1、RIPv2手动汇总RIPV2支持手动汇总拓扑如下： 配置如下：R1：interfaceEthernet0/0ipaddress 192.168.1.1 255.255.255.0routerripversion2network192.168.1.0noauto-summary---------------------R2：interfaceEthernet0/0ipaddress192.168.1.2 255.255.255.0interfaceEthernet0/1 ipaddress192.168.2

4、这样也同时减轻了路由器的负担。-----------------------------------------------------------------------------------------------------------------------------------------------------还有一种情况拓扑：R1的配置interfaceLoopback0 ipaddress192.168.96.1255.255.255.0interfaceLoopback1 ipadd
