Question 2

Based on the R1 router BGP configuration shown, which three statements are correct? (Choose three)

hostname R1 ;
router bgp 50001
bgp confederation identifier 50101
bgp confederation peers 50002 50003
neighbor 10.1.1.1 remote-as 50001
neighbor 10.2.2.2 remote-as 50001
neighbor 10.3.3.3 remote-as 50001
neighbor 10.1.1.1 router reflector-client
neighbor 10.2.2.2 router reflector-client
neighbor 10.3.3.3 route-reflector-client
neighbor 10.4.4.4 remote-as 50002
neighbor 10.5.5.5 remote-as 50003
neighbor 192.168.100.1 remote-as 50102
neighbor 192.168.100.1 route-map setlp in
neighbor 192.168.100.1 route-map setmed out
no sync
!

A. R1 is in AS 50101 according to the 192.168.100.1 neighbor.
B. R1 is in AS 50101 according to the 10.1.1.1 neighbor.
C. The 192.168.100.1 neighbor must be directly connected to R1.
D. R1 is a route-reflector client.
E. The 10.4.4.4 neighbor is an EBGP neighbor.
F. BGP updates coming in from the 192.168.100.1 neighbor must be processed by the setlp route-map.

 

Answer: A C F
