题目如下:
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.)
题目中的拓扑图请见最下面附件!
Select 2 response(s).
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

题目的意思是BGP的属性的都是使用的默认值,3个网络的流量分别是45%,20%,20%,要想使网络流量负载更加均衡,需要做什么配置。
因此我觉得应该是要把10.10.1.32/28和10.10.1.48/28的流量放在一起,那么才更均衡啊,因此我选答案是BD,但标准答案给的BC!!!
有哪位能帮忙解释下? |
