Part 2: Configure Addressing and DHCP

You will configure DHCP and interface addressing on router Branch-101 to prepare for implementing the wireless LAN controller network.

Step 1: Configure and address a subinterface for the WLAN user network.

a. Configure subinterface 10 on the router interface that is connected to the switch S4-1.

b. The router should provide router-on-a-stick routing to VLAN 10.

c. Configure the subinterface with the address from the Addressing Table.
Brand-101 Router

Branch-101(config)#interface g0/0/0.10
Branch-101(config-subif)#description WLAN users
Branch-101(config-subif)#encapsulation dot1q 10
Branch-101(config-subif)#ip address 192.168.10.1 255.255.255.0

Step 2: Configure a DHCP pool for WLAN user network.

a. Exclude the router interface address and the management address of the WLC.

Branch-101(config)#ip dhcp excluded-address 192.168.10.1
Branch-101(config)#ip dhcp excluded-address 192.168.10.254

b. Configure a DHCP pool that will be used by hosts that are connecting to the WLAN.

1. Name the pool WLAN-hosts.
2. Configure the pool to use addresses in the 192.168.10.0/24 network.

Branch-101(dhcp-config)#default-router 192.168.10.1
Branch-101(dhcp-config)#dns-server 198.51.100.163

Step 3: Configure an interface as a DHCP client.

On Branch-101, configure the interface that is connected to ISP Router to receive its address over DHCP.

Branch-101(config)#interface g0/0/1
Branch-101(config-if)#ip address dhcp
Branch-101(config-if)#exit

Part 3: Configure Static Routes

In this part of the assessment you will configure static, default, floating static, and host routes in both IPv4 and IPv6. You will configure the Central and Branch-101 routers. Netacad PLC has decided that it wants to use static routing between all its networks. In addition, the company wants to use the Ethernet links between routers for most data traffic and reserve serial link between Central and Branch-101 for backup purposes in case one of the Ethernet links becomes unavailable. You will be configuring floating static and default routes.

Step 1: Configure static routes on Central.

a. Configure IPv4 default routes to the cloud using the Ethernet link as the preferred link and the serial link as the floating backup. Use an administrative distance of 10 for the backup route. These routes should be configured as directly connected routes.

Note: Ethernet interfaces will give a warning when configured without a next-hop address. In this configuration, the interface is point-to-point, so the warning can be ignored.

Central(config)#ip route 0.0.0.0 0.0.0.0 g0/0/2
Central(config)#ip route 0.0.0.0 0.0.0.0 s0/1/0 10

b. Configure IPv4 static routes to the Remote Branch LAN WLAN user network following the same guidelines as above for type of route and administrative distance.

Central(config)#ip route 192.168.10.0 255.255.255.0 g0/0/2
Central(config)#ip route 192.168.10.0 255.255.255.0 s0/1/0 10

c. Configure an IPv4 host route on Central to the Server-O1 on the Remote Office LAN. Create a directly connected route.

Central(config)#ip route 192.168.3.122 255.255.255.255 s0/1/1

Note: For the purpose of this assessment, please enter the IPv4 static routes in the following order:
1) IPv4 default route
2) IPv4 floating default route
3) IPv4 host route
4) IPv4 static route to Remote Branch LAN
5) IPv4 floating static route to Remote Branch LAN

d. Ensure that the device is configured to route IPv6.

e. Configure IPv6 default routes to the cloud. Use the Ethernet link as the primary route, and the serial link as the floating backup. Use an administrative distance of 10 for the backup route. These routes should specify the next hop interface address.

Central(config)#ipv6 unicast-routing
Central(config)#ipv6 route ::/0 2001:DB8:ACAD:A::2
Central(config)#ipv6 route ::/0 2001:db8:acad:b::2 10

f. Configure an IPv6 host route on Central to the Server-O1 on the Remote Office LAN It should be a next-hop route.

Central(config)#ipv6 route 2001:db8:acad:3::122/128 2001:db8:acad:d::2

Note: For the purpose of this assessment, please enter the IPv6 static routes in the following order:
1) IPv6 default route
2) IPv6 floating default route
3) IPv6 host route

Step 2: Configure static routes on Branch-101.

Branch-101 must also be configured with static routes to the other three networks in the Netacad PLC network. It will require floating static and default routes in IPv4 and IPv6 following the same guidelines as were used for the Central static routes.

• IPv6 routes use next-hop address arguments.
• IPv4 routes use exit interface arguments.
• All routes should prefer the Ethernet links over the serial link.
• Backup floating routes use an administrative distance of 10.

a. Configure IPv4 default routes to the cloud using the Ethernet link as the preferred link and the serial link as the backup.
Note: For the purpose of this assessment, please enter the IPv4 static routes in the following order:
1) IPv4 default route
2) IPv4 floating default route

Branch-101(config)#ip route 0.0.0.0 0.0.0.0 g0/0/1
Branch-101(config)#ip route 0.0.0.0 0.0.0.0 s0/1/0 10

b. Ensure that the device is configured to route IPv6.

c. Configure IPv6 default routes to the cloud. Use the Ethernet link as the primary route, and the serial link as backup. Use an administrative distance of 10 for the backup route. These routes should specify the next hop interface address.

