T2080 Routing

Hello,

I have been working with the T2080RDB board and am trying to configure a bridge between two disconnected networks

After enabling the board I successfully create a bridge with the following commands:

brctl addbr br0

brctl addif br0 fm1-mac10 fm1-mac3

ip link set fm1-mac10 up

ip link set fm1-mac3 up

ip link set br0 up

ip addr add 192.168.1.60/24 brd + dev br0

I now have full communication between the device connected through fm1-mac10 and fm1-mac3. I am trying to initialize this bridge un boot up automatically. I have been editing the /etc/network/interfaces file, which looks like so:

# The loopback interface
auto lo
iface lo inet loopback

auto br0
iface br0 inet static
address 192.168.1.60
netmask 255.255.255.0
bridge_ports fm1-mac3 fm1-mac10
bridge_stp off
bridge_fd 0
bridge_maxwait 0

This should, by everything ive researched online, initialize a bridge on boot up but it has not been successful thus far. I tried adding the following lines to the /etc/network/interfaces file to see if anything changed but everything remained the same on boot up:

auto fm1-mac10
iface fm1-mac10 inet manual

auto fm1-mac3
iface fm1-mac3 inet manual

Any help on this matter would be much appreciated as I do not know what else to try

Thanks in advance!

Best,

Matias Lirman

Hello Matias Lirman,

Please refer to the following content of /etc/network/interfaces.

# The loopback network interface

 auto lo br0

 iface lo inet loopback

 

 # Set up interfaces manually

 iface fm1-mac3 inet manual

 

 iface fm1-mac10 inet manual

 

 # Bridge setup

 iface br0 inet static

    bridge_ports fm1-mac3 fm1-mac10

        address 192.168.1.60

        broadcast 192.168.1.255

        netmask 255.255.255.0

        gateway 192.168.1.1

Please rebuild package init-ifupdown into rootfs filesystem.

$bitbake init-ifupdown -c cleansstate

$bitbake init-ifupdown -c patch

Go the folder build_t2080rdb/tmp/work/ppce6500-fsl-linux/init-ifupdown/1.0-r7/interfaces, please modify the file interfaces as mentioned above.

$bitbake init-ifupdown

$bitbake fsl-image-core


Have a great day,
TIC
