Refer to the exhibit. A network administrator is troubleshooting a BGP adjacency issue between routers R2 and R5. R2 uses loopback0 interface 2.2.2.2 and R5 uses loopback0 interface 5.5.5.5 in the neighbor ip_address remote-as as_number statement in their respective configurations. However, an adjacency does not form. Which two conclusions can be drawn from the troubleshooting process performed on R5? (Choose two.)

Refer to the exhibit. A network administrator is troubleshooting a BGP adjacency issue between routers R2 and R5. R2 uses loopback0 interface 2.2.2.2 and R5 uses loopback0 interface 5.5.5.5 in the neighbor ip_address remote-as as_number statement in their respective configurations. However, an adjacency does not form. Which two conclusions can be drawn from the troubleshooting process performed on R5? (Choose two.)

• R2 does not have a route to R5.
• R5 uses the default route to reach R2.
• There is no Layer 3 connectivity between R2 and R5.
• The interface with the IP address 10.1.45.5 on R5 is down.
• The AS number in the neighbor ip_address remote-as as_number statement is incorrectly configured on R2.

Explanation: Two BGP routers do not have to be directly connected or in the same subnet to form a BGP neighbor relationship; however, Layer 3 connectivity is required. For a router to have Layer 3 connectivity to the neighbor, it needs to have a route in the routing table that points to the neighbor router. In this case, there is no route in the routing table on R5 to reach R2. R5 can reach R2 via the default route configured on R5, BGP does not consider it a valid route for forming an adjacency.
