MED
在NE80E上通过路由策略来修改某条BGP路由的MED值的时候,在route-policy里可通过如下的哪条命令修改对应BGP路由的MED值()
A:apply med B:apply cost C:apply cost-type D:apply local-preference
对于BGP的MED(Multi-Exit Discriminators)属性,下列描述中正确的是()。
A:MED属性就是一个路由的外部度量Metric B:MED属性是在自治系统之间传递的 C:自治系统是使用MED属性来进行路由出自治系统的路由选择 D:当一个运行BGP自治系统得到目的地址相同、下一跳不同的多条路由时,在其它条件相同的情况下,MED较大的路由作为该自治系统的外部路由
以下有关MED属性的说法正确的是()。
A:MED属性是过渡属性 B:路由在传播过程中,其MED属性可以被改变 C:MED属性用来帮助其外部的邻居路由器选择一个较好的入口路径 D:MED属性用来帮助其外部的邻居路由器选择一个较好的出口路径
请问LOCAL-PREF与MED的区别。()
A:MED是可选过渡属性,LOCAL-PREF是公认非过渡属性 B:MED通常通过外部链路宣告给对等体,区分本地AS到同一邻居AS之间的多入口链路 C:LOCAL_PREF必须包含在UPDATE消息中,并传递到其它BGP邻居 D:LOCAL_PREF只能发布给IBGP邻居,数值越高越优先
关于BGP协议的localpref和MED属性,正确的说法是:()
A:localpref属性只在路由输入的时候生效 B:localpref属性在路由输入和输出的时候都能生效 C:MED属性只在路由输出的时候生效 D:MED属性在路由输入和输出的时候都能生效
