Small Remote Site LANs

Small/remote sites usually connect back to the corporate network via a small router (Cisco 2500). The local-area network service is provided by a small hub or LAN switch (Catalyst 1900). The router filters broadcasts to the WAN circuit and forwards packets that require services from the corporate network. A server may be placed at the small/remote site to provide DHCP and other local applications such as NT backup domain controller and DNS; if not, the router will need to be configured to forward DHCP broadcasts and other types of services. Figure 4-14 shows a typical architecture of a small or remote LAN. Building Cisco Remote Access Networks from Cisco Press is an excellent resource for more information on remote access.

LAN Media

The CCDA objectives covered in this section are as follows:

15 Recognize scalability constraints and issues for standard LAN technologies.

16 Recommend Cisco products and LAN technologies that will meet a customer's requirements for performance, capacity, and scalability in small-to medium-sized networks.

This section identifies some of the constraints that should be considered when provisioning various LAN media types. For additional reference material on this subject, refer to Appendix D, "LAN Media Reference."
