this problem. In CIDR, the address is allocated according to the network topology, and a contiguous set of network addresses can be assigned to a company and the entire set of addresses as a network address (for example, using the Hyper-network technology), with only one routing table entry on the external routing table. This solves the problem of address scarcity, and solves the problem of

At this point we can use the RIP protocol to configure

Route reduction is completed through the sub-commands under "router ospf", and this command is only valid on the VBR of the autonomous domain:Summary-address ip-address mask For example, router B injects an external route into the OSPF domain, and the injected subnet range is 126.1.96-127.

Basic knowledge of Cisco Routing Router The simplest network can be imagined as a single-line bus. Each computer can send packets to the bus to communicate with each other. However, as the number of computers in the network increases, this is not feasible and will cause many problems: 1. bandwidth resources are exhausted.2. Each computer wastes a lot of time processing unrelated broadcast data.3. The netwo
