To add eth3 to the LAN bridge br0, use this command:
configure
set interfaces bridge br0 member interface eth3
commit
save
This will add eth3 as a bridge member alongside eth0, making both interfaces part of the 192.168.51.0/24 LAN network.
Verify the Configuration
After committing, verify with:
show interfaces bridge br0
You should see both eth0 and eth3 listed as member interfaces.
Check Bridge Status
show bridge
# or
show bridge br0
This will display the bridge members and their status.
Note: Make sure eth3 doesn’t have any conflicting configuration (like an IP address assigned directly to it). Bridge member interfaces should not have their own IP addresses – the bridge itself (br0) has the IP.
