What strategy can be employed to prevent routing loops aside from Split Horizon?

Route poisoning is a common strategy used to prevent routing loops in network environments. It works by marking a route as inaccessible or invalid by setting its metric to an extremely high value, effectively telling all routers that this route should not be used. When a route becomes unreachable, the routing protocol updates the affected routes with this poison value, allowing other routers to remove the faulty route from their tables. This action helps ensure that routers do not attempt to send packets through a route that has failed, which could otherwise lead to continual looping of packets within the network.

This method is part of various distance vector protocols, where the information about the route is propagated through the network to inform all routers about the new state of a previously available route. This prompt update prevents the reintroduction of improperly discarded routes and serves to stabilize the routing information across the network.

While options like Multi-Protocol Framework, Path Vectoring, and Static IP Routing do have their benefits in specific contexts, they do not address routing loops in the same manner as route poisoning does. Multi-Protocol Framework involves supporting multiple network protocols but does not inherently provide a mechanism to handle routing loops. Path Vectoring is typically used in path-vector protocols, like BGP, which manage routing decisions differently. Static IP
