he most limiting lack in support that Packet Tracer has with BGP is the inability to create iBGP (Internal Border Gateway Protocol) peers. This means the user cannot create neighbors between routers within the same autonomous systems. Although even with this limitation there is sufficient support to allow the CCNA, and CCNP student to gain a basic understanding of this complex routing protocol and to learn how to use the following supported command within Packet tracer.

In the Internet, each packet traversing the network contains the address of the packet’s destination in its header. As with postal addresses, this address has a hierarchical structure. When a packet arrives at a router in the network, the router examines a portion of the packet’s destination address and forwards the packet to an adjacent router. More specifically, each router has a forwarding table that maps destination addresses (or portions of the destination addresses) to outbound links. When a packet arrives at a router, the router examines the address and searches its table using this destination address to find the appropriate outbound link had muter then directs the packet to this outbound link.

We just learned that a router uses a packet’s destination address to index a forwarding table and determine the appropriate outbound link. But this statement begs yet another question: how do forwarding tables get set? Are they configured by hand in each and every router, or does the Internet use a more automated procedure? But to whet your appetite here, we’ll note now that the Internet has a number of special routing protocols that are used to automatically set the forwarding tables. A routing protocol may, for example, determine the shortest path from each router to each destination and use the shortest path results to configure the forwarding tables in the routers.
