(Lesson 1: 2011-06-19 1. Introduce the external gateway EGP is divided into: EGP has a class, and the convergence speed is slow. BGP has no class. It is generally used in relatively large networks and within operators. BGP: The purpose is to make policy, the network used when a large network is connected to the operator. Start routing, use BGPAS: autonomous system, large area, multiple exits. A collection in the same administrative domain. (OSPF, the AS of eigrp is called a process) If the AS is compared to a router, then the relationship between the router and the router is called: EBGP. BGP within an AS is called IBGP. Host: Single-homed (also called single-homed), connected to an AS, with a single wire connection or multiple wire connections. Dual-homed, connected to more than two ASs, used for routing: all receive a default route, at least consume routing resources; import default routes and some detailed routes (if two default routes are introduced, one will appear Suboptimal routing) All routing tables on the Internet are received, if they are received, there will be more than 300,000 routes. That would be BGP, mainly using some policies based on attributes.)
