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.

The video walks you through configuration of IPv4-Compatible point-to-multipoint tunnel on Cisco router to transport IPv6 traffic over IPv4 network among multiple IPv6 sites. We will look at characteristics and requirements to implement IPv4-Compatible tunnel, and highlight its pros and cons. IPv4-Compatible tunnel does not rely on IP scheme to be in certain format like 6to4 or 6RD tunnels, but instead it requires the next-hop IP. This allows us to run routing protocol like BGP to automate route advertisement which you will see in this lab. Packet analysis on Wireshark will be performed to help us gain better understanding of the encapsulation and packet structure.

The video walks you through configuration of 6RD point-to-multipoint tunnel on Cisco router to transport IPv6 traffic over IPv4 network among multiple IPv6 sites. We will look at characteristics and requirements to implement 6RD tunnel, and highlight its pros and cons. 6RD tunnel is based on the same methodology as 6to4 tunnel but with greater flexibility in IP scheme. Packet analysis on Wireshark will be performed to help us gain better understanding of the encapsulation and packet structure.
