题224 组网如图所示,RTA、RTB位于AS 1001,RTC、RTD、RTE位于AS 1002,AS1001向AS1002发布BGP路由11.11.11.0/24,RTC、RTD的BGP主要配置如下,如果RTE、TRC的互联链路中断,RTE访问11.11.11.0/24网段,优先经过哪条关于链路? [RTC] bgp 1002 Preference 20 170 200 Peer RTA as-number 1001 Peer RTD as-number 1002 Peer RTA router-policy setned import Route-policy setned permit node 10 Apply cost 100 [RTD] bgp 1002 Preference 20 170 200 Peer RTB as-number 1001 Peer RTC as-number 1002 Peer RTA router-policy setned import Route-policy setned permit node 10 Apply cost 200 A. 优先经过广域链路一,因为RTC的MED 100<RTD的MED 200 B. 优先经过广域链路一,因为RTC上的eBGP路由优先 C. 优先经过广域链路二,因为RTD的MED 200>RTC的MED 100 D. 优先经过广域链路二,因为RTD上eBGP路由优先 |
