Configuration of single-arm routing and DHCP for Cisco devicesIn this experiment, we will configure single-arm routing and DHCP to enable the PC to automatically obtain IP addresses and achieve network-wide interconnection. Tutorial steps: 1. configure the IP address and gateway of the PC. add different VLANs to the vswitch and divide different network segments f

After the new switch is bought, all need to be simple configuration to meet the unit network operation, after the configuration of the device will need to put it where it should be placed, but in the future we need to view or modify this device, we need to use remote login to configure it. Let's talk about the specific configuration of remote login.First, you need to use a dedicated configuration line (console line) to connect the deviceSecond, configure the line of another section of the connec

The default route to 10.0.0.0/8 is defined in OSPF, when OSPF link failure is ena

Cisco IOS is a dedicated kernel that provides routing, switching, network interconnection, and remote communication capabilities. Most Cisco routers are running iOS, and more and more Cisco Catalyst switches are running it, including Catalyst2960 and Catalyst3560 series switches. Some important aspects of the

Subnet Mask hardware basic Ethernet protocol Network Management A router is a bridge of a computer network and a core device connecting to an IP network. It can connect different networks, select data transmission routes, and block unauthorized access. Router configuration is not easy for beginners. Take the Cisco router as an example to introduce the general knowledge and configuration of the router for your reference When configuring the ro

, the measure (metric) is used to determine which route to join the routing table.Some common metrics are: hop count, bandwidth, latency, cost, load, reliability, etc. Hop count refers to the number of routers that are passed to the destination. Bandwidth refers to the capacity of the link, and the high-speed link overhead (measure) is small.The smaller the metric value, the higher the routing priority, so

copy of data is sent. The host or router can use IGMP to tell other routers that they are interested and then join multicast groups.

links, with millions of users. OSPF allows neighboring routers to establish adjacent relationships and transmit LSA information through DR and BDR. The region in OSPF is used to restrict the LSA and summarize the route information. Each router is connected to the region zero (main region.Network basics lecture 13: routing information protocol (RIP) Network basics
