Question

What is the next step that a router takes while using a distance-vector protocol?

A) Broadcast its entire routing table
B) Send updates only to neighboring routers
C) Request information from a central server
D) Establish a direct point-to-point connection

Answer 1

Using a distance-vector protocol, a router sends updates of its entire routing table exclusively to neighboring routers. This approach helps maintain the efficiency and stability of the network. The correct option is B) Send updates only to neighboring routers

Step-by-step explanation:

When using a distance-vector protocol, a router takes the following step after learning respective distances and directions to reachable networks: B) Send updates only to neighboring routers.

In distance-vector routing protocols like RIP (Routing Information Protocol), each router sends out periodic updates of its entire routing table, but only to its immediate neighbors. This method helps prevent the issues of routing loops and count-to-infinity problems by limiting the scope of the updates.

The next step that a router takes while using a distance-vector protocol is B) Send updates only to neighboring routers. In a distance-vector protocol, routers exchange information with their directly connected neighbors to determine the best path to forward packets.

Rather than broadcasting its entire routing table, a router using a distance-vector protocol only sends updates to its neighboring routers, which then propagate the updates to their neighbors.

The correct option is B) Send updates only to neighboring routers
