Explanation
When the discard option is configured as the next hop for a static route, it silently drops any packets that match the route without sending any notification to the sender. Discard Behavior: If a route uses the discard next hop, the router drops the packet without generating any ICMP message or error back to the sender. This is useful for creating null routes to prevent routing loops or blackhole traffic intentionally. Reject vs. Discard: The reject next hop, in contrast, drops the packet but sends an ICMP Destination Unreachable message back to the source.
