配置路由器LOOPBACK1地址，AR1使用1.1.1.1/32，AR2使用2.2.2.2/32，AR3使用3.3.3.3/32，AR4使用4.4.4.4/32。配置路由器之间的互联接口地址，AR1和AR3之间使用13.1.1.0/30，AR2和AR3之间使用23.1.1.0/30，AR3和AR4之间使用34.1.1.0/30。AR1的GE0/0/1使用10.1.1.1/24网段，AR1的GE0/0/2使用20.1.1.1/24网段，AR2的GE0/0/1使用30.1.1.1/24网段，PC1配置10.1.1.2/24，PC2配置20.1.1.2/24，PC3配置30.1.1.2/24
在AR1上GE0/0/1配置接口traffic-policy，禁止PC2访问PC1.
AS200自治域使用ISIS路由协议联通各路由器LOOPBACK地址，使用LOOPBACK地址建立IBGP连接。所有设备使用IS-IS进程号100，仅工作在Leve-2，区域号为86.0931，开销类型为wide。各设备的system id使用环回口1进行映射，如AR1的IP是1.1.1.1，其system id为0010.0100.1001。
AR3和AR4配置静态路由，使用LOOPBACK地址建立EBGP链接。
AR3上需要学习到10.1.1.0/24，20.1.1.0/24，30.1.1.0/24的路由。
在AR4的bgp邻居关系上配置路由策略，实现PC3无法访问AR4的LOOPBACK地址，PC1和PC2可以PING通AR4的LOOPBACK地址。
