1 Jun 2009This article is intended for those new to Cisco Express Forwarding and its impact on the way Multilayer Switching is done in Cisco hardware. Of course, this article can also serve as a review for those familiar with Cisco Express Forwarding but are looking for a refresher. In this first article we are going to go over the components that make up this switching architecture followed by some fundamental examples to illustrate these components and concepts at work. Before we get started be sure to download the topology we are going to be using in the lab examples for clarity.

13 May 2009One of the most essential products for a business or individual that runs a private network is a cisco router to protect internet access. If you need to protect your internet or intranet network then a cisco router will do the job. Cisco are the market leader in router hardware.
(VTP) is a Cisco Layer 2 messaging protocol that manages the addition, deletion, and renaming of VLANs on a network-wide basis. Virtual Local AreaNetwork (VLAN) Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst Family products. VTP ensures that all switches in the VTP domain are aware of all VLANs. There are occasions, however, when VTP can create unnecessary traffic. All unknown unicasts and broadcasts in a VLAN are flooded over the entire VLAN. All switches in the network receive all broadcasts, even in situations where few users are connected in that VLAN. VTP pruning is a feature used to eliminate (or prune) this unnecessary traffic. By default, all Cisco Catalyst switches are configured to be VTP servers. This is suitable for small-scale networks where the size of the VLAN information is small and easily stored in all switches (in NVRAM). In a large network, a judgment call must be made at some point when the NVRAM storage needed is wasted, because it is duplicated on every switch. At this point, the network administrator should choose a few well-equipped switches and keep them as VTP servers. Everything else participating in VTP can be turned into a client. The number of VTP servers should be chosen so as to provide the degree of redundancy desired in the network.
