DEFAULT GATEWAY: 192.168.123.254 ============================================== =============================== Current routing: Destination Destination Network Segment Mask Subnet Mask Interface Arrival Reach The destination The IPGATEWAY IPGATEWAY IPGATEWAY IP, the router is transferred to the next router through Interface and Gateway defines the link to the next router. Usually, Interface and Gateway are the metric hop of the same network segment, which recorded Quality, in general, if there are multiple routing records arriving at the same destination, the router will use the METRIC value small routing first default route: meaning, when a packet's destination network segment is not in yours In the routing record, then your router should send that packet to where! The gateway of the default route is the way the route recorded by Default Gateway on your connection is: When I receive a destination network segment of a packet is not in my routing record, I will pass the packet through 192.168. 123.88 This interface is sent to 192.168.123.254 this address, this address is an interface of the next router so that this packet can be delivered to the next router process, not related to me. The route recorded line quality 1 Article 2 default routing: The routing record means: When I receive a destination network segment of a packet is not in my routing record, I will pass the data package through 192.168.123.68. The interface is sent to 192.168.123.254 this address, this address is an interface of the next router so that this packet can be delivered to the next router process, not related to me. The line quality of the route record 1 Article 3 Local Loop: 127.0.0.0 All addresses in this network segment point to your machine. If you receive such a data, what should I send to where the route recorded line quality 1 Article 4 Route Record of the networked section: How to deal with the router to receive a packet sent to the line segment, this situation, the interface and Gateway of routing records are the same.
