Router RIP is attempting to establish BGP neighbor relationships with
routers RT1 and RT3. On the basis of the information that is presented in the exhibit, which
two statements are true? (Choose two)

A.
RTR has a BGP password set but neighbor 10.0.0.1 does not

B.
RTR has a BGP password set but neighbor 10.0.0.5 does not

C.
RTR has a BGP password set but neighbor 10.0.0.1 has an incorrect password set

D.
RTR has a BGP password set but neighbor 10.0.0.5 has an incorrect password s

E.
Neighbor 10.0.0.1 has a BGP password set but RTR does not

F.
Neighbor 10.0.0.5 has a BGP password set but RTR does not

Explanation:
You can configure MD5 authentication between two BGP peers, MD5 authentication must be
configured with the same password on both BGP peers; otherwise, the connection between
them will not be made. If a router has a password configured for a peer, but the other peer
does not, a message “No MD5 digest from…” will appear on the console while the routers
attempt to establish a Multicast Source Discovery Protocol (MSDP) session between them.
Therefore A is correct because RT1 (with an ip address of 10.0.0.1) is not configured with a
password.
Similarly, if the two routers have different passwords configured, a message “Invalid MD5
digest from…” will appear on the screen.
