1、每台设备BGP route id修改为自己的router id
2、AR4上有10.1.1.0/24,要求AR1访问AR4走上面的链路。使用协议首选值
3、在AR1发给AR3的10.1.1.0/24网段的路由协议首选值改为100,其他传递的路由协议首选值不变
4、要求RR设备访问20网段的时候通过AR3走,如果没有通过AR3发出则通过修改开销值的方式实现选路,并且不影响AR3去往AR2的loopback接口路由
5、在AR1上通告192.168.1.0/24网段,让AR4从AR2学习到的路由本地优先级改为50,从AR3学到的路由本地优先级改为80
6、AR5发布了一条10.1.5.0/24的路由,AR6上发布了一条10.1.6.0/24的路由。但是AR4访问5.0的路由时走AR6访问。AR4访问6.0的时候从AR5来走。要求在AR4上通过MED来实现。
7、AR1访问5.0网段走AR2,访问6.0网段走AR3,使用AS-path
8、在AR3上将AR1发来的20.1.1.0网段的路由和2.0网段路由起源属性修改为?
