  • Cisco enterprise customers have in the past relied heavily upon traditional WAN/MAN services for their connectivity requirements. Layer 2 circuits based on TDM, Frame Relay, ATM, and SONET have formed the mainstay of most low-speed WAN services. More recently, high-speed MAN solutions have been delivered directly over Layer 1 optical circuits, SONET, or through the implementation of point-to-point or point-to-multipoint Ethernet services delivered over one of these two technologies.

  • Implementing IP Addressing Services. Objectives: Configure DHCP in an enterprise branch network, Configure NAT on a Cisco router, Configure new generation RIP (RIPng) to use IPv6. Every device that connects to a network needs an IP address. Network administrators assign static IP addresses to routers, servers, and other network devices whose locations (physical and logical) are not likely to change. Administrators enter static IP addresses manually when they configure devices to join the network. Static addresses also enable administrators to manage those devices remotely....
