1. Scope of the work

                       To disable router mode and enable brigdemode in RPI Router . It means, by default device will be in router mode. Once changed to bridge mode , Private WIFI will stop its broadcasting, Ethernet Client should get public IP address (in erouter series)  and Wireless client will lose its connection to private WIFI.

2. Target Audience  

  • RDK-B Operators
  • RDK-B SoC Vendors
  • RDK-B OEM's
  • RDK-B Application Vendors
  • RDK-B System Integrators 

3.  High level Code Flow Design

3.1. After boot-up

         


3.2. During boot-up

             

4. Supported device  

  • Raspberry Pi4 32 bit
  • Raspberry Pi4 64 bit

5. Build Instructions

Target Yocto version Build instruction
RPI4 32bit Dunfell  RPI 4B Model Reference Platform
RPI4 32bit Kirkstone kirkstone RDK-B RPI4 32 bit
RPI4 64bit Dunfell RPI 4B Model Reference Platform with 64bit Arch

6. TR-181 Data Model Parameter of Bridge Mode

Module TR-181 DM Parameter Input Output
 CcspPandM Device.X_CISCO_COM_DeviceControl.LanManagementEntry.1.LanMode bridge-static To disable router mode functionalities and enable bridge mode functionalities in RPI Router. It means ,Private WIFI will stop its broadcasting, Ethernet Client should get public IP address (in erouter series)  and Wireless client will lose its connection to private WIFI.
 CcspPandM Device.X_CISCO_COM_DeviceControl.LanManagementEntry.1.LanMode router Change from bridge mode to router mode and verify basic functionality is working fine like internet connectivity for wifi and ethernet clients and also verify admin ui page is accessible.


7. Test Procedure

7.1. Enabling BridgeMode via dmcli 

          To enable bridge mode run the following dmcli commands,

dmcli eRT getv Device.X_CISCO_COM_DeviceControl.LanManagementEntry.1.LanMode
dmcli eRT setv Device.X_CISCO_COM_DeviceControl.LanManagementEntry.1.LanMode string bridge-static

7.2. Enabling BridgeMode via WebUI

Follow the below steps to enable the bridge mode in UI,

1. Open the RPI Router User Interface on web browser

2. From the left-hand column, select "Gateway -> At a Glance"

3. Next to "Enable Bridge Mode", click Enable.

Once the RPI is in bridgemode , below test cases are needs to be passed,

  • brlan0 will lose IP address
  • A new bridge is created lan0(interface link llan0) which will have 10.0.0.1 ip address
  • Private WiFi should stops broadcasting
  • Ethernet (lan) clients should get Public IP address(i,e in erouter ip series)
  • Verify whether the admin UI page is accessible by using 10.0.0.1 ip in ethernet client device 
  • Changing from bridgemode to router mode and verify basic functionalities are working fine like Private WiFi should be broadcasted, able to get ip & internet access for wifi and lan clients and admin UI also accessible in connected clients. 

8. RPI Test Results

8.1. Router → Bridge-Static 

  1. Changing the LanMode from router to bridge-static mode

         

         2. A new bridge is created lan0(interface link llan0) which will have 10.0.0.1 ip address

         

         3. Private WiFi should stops broadcasting

         

         4.Ethernet (lan) clients should get Public IP address(i,e in erouter ip series)

           

        5. Verify whether the admin UI page is accessible by using 10.0.0.1 ip in ethernet client device 

           

        6. brlan0 shouldn't have  IP address

           

8.2. Bridge-Static → Router

  1.  Changing the LanMode from bridge-static to Router Mode

         

       2. lan0 and llan0 interfaces should be deleted

       

        3.Private WiFi Should be broadcasted

         

        4. WiFi and Lan connected clients should get IP address and internet access

         

        5.Admin UI should be accessible via connected clients.

           

        6.brlan0 should have IP address
