also have a option to tie an authentication to multiple key-chains for even more flexibility. All of these will be covered in this video.

The video focuses on LDP label advertisement on Cisco router. You will learn how to define a number range for MPLS label and control which labels are to be sent to and received from a MPLS neighbor using label filter. By default, a default route does not have a label assigned and we will show you how this behavior can be overwritten. The video finishes with a discussion of LDP transport address and configuration on how to change it from the default of LDP router-id.

The video introduces you to MPLS ping and traceroute, which are important tools that will help you in troubleshooting a MPLS network. We will explain the differences from traditional ping and traceroute and demonstrate how you can use them to track down label discontinuity which may cause MPLS packet drop. We will the discuss the significant of MRU and its effect to packet fragmentation. Wireshark packet capture will be performed throughout this video to show you the MPLs packet structure.

The video lays a foundation of MPLS by looking at configuration of Label Distribution Protocol (LDP) on Cisco router. We will learn how MPLS routers use LDP to discover their neighbors, create series of LDP sessions to form a Label Switching Path (LSP), and finally exchange MPLS labels. LDP binding table will be examined in attempt to understand how a packet is label-switched from an ingress to an egress router. Wireshark capture will be performed as we will spend time analysing LDP messages and packets.
