Refer to the exhibit. An engineer is reaching network 172.16.10.0/24 via the R1-R2-R4 path. Which configuration forces the traffic to take a path of R1-R3-R4?
A. R1(config)#route-map RM_LOCAL_PREF permit 10
R1(config-route-map)#set local-preference 101
R1(config-route-map)#exit
R1(config)#router bgp 100
R1(config-router)#neighbor 13.13.13.3 route-map RM_LOCAL_PREF in
R1(config-router)#end
R1#clear ip bgp 13.13.13.3 soft in
B. R1(config)#route-map RM_AS_PATH_PREPEND
R1(config-route-map)#set as-path prepend 200 200
R1(config-route-map)#exit
R1(config)#router bgp 100
R1(config-router)#neighbor 12.12.12.2 route-map RM_AS_PATH_PREPEND in
R1(config-router)#end
R1#clear ip bgp 12.12.12.2 soft in
C. R1(config)#router bgp 100
R1(config-router)#neighbor 13.13.13.3 weight 1
R1(config-router)#end
D. R2(config)#route-map RM_MED permit 10
R2(config-route-map)#set metric 1
R2(config-route-map)#exit
R2(config)#router bgp 200
R2(config-router)#neighbor 12.12.12.1 route-map RM_MED out
R2(config-router)#end
R2#clear ip bgp 12.12.12.1 soft out
Correct Answer: B
