DEFAULT GATEWAY: 192.168.123.254 ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ------------------------------------
============================================================================================================================================================================================================= ==================== Current routing: Destination Destination Network Segment Mask Subnet Mask Interface The exit IP Gateway next to the destination IP Gateway next hop router entry IP, the router defines the link to the next router via interface and Gateway, usually, Interface and Gateway are Metric hops of the same network segment, the quality of the routing record, in general, if there are multiple Routing records to the same destination, the router uses the route that the metric value is small.
The first default routing: Means, when a packet's destination network segment is not in your routing record, then your router should send the 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 2 default routing: The routing record means: When I receive a packet, 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 points to your machine. If you receive such a data, what should I send to where the route recorded line quality 1
Article 4 Routing Records of the Double Dinner Section: How to handle this situation when the router receives a packet to the line segment, the interface and Gateway of routing records are the same. When I received a packet's destination is 192.168.123.0, I will send it directly through 192.168.123.68 interface, because this port is directly connected to 192.168.123.0 network segment, the route record Line quality 1
Article 5 Routing Records of Directive Network Section When I receive a packet of a packet is 192.168.123.0, I will send it directly through 192.168.123.88 interface, because this port is directly connected to 192.168. 123.0 This network segment, the line quality of the route record 1
Article 6 Local Host Routing: How do I handle how to handle the destination network segment I receive a packet when the router receives a packet, I will receive the data package because of this data Send it to my own package, the line quality of the route record
Article 7 Local Host Routing: How do I handle the destination network segment that the router receives a packet when I receive a packet is 192.168.123.88, I will receive the data package because of this data. Send it to my own package, the line quality of the route record
Article 8 Local Broadcasting Routing: How to handle how the router receives the local broadcast segment to the line segment When I receive a broadcast packet, I will take the data from 192.168.123.68 interface The broadcast of the broadcast is sent, and the line quality of the route record is 1
Article 9 Local Broadcasting Routing: How to handle the destination network segment that the router receives the local broadcast segment is 192.168.123.255, I will use the data from 192.168.123.88 interface The broadcast of the broadcast is sent, and the line quality of the route record is 1
Article 10 Multicast Routing: How to handle when the router receives a multicast packet When I receive a multicast packet, I will send the data from the 192.168.123.68 interface to a multicast situation, the route Recorded line quality 1
Article 11 Multicast Routing: How do I handle when the router receives a multicast packet When I receive a multicast packet, I will send the data from the 192.168.123.88 interface to a multicast situation. Routing record line quality 1
