Today, almost all mainstream operating systems and embedded operating systems provide support for the IPv6 protocol stack. in Windows XP, you can use the IPv6 install command to start the IPv6 protocol stack, in the default Linux environment, you can use modprobe IPv6 to load the I
In the process of learning DHCP, We need to master a lot of content, such as the configuration of these routers and switches. This time, we will systematically explain the configuration of the router DHCP function. Hope to help you.

Three configuration methods for IPv6 in Linux: 1. automatically obtain the IPV6 address, modify the/etc/sysconfig/network file, add the following configuration text NETWORKING_IPV6 = yes, and then, run the Command service network restart and run the command ifconfig-a to view IPV6
Understand:There are several types of IPV6 unicast addresses, including global unicast addresses, link-local addresses, and site-local addresses.1. The global unicast address is equivalent to the IPV4 public address and is provided to the network service provider.This type of address allows the aggregation of route prefixes, thereby limiting the number of global routing table entries.2. Link-local address for Neighbor Discovery protocol and statele
In everyone's mind, DHCP gets the address is a lease, the lease is, the client will regain the IP address, when the IP address obtained is likely to change compared to the original, which is very detrimental to network management. With static IP, the address will not change, but to modify up to each machine to row a little trouble, error prone.
In fact, DHCP generally have address reserved address function
Article Title: Quickly configure DHCP server configurations in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
In the past, we have learned the basic content of the DHCP service, and we have also learned how to configure DHCP

There are two methods for configuring IPv6 in the windows system family: IPv6 and netsh. We can use them to query and configure IPv6 interfaces, addresses, caches, and routes. Take the IPv6 command in windows xp as an example: ◆ IPv6 install

The well-known multicast addresses defined in routing protocols are as follows:
Multicast address of local RIP route for all links: FF02: 9
Multicast address of the local OSPF route for all links: FF02: 5
Multicast address of the ospf dr route on all links: FF02: 6

DHCP server learning DHCP configuration want to learn the contents of the DHCP server, for its basic concepts and configuration of the content we have to understand. So let's start with a quick look at DHCP.
1. Introduction to DHCP Service
DHCP is Dynamic host Configuration Protocol, which is a way to assign IP addresses to hosts in a physical network, distinguishing them from BOOTP, and assigning a lifetime use disadvantage.
The concept of a DHCP-proposed lease makes it possible to dynamically determine the IP address r
In everyone's impression, the IP address obtained by DHCP has a lease. Once the lease arrives, the client will obtain the IP address again, at this time, the obtained IP address may change compared with the original one, which is unfavorable to network management. If a static IP address is used, the address will not change if the IP address is not moved. However, it is troublesome to change the IP address of each server, which is prone to errors.

Let's do a simple experiment on Ros today, in a typical dozens of-person small company or a few people's home, if you come to how Ros do the most basic internet operation.Knowledge Points:
Ros as a DHCP Server for the intranet.
Ros as the client of PPPoE (the average person rarely uses ADSL access)
Ros makes a pat so that intranet users can surf the Internet.
The topology diagram is as follows:650) this.width=650; "src=" Http://s
In some settings, we usually see the configuration of the DHCP relay function. In a TCP/IP-based LAN, communication between computers depends on the IP address of the host. Therefore, each server and workstation in the network must have a unique IP address. The IP address allocation method is very important for effective network management.
IP Address Allocation Method
Generally, IP addresses are allocated
The address pool in the DHCP server is organized in a "Tree" structure. The root is the address of the natural CIDR block. Each branch is the subnet address of the CIDR block, and the leaf node is the client address manually bound. This tree structure achieves configuration inheritance, that is, the subnet (son node) configuration inherits the

In the previous article, we explained what DHCP Snooping is. So we have a general understanding of this through the content of the article. Next, we will take a look at the specific operations and steps of DHCP Snooping configuration. The DHCP Snooping function and the DHCP
