wireshark

The video gets you started on Cisco MPLS Traffic Engineering (TE). We will look at the fundamental of MPLS TE including routing protocol, specifically ISIS, metric support, additional routing information the protocol needs to carry, and the role of Resource Reservation Protocol (RSVP) in bandwidth reservation, MPLS label distribution, and tunnel establishment. As a quick demonstration, we will configure a basic MPLS TE tunnel, perform Wireshark packet capture, and review RSVP packets.

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 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.

The video shows you configuration of a BGP peer across multiple L3 hop on Cisco router. You will understand the default TTL value of BGP packets and how to overcome this to support a BGP peer that not directly connected. We will look at two viable options; ebgp-multihop and TTL security, and make comparison. Wireshark packet capture and analysis will be performed throughout the video to give you insight behind the protocol and packet structure.  

The video walks you through configuration of Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) point-to-multipoint tunnel on Cisco router to transport IPv6 traffic over IPv4 network among multiple IPv6 sites. ISATAP tunnel work similarly to the IPv4-Compatible tunnel with the IPv4 tunnel destination embedded in the next-hop IP. Unlike other tunnelling technologies, ISATAP supports Router Advertisement over the tunnel allowing dual-stack hosts to connect directly to the default router. We will look at two ways of default router discovery: manual and DNS. Packet analysis on Wireshark will be performed to help us gain better understanding of the encapsulation and packet structure.
