Which of the following reasons will not cause the BFD session to go Down?
The detection mechanism of BFD is that two systems establish a BFD session and periodically send BFD control messages along the path between them. If one party does not receive the BFD control message within a specified time, it is considered that a fault has occurred on the path. Which...

In the network shown in the figure, adjacent routers use directly connected interfaces to establish EBGP neighbor relationships. The Router ID of each device is 10.0.0.X, and the AS number is 6500X, where X is the router number. R1 and R4 both have static routes to 192.168.1.0/24, which are imported into BGP. R1 adds the community attribute value (1:1) when sending routes to its neighbors. All routers in the network are enabled to pass community attributes. Which of the following can make the traffic path from R3 to 192.168.1.0/24 pass through R4?
