Refer to the exhibit. Currently the two eBGP links between AS100 and AS200 have an average inbound
load of 65% and 20% respectively. After further investigation, traffic to 10.10.1.16/28 accounts for 45%, and
traffic to 10.10.1.32/28 and to 10.10.1.48/28 each account for 20% of the inbound load. The BGP attributes
are currently set at their default values in both autonomous systems.
If you want to influence how AS200 sends traffic to AS100, which eBGP configurations would you configure
in AS100 to influence AS200 to use the eBGP links more evenly? (Choose two.)
A. neighbor 192.168.30.2 route-map as_50 out
B. neighbor 192.168.20.2 route-map as_50 out
C. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.16 0.0.0.240
D. route-map as_50 permit 10
match ip address 50
set metric 150
access-list 50 permit 10.10.1.32 0.0.0.240
Answer: BC
答案B没有问题,但是我觉得CD里面应该是选D,设置一个高的med给 10.10.1.32/28,而不是10.10.1.16. 否则的话, 45%跑去下面,岂不是还是不均衡,不知道答案是不是弄错了,求解释,谢谢。
