Poison reverse is a technique used in computer networking to prevent routing loops in distance-vector routing protocols. It involves advertising a route back to the neighbor it was learned from with an infinite metric to indicate that the route is unreachable. This helps to avoid packets being sent in circles during routing updates.
routing table
Metrics used by routing protocols are used to determine the best path for routing data packets. Different routing protocols use various metrics such as hop count, bandwidth, delay, load, and cost to make routing decisions. The choice of metric can impact the efficiency and effectiveness of the routing protocol in selecting optimal paths.

RIP (Routing Information Protocol) uses hop count as the metric. It measures the distance to a destination network based on the number of routers (hops) that a packet has to traverse to reach the destination.
