Redundant Wireless Bridge

Hello,
We have 4 SXT Lite5 devices. 2 on one building (call it A1 and A2) and 2 on another building (call it B1 and B2). We want to make redundant wireless links in bridge mode. I mean that if the connection between A1 and B1 fails, we need A2 and B2 to resume the connection automatically. how can this be done ?

Thank you

At least 2 ways you can do it, a reliable one that comes to mind is a pair of routed links. A1 to B1 and A2 to B2 each with a unique /30. You can then use OSPF to let the networks talk and you’d gain the advantage of being able to do ECMP. This would potentially let traffic from both links through the link.

If you wanted to bridge them, create a bridge interface on each and do the dynamic-mesh mode of WDS with ether1. The only trick with that is if you include an Ethernet interface in the bridge and the A side or the B side you have to remember those links from a STP perspective when you are determining which link will be inactive. Additionally, I’d imagine you’d want the 4 SXT’s to be able to see each other wirelessly although I’m not certain that’s a requirement.

Read it and weep for joy.

I have same problem… in bridged network is there any way to make backup link ? I mean both interface will be in bridge ether1,ether2 and if link1(eth1) down it will continue from link2(eth2).
