Routing & Switching

The video demonstrates more advanced BGP route advertisement features on Cisco routers. BGP uses only one best route by default so we will look at how we can configure a router to load balance between multiple equal-cost routes. We will test the router ability to limit the number of prefix being learnt from its peer and react accordingly. Finally, we will show how you can gain more control with conditional advertisement that is based on existence of another route.

The video shows you how to advertise routes into BGP on Cisco routers. We will look at different methods of advertising routes and the effect they have on route Origin attribute. We will discuss the default behavior of routes being learnt from eBGP and then advertised into iBGP, and the importance of 'next-hop-self' command. Default route advertisement will also be demonstrated at the end of the video.

The video gets you  started on BGP with basic neighbor configuration on Cisco router. We will be configuring both iBGP and eBGP, and this will serve as fundamental configuration for our future labs. In additional, we will look at two features; Fast-External-Fallover and Graceful restart. This lab is all about bringing up BGP neighbor sessions and there will be no route advertisement.

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.
