waste. DHCP can be said to be an enhanced version of BOOTP. It is divided into two parts: one is the server, and the other is the client. All IP network settings are centrally managed by the DHCP server and are responsible for handling DHCP requirements of the client. The client uses IP environment data allocated from the server.

I believe you have a preliminary understanding of the use of the DHCP server. Therefore, we need to study this part in depth. This time, let's talk about BOOTP/DHCP Relay Agents. Next let's take a look at the specific introduction. If you need to create multiple DHCP servers, but the DHCP server and the client are loca

For vrouters, the status in the network is incomparable. So how should I configure DHCP for a vrodhcp? There are two VLANs in the network. To simplify the description, assume that each VLAN uses a 24-bit network address. The IP address of VLAN1 is 192.168.1.254, And the IP address of VLAN2 is 192.168.2.254. Implement the ios dhcp Server function on a Cisco device to automatically obtain IP addresses from ho

dhcp server responds to the dhcp-nak packet, it indicates that the lease of the IP address still exists, and dhcp relay will not aging the table items corresponding to the IP address; If the dhcp server does not respond to the handshake packet of the

DHCP server configuration under CentOS6.5 DHCP DHCP (Dynamic Host Configuration Protocol) is a LAN network Protocol that uses UDP for two purposes: to automatically assign IP addresses to internal network or network service providers, the user or internal network administrator is described in RFC 2131 as a means of central management of all computers.

Cisco DHCP configuration has always been our focus. We have also sorted out some materials in this regard. The following is the specific content. A company uses Cisco 3620 as the ios dhcp Server. the IP address of the fastethernet0 port connected to the Intranet is 192.168.1.4, And the L2 Switch uses two Cisco 2950, A layer-3 Switch uses a Cisco 3550. There are two VLANs in the network. To simplify the desc

After we have a detailed understanding of DHCP, we also know that it also has some service settings in the applications of a variety of routers and switches. Here we will focus on the configuration of dhcp relay. This time, we will explain the content of the dhcp server corresponding to the vlan interface configuration. ◆ Dh
