Scenario

In this Skills Assessment (SA) you will create a small network. You must connect the network devices and configure those devices to support various WAN protocols. This will require that you reload the routers before starting your configuration of the next WAN protocol. The assessment has you save your basic device configurations to flash prior to implementing a WAN protocol to allow you to restore these basic configurations after each reload.

The first WAN protocol you will configure is Point-to-Point Protocol (PPP) with CHAP authentication. You will also configure Network Address Translation (NAT), and network monitoring protocols during this phase of the assessment. After your instructor has signed off on this phase, you will reload the routers and configure Frame Relay. After the Frame Relay part is complete, and has been signed off by your instructor, you will reload the routers and configure a GRE VPN tunnel. Network configurations and connectivity will be verified throughout the assessment by using common CLI commands.

Note: To find out how the router is configured, look at the interfaces to identify the type of router and how many interfaces the router has. There is no way to effectively list all the combinations of configurations for each router class. This table includes identifiers for the possible combinations of Ethernet and Serial interfaces in the device. The table does not include any other type of interface, even though a specific router may contain one. An example of this might be an ISDN BRI interface. The string in parenthesis is the legal abbreviation that can be used in Cisco IOS commands to represent the interface.
