What happens when RouterA receives a packet that does not match any routes in its static routing table?

When RouterA receives a packet that does not match any routes in its static routing table, it discards the packet. This occurs because the router relies on its routing table to determine the appropriate next hop for forwarding incoming packets. If there are no specific routes defined for the packet’s destination and no default route available to handle unmatched packets, the router has no valid path to direct the packet. Consequently, it cannot deliver it to its intended destination and must drop it to maintain the integrity of the network.

In many networking configurations, routers are typically set to forward packets that align with established routes. If nothing matches, they are designed to protect network resources by eliminating undefined traffic that could cause confusion or inefficiencies. In this case, having no valid route means the packet cannot be forwarded appropriately, leading to its disposal.
