华为ISIS实验记录 实验要求 如拓扑图所示，客户网络所有路由器路由协议要求启用IS-IS，使全网路由可达。全部IS-IS进程号统一为100， 其中AR5在Area49.0001区域为DIS。 AR2与AR1之间要求采用P2P网络类型， AR1引入直连链路192.168.X.X，要求AR5访问Area49.0002走最优路径。 根据上述描述，进行正确配置，使网络路由达到客户需求。  拓扑图配置记录1. 全网route配置ip address；AR5配置isis进程号100 ：isis 100，network-entity 49.0002.0000.0000.0005.00 （区域ID.系统ID.两位小数是网络服务访问点（selector）），路由角色为L1：is-level level-1，AR3和AR4 区域ID一样49.0002， 路由角色设置为L1-2（相当于ospf中的abr角色），AR1、AR2设置区域ID为49.0001、骨干区、route角色为L2、使全网互通。2. AR5设置为DIS：接口下配置 isis dis-priority 120 level-13. AR2与AR1之间要求采用P2P网络类型，接口下配置 isis circuit-type p2p 4. AR1 引入直连路由192.168.x.x import-route direct5.要求AR5访问Area49.0001走最优路径：ar3致Area49.0001为以太链路比ar4过去的串口链路要优，ar3 isis设置路由渗透 import-route isis level-2 into level-1（将l1 l2的路由引入 让ar5访问过去走ar3，否则是两边都走即负载均衡）全route配置AR1<ar1>disp cur [V200R003C00] #
