BFD is a common fast detection technology. It implements the fast switchover function only when collaborating with other fast switchover technologies.
BFD is a common fast detection technology. It implements the fast switchover function only when collaborating with other fast switchover technologies.
Bidirectional Forwarding Detection (BFD) can independently provide fast failure detection times for various network topologies, media types, encapsulations, and routing protocols. Therefore, it does not require collaboration with other fast switchover technologies to implement the fast switchover function.
Which is the default network mask length of 219.25.23.56?
The IP address 219.25.23.56 falls within the range of Class C addresses, which are defined by the first three octets ranging from 192.0.0.0 to 223.255.255.255. The default network mask length for a Class C address is 24 bits.
On a non-broadcast network, OSPF has two operating modes: NBMA and P2MP.
On a non-broadcast network, OSPF indeed has two operating modes: Non-Broadcast Multi-Access (NBMA) and Point-to-Multipoint (P2MP). These modes are specifically used in non-broadcast environments to handle the communication between OSPF routers.
How many Class C networks does the summarized route 192.168.134.0/22 cover?
The summarized route 192.168.134.0/22 covers 4 Class C networks. The /22 subnet mask means we are using 22 bits for the network portion, which leaves 10 bits for the host portion across the third and fourth octets. Converting this to the affected range of Class C networks, we start at 192.168.134.0 and the range extends to 192.168.135.255. Therefore, the networks covered are 192.168.134.0, 192.168.135.0, 192.168.136.0, and 192.168.137.0, making it 4 Class C networks.
Which statements about OSPF packets are true? (Choose three.)
Hello packets can be sent once OSPF is enabled on an interface to establish communication with other OSPF routers, making statement A true. LS Request packets are indeed sent only after an adjacency is established to obtain more recent LSA information, which makes statement B true. LS Update packets contain detailed LSA information but are sent after an adjacency is established for proper synchronization, aligning with statement D. While LS Update packets include LSA details, their main role in synchronization occurs after adjacency is formed, and thus, C isn’t accurate in the context of the question.
