Introduction
In this practice skills assessment, you will configure the Small Business network with NTP, SNMP, EIGRP, PPP CHAP, Frame Relay, dynamic NAT, static NAT, PAT and a GRE tunnel.
Some values that are required to complete the configurations may not have been given to you. In that case, create the values that you need to complete the requirements.
For the sake of time, many repetitive, but important, configuration tasks have been omitted from this assessment. Many of these tasks, especially those related to security, are essential elements of a network configuration. The intent of this activity is not to diminish the importance of full device configurations.
You will practice and be assessed on the following skills:
- Configuration of NTP
- Configuration of SNMP and Syslog
- Configuration of interface addressing and basic settings
- Configuration of HDLC
- Configuration of Frame Relay
- Configuration of PPP
- Configuration of CHAP
- Configuration of a GRE tunnel
- Configuration of static and dynamic routing
- Configuration of dynamic NAT
- Configuration of static NAT
- Configuration of PAT
You are required to configure the devices as follows:
Office-1:
- Configure HDLC.
- Configure EIGRP.
- Configure passive interfaces.
R2:
- Configure PPP and CHAP authentication on the appropriate interface.
- Configure EIGRP.
- Configure static NAT for outside access to an internal server.
- Configure dynamic NAT.
- Configure PAT.
R3:
- Enable time stamps for use with NTP and SNMP logging.
- Configure the router to use NTP services.
- Configure logging to the IT Monitor Server.
- Configure PPP and CHAP authentication on the appropriate interface.
- Configure Frame Relay.
- Configure a GRE tunnel.
- Configure EIGRP.
- Configure passive interfaces.
Office-2-Branch:
- Configure Frame Relay.
- Configure a GRE tunnel.
- Configure EIGRP.
- Configure passive Interfaces.
Tables
In some cases, specific interface addresses have been provided to you. You must use them in your configurations. In other cases, when a network is specified instead of a specific address, you can use any address in the network.
You do not configure LAN addresses in this activity. The addresses of the LAN interfaces are provided in this table for reference purposes only.

Instructions
All configurations must be performed through a direct terminal connection to the device console from an available host.
Step 1: Configure NTP, SNMP, and Syslog settings on R3.
- Configure NTP.
- Configure R3 to use IT Monitor Server as its NTP server.
- Use a key value of 15.
- Configure SNMP.
- Use an SNMP community string of CiscoPTSA.
- Allow the SNMP management station only read only rights.
- Configure Syslog.
- Configure R3 to use time stamps when logging. The timestamps should include milliseconds.
- Configure Syslog to send log entries to the IT Monitor Server.
- Set the message trapping for Syslog to the debugging level.
Step 2: Configure Frame Relay between R3 and Office-2-Branch.
Configure Frame Relay on the interfaces connecting R3 and Office-2-Branchusing the information from the Addressing Table. You must use the exact addresses specified in the addressing table for the configuration.
Step 3: Configure a GRE Tunnel between R3 and Office-2-Branch.
- Configure a GRE tunnel using Tunnel interface 0 on R3 to Office-2-Branch using information from the addressing table.
- Configure a GRE tunnel using Tunnel interface 0 on Office-2-Branchto R3 using information from the addressing table.
- You must use the exact addresses specified in the addressing table for this configuration.
Step 4: Configure DCE interfaces.
Configure the DCE interfaces of R2 with a clock rate of 128000.
Step 5: Configure PPP and CHAP between R2 and R3.
- Configure interface addressing according to information provided in the Addressing Table. You can use any address in the network specified in the Addressing Table for this configuration.
- Authenticate the PPP connection with CHAP on both ends of the link.
- Use the password of PTSAchap.
Step 6: Configure HDLC on Office-1 and R2.
It has been decided to remove an earlier PPP configuration from the link between Office-1 and R2.
- Configure this link with HDLC.
- Configure interface addressing according to information provided in the Addressing Table. You can use any address in the network specified in the Addressing Table.
Step 7: Configure NAT on R2.
All hosts should use translated addresses to access destinations outside of the Small Business network.
- Configure static NAT.
- Configure static NAT for the IP address of the Partner Server.
- Use the last host address in the interface S0/1/0 subnet.
- Configure dynamic NAT.
- Configure dynamic NAT for all host IP addresses on the LAN network connected to Office-1.
- Use DYNAMIC as the name for the pool.
- Use the third through tenth IP addresses that are available on the R2 S0/1/0 subnet.
- Configure ACL 1 to allow all host IP addresses in Office-1 LAN network to use this group of addresses.
- Your ACL should have one statement.
- Configure PAT.
- Configure PAT to enable the hosts attached to the R3 and Office-2-Branch LANs to access the Internet.
- Use the interface keyword in the NAT statement.
- Use ACL 2 to allow all host addresses on both LAN networks to use the overload address.
- Your ACL should have two statements.
- Configure all interfaces on R2 as appropriate.
Step 8: Configure static and dynamic routing.
- Configure dynamic routing.
- Configure EIGRP for all networks connected to Office-1, R2,R3, and Office-2-Branch.
- Use ASN 1.
- Use the precise inverse masks for all networks.
- Disable automatic summarization on all routers.
- Disable EIGRP updates from being sent on the appropriate interfaces. You must do this for each individual interface. Donot use the default keyword with the command.
- Configure a redistribute a default route.
- Create a directly attached default route to the Internet on R2.
- Configure EIGRP to redistribute the default route to the other routers.
