Network topology exhibit
Based on the exhibit, what is the correct BGP confederation required on Domain 4?
A.
router bgp 65001
bgp confederation indentifier 65101
bgp confederation peers 65002 65003
neighbor 10.3.3.5 remote-as 65001
neighbor 10.1.1.2 remote-as 65002
neighbor 10.2.2.3 remote-as 65003
neighbor 192.168.1.1 remote-as 65102
B.
router bgp 65001
bgp confederation indentifier 65001
bgp confederation peers 65002 65003
neighbor 10.3.3.5 remote-as 65001
neighbor 10.1.1.2 remote-as 65002
neighbor 10.2.2.3 remote-as 65003
neighbor 192.168.1.1 remote-as 65102
C.
router bgp 65101
bgp confederation peers 65001 65002 65003
neighbor 10.3.3.5 remote-as 65001
neighbor 10.1.1.2 remote-as 65002
neighbor 10.2.2.3 remote-as 65003
neighbor 192.168.1.1 remote-as 65102
D.
router bgp 65001
bgp confederation peers 65002 65003
neighbor 10.3.3.5 remote-as 65001
neighbor 10.1.1.2 remote-as 65002
neighbor 10.2.2.3 remote-as 65003
neighbor 192.168.1.1 remote-as 65102
Explanation:
router bgp 65001 % Confed AS number, not the real BGP AS number as seen by real EBGP neighbor
bgpconfederation identifier 65101 % Actual AS number as seen by real EBGP peer. The confederation identifier refers to external AS number neighbor 10.3.3.5 remote-as 65001
For B,C and D, they all have the incorrect bgp confederation identifier
