Lab 3: Configuring HREAP

Topology Diagrams

Scenario

In this lab you will use the tools available to set up and monitor APs at a remote

site. HREAP allows the remote AP to provide local service when the link to the

WLC is broken.Note: Where addresses are shown as 172.x.c.d, replace x with a value

determined by the pod. WLC1 = 16, WLC2 = 17, WLC3 = 18, WLC4 = 19.

Step 1

Set up the topology as shown. The main section should be configured the same

as Labs 1 and 2.

Step 2a – For Standalone WLC

Add router R1 and set up a layer 3 link between the router and the switch using

172.x.40.0/24.

For the serial interface, use 192.168.100.0/30. On the DCE end of this link, set

the clock rate to 1Mb/s.

Configure EIGRP routing on the switch and router. Do not include VLAN50 in the

network range. All VLANs should be passive interfaces.

Step 2b – For WLC Module

Use a serial interface on the router, and use 192.168.100.0/30 on this to a

second router. On the DCE end of this link, set the clock rate to 1Mb/s.

Configure EIGRP routing on this router. Do not include VLAN50 in the network

range. All VLANs should be passive interfaces.

Step 3 – Configure the Branch Router

Configure the serial link to operate correctly with the main router as per step 2.

Set up a trunk to the switch with two VLANs, 150 and 160, using 172.x.150.0/24

and 172.x.160.0/24. The router subinterfaces should use .1 addresses.Set up two dhcp pools for VLAN 150 and 160. Add option 43 and 60 to VLAN 150,

using the AP Manager address (172.x.1.101) as the option 43 information.

Set up EIGRP routing, making the Ethernet interfaces passive.

Step 4 – Configure the Branch Switch

Set hostname, login names and passwords.

Configure the interface to the router as a trunk.Configure the interface for the AP as a trunk.

Select WIRELESS > All APs and select the AP to be set up as HREAP.

Set the AP Name and location and change the AP mode to H-REAP.

Apply the changes using the Apply button.

Step 6 – Create and Setup the WLAN

Enable the WLAN by checking the Status check box in the General tab

Set up security

Enable local switching by checking the H-REAP Local Switching check box in

the Advanced tab.

Apply and Save Configuration.

Assign the WLAN to the local VLAN on the Wireless

Step 7 – Test the Network

Connect to the wireless network and determine that the client has the correct ipaddress and access to the correct networks.

Note: The original WLANs should still also be available.

Disable the serial link and ensure that the client still can access the local

network.

Note: The original WLANs should not be available.
