protocol between as is called the External Gateway Protocol External Gateway Protocol (also called Inter-Domain routing protocol): there are two types of inter-domain routing protocols: externalGateway Protocol (EGP) and Border Gateway Protocol (BGP)2) Dynamic routing according to the algorithm can be divided into: Distance vector routing protocol, link state routing protocolDistance Vector Routing protocol: Select Route RIP,IGRP based on the number of routes that are routed from the source net

Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the

Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP
