What is split horizon?
  • a)
    Information about a route should not be sent back in the direction from which the original update came.

    It splits the traffic when you have a large bus (horizon) physical network.
  • c)
    It holds the regular updates from broadcasting to a downed link.
  • d)
    It prevents regular update messages from reinstating a route that has gone down.

Split Horizon:

Split Horizon is a technique used in computer networking to prevent routing loops in distance-vector routing protocols. Here is an explanation of the concept in detail:

Information Restriction:
- In split horizon, information about a route should not be sent back in the direction from which the original update came. This means that a router will not advertise a route back to the same router from which it learned about that route.
- By not sending updates back to the source, split horizon prevents routers from mistakenly reinstating a route that has gone down, thus avoiding routing loops.

Preventing Routing Loops:
- One of the main reasons for implementing split horizon is to prevent routing loops, which can occur when routers continuously exchange incorrect routing information with each other.
- By restricting the flow of routing information back to the source, split horizon helps maintain a more stable and accurate routing table within a network.

Downed Link Handling:
- Split horizon also plays a role in handling downed links. It holds the regular updates from broadcasting to a link that is no longer functioning, preventing unnecessary traffic from being sent to that link.
- This helps in maintaining network efficiency and preventing unnecessary congestion on failed links.

In conclusion, split horizon is a valuable technique in network routing that helps in preventing routing loops and managing downed links effectively. By restricting the flow of routing information back to the source, it enhances the stability and efficiency of a network's routing infrastructure.
