STP was enabled. I also couldn't think of a place for a L2 loop to exist. Doesn't mean there wasn't one. CDP was disabled. I punted. We happened to have our first RB750G test unit show up yesterday. I put it at the tower and brought up OSPF from the office to the RB750G across the ubiquity link. Then I configured the necessary static routes on the RB750G. Looks good for the most part. We have much better throughput and latency. I do have one left over problem. We have a StarOS vtun from the office to the OSPF network we are merging in 4 (OLSR) wireless hops away. The tunnel has always been a bit flakey, but now, it doesn't seem to want to pass traffic for very long. It stayed up for the longest period while I had a ping per second running across the link for a couple of hours. But shortly after I kill the ping, it fell down again. StarOS 1.4.22mumble. I don't have enough data to know if the vtun forgets to pass traffic when it goes "idle" or if it was just luck. StarOS never recognizes that the tunnel is broken. It just doesn't pass IP. Nothing in the logs. We have a handful of vtuns to provide redundant paths across the OLSR wireless net to non-wireless gear which cannot speak OLSR in various locations. They've always been a bit of a pain. They take minutes to fail down which slows OSPF routing around the problem. But, now I'm fed up. It's not ubiquitous enough for a multi-vendor ISP network. And it's cost me half of Field Day weekend... That's the last straw.
