5671RE: [BPQ32] missing alias in nodeslist - was: routing incorrect

      A couple of possibilites.
      Some XNET nodes sometimes send routing updates without an Alias.
      Or, if you get connect request from a node that isn't in your nodes list, it wll be added, but the alias isn't known.

      Probably related to this, since they seem to occur simultaniously. I often notice that some stations are missing their alias in the nodeslist. Like for instance at the moment of writing XnYSM:PI1YSM-10 is listed as merely PI1YSM-10 on Sergej's UT1HZM-5's nodeslist. Some other stations are missing their alias too.

      When I see this I can be sure that the link to Sergej fails and that some XNet servers have "taken over" the routing path. As said: restarting the node solves this connectivity problem and missing alias problem. And the common denominator in both problems is XNet node...

      One last remark. I had links to Xnet nodes (VE2PKT and PI1DXC) and then this problem never occurred. It started when I openend an AX/UDP link to PI1YSM-10 that is a XNet node. Not necessarily putting the blame there, nor on XNet nodes, but on the inter operation between BPQ and (some) XNet nodes.
