vlan and subnet

Full solution D-LINK Switch configuration in the enterprise network VLAN subnet usage, on the D-LINK Switch configuration problems, from the following aspects: from the enterprise network plan four VLAN subnet classification and structure, DES-3326SR Switch configuration process is introduced. The example below gives a

for virtual networks. In particular, it not only supports traditional port-based VLAN division, but also supports VLAN division based on IP addresses, subnet numbers, and protocol types, this brings great convenience to campus network management. Therefore, the new layer-3 Exchange router is used as the main device in the LAN of the campus and building. In addit

using ASIC hardware to achieve routing and switching at line speed, the latter represents the fast ip of 3com, and the virtual fast Security Network of cabletron. The method used is to route the network at the first layer, then, the second layer switches the end-to-end network stream data group. This is the policy of "one route, then switch. The powerful functions of the layer-3 Exchange router are as follows: 1) routes are calculated based on the L3 protocol. The supported routing protocols i

virtual IP, however, the benefit of VLAN implementation is that it can be linked to an existing three-layer switch or directly to the trunk of a standard IEEE 802.1q-enabled device. Mechanism platform, strategy opera. Now that the VLAN implementation Mechanism has been clear to the chest, then its shortcomings are estimated you also see, how to overcome it? Pvlan said the real is a

flow rules.(6) Finally, the Neutron L2 Agent will run an RPC loop task to handle port additions, deletions, and modifications when it is started. The administrator can specify the execution interval for the RPC looping task through the configuration item polling_interval, which defaults to 2 seconds.2.3 Create a virtual network and subnet 2.3.1 Create command[Email protected]:~$ neutron net-create net1 (or Admin user running neutron net-create net1--

Aggregation (VLAN Aggregation) technology, it allows hosts in different VLANs connected to the same vswitch and in the same IP segment to use the same default gateway for layer-3 communication. We know that in a common VLAN, even if all VLANs are in the same IP segment, a VLAN interface IP address must be configured for each

departments into different VLANs and map VLANs to different IP subnets. Therefore, the IP subnet policy is applicable to scenarios with low security requirements, network Design with high demands for mobility and simple management. The following command is usually used to set an IP subnet policy VLAN: Vlan 1 ip addres

ports to be a VLAN, and to configure IP addresses for that VLAN, then the computer in that VLAN is the gateway and the other VLANs cannot be on the same subnet as the VLAN.(4) VLAN partitioning based on IP multicast (built on the

[Translation] IP subnet division Original article title: IP subnetting made easy Address: http://articles.techrepublic.com.com/5100-10878_11-6089187.html IP network engineers need to have a solid understanding of how IP subnet division works. however, this topic is often ignored by instructors and the students are very confused and nervous about it. george ou developed a simple, graphical method to explain

Super-vlan : Achieve two-layer isolation, three-layer interoperability; all the Sub-vlan all three-tier communication needs to pass Super-vlan this gateway to implement; in a large network, saving IP Resources. VLAN communication can be achieved by simply configuring the Super-

First, the generation of Super VLAN backgroundIsolate-user-vlan successfully solved the problem of reducing the number of VLANs, and also realized the sharing of three-layer gateways to some extent. But it also has a problem with MAC address duplication that consumes MAC address table entries, and the technology itself belongs to a two layer VLAN technology.In a
