Instructions

All configurations must be performed through a direct terminal connection to the device console lines from an available host.
Part I: EIGRP Router Configuration
Step 1: Plan the Addressing.
Determine the IP addresses that you will use for the required interfaces on the devices and LAN hosts. Follow the configuration details provided in the Addressing Table.
Step 2: Configure East.
Configure East with initial settings:
  • Configure the router host name: East. This value must be entered exactly as it appears here.
  • Prevent the router from attempting to resolve command line entries to IP addresses.
  • Protect device configurations from unauthorized access with an encrypted secret password.
  • Secure the router console and remote access lines.
  • Prevent system status messages from interrupting console output.
  • Configure a message-of-the-day banner.
  • Encrypt all clear text passwords.

No ip domain look up
Enable secret class
Line console 0
Password cisco
Logging sinchronus
Login
Line vty 0 4
Password cisco
login
Banner motd “Authorized Access Only”
Service password-encryption

Step 3: Configure the Router Interfaces.
Use the information in the addressing table to configure the interfaces of all routers for full connectivity with the following:
  • Configure IP addressing.
  • Descriptions for all physical interfaces.
  • Configure DCE settings where required. Use a rate of 128000.
  • The Ethernet subinterfaces on West will be configured later in this assessment.
Step 4: Configure inter-VLAN routing on West.
Configure router West to route between VLANs using information in the Addressing Table and VLAN Switch Port Assignment Table. The VLANs will be configured on the switches later in this assessment.
  • Do not route the VLAN 99 network.
Step 5: Configure EIGRP Routing and a default route.
a. On all routers:
  • Configure EIGRP for IPv4 to route between the internal networks. Use ASN 100.
  • Use the precise wild card masks for all network statements.
  • You are not required to route the SW-Admin VLAN network over EIGRP.
  • Prevent routing updates from being sent on the LAN networks.  Do not use the default keyword version of the command to do so.
  • Prevent EIGRP for IPv4 from performing automatic route summarization on all routers.
b. On the Central router:
  • Configure a default route to the Internet. Use the exit interface argument.
  • Configure EIGRP for IPv4 to distribute the default route to the other routers.
Step 6: Customize EIGRP for IPv4.
Customize EIGRP for IPv4 by performing the following configuration tasks:
  • Set the bandwidth of the link between East and Central to 128 kb/s.
  • Create a summary route for the LANs connected to Bldg3. It should include all networks from 10.10.0.0 to 10.10.15.0.
  • Do not include the SW-Admin VLAN network in the summary route.
  • Configure EIGRP for IPv4 with the route summary so that it will be sent to the other routers. Be sure to configure the summary on all of the appropriate interfaces.
Step 7: Configure Access Control Lists.
You will configure two access control lists in this step. You should use the any and host keywords in the ACL statements where appropriate. The ACL specifications are as follows:
a.  Restrict access to the vty lines on Central with an ACL:
  • Create a named standard ACL using the name TELNET-BLOCK. Be sure that you enter this name exactly as it appears in this instruction.
  • Allow only Test PC to access the vty lines of Central.
  • No other Internet hosts (including hosts not visible in the topology) should be able to access the vty lines of Central.
  • Your solution should consist of one ACL statement.
b.  Block ping requests from the Internet with an ACL:
  • Use access list number 101.
  • Allow only Test PC to ping addresses within the Medical Company network. Only echo messages should be permitted.
  • Prevent all other Internet hosts (not only the Internet hosts visible in the topology) from pinging addresses inside the Medical Company network. Block echo messages only.
  • All other traffic should be allowed.
  • Your ACL should consist of three statements.
  • Your ACL should be placed in the most efficient location as possible to conserve network bandwidth and device processing resources.
c. Control access to the management interfaces (SVI) of the three switches attached to West as follows:
  • Create a standard ACL.
  • Use the number 1 for the list.
  • Permit only addresses from the NetAdmin VLAN network to access any address on the SW-Admin VLAN network.
  • Hosts on the  NetAdmin VLAN network should be able to reach all other destinations.
  • Your list should consist of one statement.

