课程：Building Cisco Remote Access Network (BCRAN) v2.0
适用认证：CCIE/CCNP
考试号：642-821 BCRAN
先决条件：
The BCRAN course focuses on introducing techniques and technology for enabling secure 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 IP Protocols and IP Utility applications
* 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
Note: These topics are covered in the CCNA courses
CCNA Basics and Interconnecting Cisco Network Devices (ICND)v2.0
课程内容：
In the Building Cisco Remote Access Networks course, students learn how to build,configure and troubleshoot a remote access network to interconnect central sites to branch offices and small offices/home offices. Students also learn how to control access using basic authentication and authorization configurations,how to maximize bandwidth utilization over the remote links, and how to set up virtual private networks (VPNs) using IPSec.
Course Objectives
Upon completion of this course, the student will be able to parform the following overall tasks:
* Given a network design, interconnect the network devices as specified by the design and installation plan.
* Given a network design,build a functional configuration to support the specified network operational requirements
* Given a completed network implementation, verify the functionality of the network to ensure that it functions as specified.
* Given available tools, verify connectivity to non-Cisco devices.
* Using the command line interface, accurately determine network device operational status and network performance.
* Using IOS commands,manage device configuration files to reduce device downtime and according to best practices.
* Using the command line interface, configure access lists to meet specified operational requirements
* Using the appropriate show commands, display network operational paramenters so that the student can detect anomalies
* Using the appropriate debug commands, monitor network operational parameters so that the student can detect anomalies