Branch-101(config)#ipv6 unicast-routing
Branch-101(config)#ipv6 route ::/0 2001:DB8:ACAD:C::1
Branch-101(config)#ipv6 route ::/0 2001:DB8:ACAD:B::1 10

Note: For the purpose of this assessment, please enter the IPv6 static routes in the following order:
1) IPv6 default route
2) IPv6 floating default route

RTR-HQ(config)#ipv6 route 2001:db8:acad:3::122/128 2001:db8:acad:d::2

Note: For the purpose of this assessment, please enter the IPv6 static routes in the following order:
1) IPv6 default route
2) IPv6 floating default route
3) IPv6 host route

Step 2: Configure static routes on RTR-Branch.

RTR-Branch must also be configured with static routes to the other three networks in the XYZ Corp. network. It will require floating static and default routes in IPv4 and IPv6 following the same guidelines as were used for the RTR-HQ static routes.

• IPv6 routes use next-hop address arguments.
• IPv4 routes use exit interface arguments.
• All routes should prefer the Ethernet links over the serial link.
• Backup floating routes use an administrative distance of 10.

a. Configure IPv4 default routes to the cloud using the Ethernet link as the preferred link and the serial link as the backup.
Note: For the purpose of this assessment, please enter the IPv4 static routes in the following order:
1) IPv4 default route
2) IPv4 floating default route

RTR-Branch(config)#ip route 0.0.0.0 0.0.0.0 g0/0/1
RTR-Branch(config)#ip route 0.0.0.0 0.0.0.0 s0/1/0 10

b. Ensure that the device is configured to route IPv6.

c. Configure IPv6 default routes to the cloud. Use the Ethernet link as the primary route, and the serial link as backup. Use an administrative distance of 10 for the backup route. These routes should specify the next hop interface address.

RTR-Branch(config)#ipv6 unicast-routing
RTR-Branch(config)#ipv6 route ::/0 2001:DB8:ACAD:C::1
RTR-Branch(config)#ipv6 route ::/0 2001:DB8:ACAD:B::1 10

Note: For the purpose of this assessment, please enter the IPv6 static routes in the following order:
1) IPv6 default route
2) IPv6 floating default route

Part 4: Configure a Wireless LAN using a Wireless LAN Controller

In this part of the assessment, you will configure the wireless LAN controller to provide access wireless access to the network. Username and password are the default admin/admin. Connect to the WLC over HTTPS to the management interface.

Open the browser from the desktop of W-Admin Host or (Management Host). Connect to the IP address of the WLC over HTTPS: https://192.168.100.254

Login with the username admin and password admin

Step 1: Configure a VLAN interface.

a. Create a new interface and name it WLAN 10. The interface should use VLAN 10 and physical port 1.

b. Use the information in the addressing table to configure the addressing settings for the interface. The interface will be using a DHCP pool that is configured on the subinterface that is assigned to VLAN 10 on router Branch-101.

Step 2: Configure a RADIUS server.

a. Configure the WLC with the RADIUS server IPv4 address.

b. Use a shared secret of RADsecret.

Step 3: Configure a Wireless LAN.

a. Create a new WLAN. Name it WLAN 10 and configure the SSID as SSID-10.

b. The wireless LAN should use the VLAN interface that was previously configured.

c. Configure the WLAN to use the WPA2 security policy and dot1x Authentication Key Management.

d. Configure the WLAN to use the RADIUS server that was previously configured to authenticate wireless users.

e. Open the Advanced tab and scroll down to the Flexconnect sections. Activate FlexConnect Local Switching and FlexConnect Local Auth.

f. Verify that the WLAN is configured and operational.

Step 4: Configure a DHCP scope for the management network.

Configure a new DHCP scope to be used by the LAPs and other management devices on the network.

a. Name the DHCP scope Wired_Admin.

b. Start the scope at address 192.168.100.240. End the scope at address 192.168.100.249.

Step 5: Configure an SNMP server.

Configure an SNMP server to receive traps from the WLC.

a. Use the community name branch-wireless.

b. Use 172.16.1.100 as the server address.

Step 6: Configure the wireless host.

Configure the Laptop (or Wireless Host) to connect to the WLAN.

a. Create a new wireless profile on the host. Use the name work net for the profile.

Click Wireless Host Laptop and open the PC Wireless app

b. Configure the profile for the SSID of the WLAN.

c. Use enterprise authentication with a username of user1 and password of user1Pass.

d. When you are finished, click Connect to Network. It will take time for the connection to be established.
