RIPv2手动汇总.docx

RIPv2手动汇总RIPV2支持手动汇总拓扑如下：配置如下：R1：interface Ethernet0/0ip address 192.168.1.1 255.255.255.0router ripversion 2network 192.168.1.0no auto-summary-R2：interface Ethernet0/0ip address 192.168.1.2 255.255.255.0interface Ethernet0/1ip address 192.168.2.2 255.255.255.0router ripversion 2network 192.168.1.0network 192.168.2.0no auto-summary-R3：interface Loopback 0ip address 3.3.0.1 255.255.255.0interface Loopback 1ip address 3.3.1.1 255.255.255.0interface Loopback 2ip address 3.3.2.1 255.255.255.0interface Loopback 3ip address 3.3.3.1 255.255.255.0interface Ethernet0/0ip address 192.168.2.1 255.255.255.0ip summary-address rip 3.3.0.0 255.255.252.0router ripversion 2network 3.0.0.0network 192.168.2.0no auto-summary手动汇总应用在路由更新的出接口方向上在R1上查看路由表：汇总成为了/22的路由了，这样减小了路由条目，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interface Loopback0ip address 192.168.96.1 255.255.255.0interface Loopback1ip address 192.168.97.1 255.255.255.0interface Loopback2ip address 192.168.98.1 255.255.255.0interface Loopback3ip address 192.168.99.1 255.255.255.0router ripversion 2redistribute staticnetwork 192.168.1.0network 192.168.96.0network 192.168.97.0network 192.168.98.0network 192.168.99.0no auto-summaryexitip route 1 92.168.96.0 255.255.252.0 null 0用静态路由的方式进行重发布，在接口上做的话提示：表示汇总后的掩码要大于等于主类网络的掩码长度，所以写一条静态路由指向空
