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.)
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
Correct answer should be B and D.
Prefer the path with the lowest multi-exit discriminator (MED). The default MED value is 0.
Set 10.10.1.32/28 with MED value 50 on eBGP link AE.
This traffic will prefer eBGP link BF to area 200 because other default values are equal.
