I have two 435g boards. The distance between towers is 15 miles. I have set up a backhual using wlan1 at the office and wlan3 in the country. The link between the towers is perfect. I used the “Transparently bridging two networks using MPLS” scenario. Works well no problems wonderful speeds. On the tower in the country, I have 3 sector antennas in the other slots of the RB435g. I would like to connect these three as a single ap (wds). I have tried to get it to bridge by putting the radios in the bridge with the backhaul however when I do this everything hoses up requiring me to go on site and reset the radio. I tried to set up a single sector just to check if I can connect a client and hit the office. I connect with the ap but not the office. I can plug into the ethernet and all is well. Have I missed a config issue? Routing a problem? could it be possibly faulty hardware? Does WDS not work with the MPLS scenario? Am I losing my mind as well as my hair? Any thoughts or possible config changes appreciated. Aaaargh! This has me stumped.

Thanks all!

I wouldn’t bridge it from tower 1 all the way through to the access point. The bridge from tower 1 to tower 2 is fine, but you would be better off to NAT the three sectors.

I’ve got my system configured with one subnet for the AP bridge, one subnet for the tower to tower shot, another subnet for the next AP bridge. I have my AP’s for my customers bridged per tower. Some folks disagree with that as well, they recommend a different subnet per radio.

Thanks for the response! When I try to nat the three radio’s it gives me an error

(On my office radio the grid is on wlan1)

  1. Configure the wireless access point
    /interface wireless set wlan1 disabled=no ssid=SOUTHPIPE frequency=5180 mode=bridge

2.Configure IP address
/ip address add address=172.16.100.1/24 interface=wlan1

3.Enable LDP
/mpls ldp set enabled=yes lsr-id=172.16.100.1 transport-address=172.16.100.1
/mpls ldp interface add interface=wlan1

4.Configure VPLS tunnel
/interface vpls add name=vpls1 remote-peer=172.16.100.2 vpls-id=1:1 disabled=no

5.Add bridge and bridge ports
/interface bridge add name=bridge1
/interface bridge port add bridge=bridge1 interface=ether1
/interface bridge port add bridge=bridge1 interface=vpls1


My tower out in the country after doing a full /system reset-configuration:
(On the tower in the country radio the grid to the office is on wlan3, it has sector antennas on wlan2, wlan4, wlan5 )

  1. Configure the wireless access point
    /interface wireless set wlan3 disabled=no ssid=SOUTHPIPE frequency=5180 mode=station

2.Configure IP address
/ip address add address=172.16.100.2/24 interface=wlan3

3.Enable LDP
/mpls ldp set enabled=yes lsr-id=172.16.100.2 transport-address=172.16.100.2
/mpls ldp interface add interface=wlan3

4.Configure VPLS tunnel
/interface vpls add name=vpls1 remote-peer=172.16.100.1 vpls-id=1:1 disabled=no

5.Add bridge and bridge ports
/interface bridge add name=bridge1
/interface bridge port add bridge=bridge1 interface=ether1
/interface bridge port add bridge=bridge1 interface=vpls1

I then assigned the first sector 192.168.1.1/25
Then did a route 0.0.0.0/0 and did the gateway through wlan3
Maybe this was the mistake?
If I can get the first one up and running, im sure I can figure out the others
