BCRAN (Building Cisco Remote Access Networks)

Prerequisites
The BCRAN course focuses on introducing techniques and technology for enabling WAN
solutions. To fully benefit from BCRAN, the student must be familiar with general networking terms and concepts and have experience completing the following tasks on Cisco routers:

• General Cisco router operation and configuration
• TCP/IP operation and configuration
• Routing Protocols (RIP, IGRP)
• Routed Protocols (IP, IPX)
• Standard and extended access lists
• PPP operation and PPP configuration over serial links
• Frame Relay operation and configuration on interfaces and subinterfaces
• Legacy DDR over ISDN-BRI operation and configuration

Course Objectives
Upon completion of this course, the student will be able to perform the following overall tasks:

• Identify the appropriate Cisco products for a given set of WAN technology requirements, including permanent or dialup access between a central site, branch offices, and telecommuters.
• When given a set of WAN topologies and specifications assemble and configure Cisco equipment to establish appropriate WAN connections.
• Enable protocols and technologies that allow traffic flow between multiple sites, while minimizing the amount of overhead traffic on each connection.
• Implement quality of service capabilities to ensure that mission critical applications
  receive the required bandwidth within a given WAN topology.
• Within a given WAN topology, implement applicable access control measures to allow desired access into the network.
• When given a WAN topology, ensure proper connectivity using Cisco product features to troubleshoot device protocols and technologies.

Course Content

• Troubleshooting Remote sites
• Connecting Single and Multiple Branch Offices