Part II: Switching and DHCP Configuration
Step 1: Create and name VLANs.
On all three switches that are attached to West, create and name the VLANs shown in the VLAN Table.
  • The VLAN names that you configure must match the values in the table exactly.
  • Each switch should be configured with all of the VLANs shown in the table.
Step 2:  Assign switch ports to VLANs.
Using the VLAN table, assign the switch ports to the VLANs you created in Step 1, as follows:
  • All switch ports that you assign to VLANs should be configured to static access mode.
  • All switch ports that you assign to VLANs should be activated.
Step 3:  Configure the SVIs.
Refer to the Addressing Table. Create and address the SVIs on all three of the switches that are attached to West. Configure the switches so that they can communicate with hosts on other networks. Full connectivity will be established after routing between VLANs has been configured later in this assessment.

Step 4:  Configure Trunking and EtherChannel.
a. Use the information in the Port-Channel Groups table to configure EtherChannel as follows:
  • Use LACP.
  • The switch ports on both sides of Channels 1 and 2 should initiate negotiations for channel establishment.
  • The switch ports on the Bldg2 side of the Channel 3 should initiate negotiations with the switch ports on Bldg3.
  • The switch ports on the Bldg3 side of Channel 3 should not initiate negotiations with the switch ports on the other side of the channel.
  • All channels should be ready to forward data after they have been configured.
b. Configure all port-channel interfaces as trunks.
c. Configure static trunking on the switch port on Bldg2 that is connected to West.
Step 5:  Configure Rapid PVST+.
Configure Rapid PVST+ settings as follows:
a. Activate Rapid PVST+ and set root priorities.
  • All three switches should be configured to run Rapid PVST+.
  • Bldg1 should be configured as root primary for VLAN 2 and VLAN 4 using the default primary priority values.
  • Bldg1 should be configured as root secondary for VLAN 8 and VLAN 15 using the default secondary priority values.
  • Bldg3 should be configured as root primary for VLAN 8 and VLAN 15 using the default primary priority values.
  • Bldg3 should be configured as root secondary for VLAN 2 and VLAN 4 using the default secondary priority values.
b. Activate PortFast and BPDU Guard on the active Bldg3 switch access ports.
  • Configure PortFast on all access ports that are connected to hosts.
  • Activate BPDU Guard on all access ports that are connected to hosts.
Step 6:  Configure switch security.
You are required to complete the following only on some of the devices in the network for this assessment. In reality, security should be configured on all devices in the network.
a. Secure unused switch ports. Following security best practices, do the following on Bldg1 only:
  • Shutdown all unused switch ports.
  • Configure all unused switch ports as static access ports.
  • Ensure that all unused switch ports have been assigned to VLAN 99.
b. Configure port security on all active access ports on Bldg1.
  • Each switch port should accept only two MAC addresses before a security action occurs.
  • The learned MAC addresses should be recorded in the running configuration.
  • If a security violation occurs, the switch ports should provide notification that a violation has occurred but not place the interface in an err-disabled state.
c. On Bldg2, configure the virtual terminal lines to accept only SSH connections.
  • Use a domain name of ccnaPTSA.com.
  • Use a modulus value of 1024.
  • Configure SSH version 2.
  • Configure the vty lines to only accept SSH connections.
  • Configure user-based authentication for the SSH connections with a user name of netadmin and a secret password of SSH_secret9. The user name and password must match the values provided here exactly in case, punctuation, and spelling.
Step 7: Configure West as a DHCP server for the hosts attached to the Bldg1 and Bldg2 switches.
Configure three DHCP pools as follows:
  • Create a DHCP pool for hosts on VLAN 2 using the pool name vlan2pool.
  • Create a DHCP pool for hosts on VLAN 4 using the pool name vlan4pool.
  • Create a DHCP pool for hosts on VLAN 8 using the pool name vlan8pool.
  • All VLAN pool names must match the provided values exactly.
  • Exclude the first five addresses from each pool.
  • Configure a DNS server address of 192.168.200.225.
  • All hosts should be able to communication with hosts on other networks.
Step 8: Configure host addressing.
All hosts should be able to ping each other and the two external servers after they have been addressed.
  • Hosts on VLANs 2, 4, and 8 should be configured to receive addresses dynamically over DHCP.
  • Hosts on VLAN 15 should be addressed statically as indicated in the addressing table. Once configured, the hosts should be able to ping hosts on other networks.
  • Hosts on the LANs attached to East should be statically assigned addressing that enables them to communicate with hosts on other networks.
