I think it's time to come up with something a little better to track all these. Thoughts? A subdomain under some related domain (perhaps <sub>.hecnet.update.uu.se?) with the tunnel endpoints as A records? The problem here is that it isn't searchable. You need to know the A record name. It would be more useful for me to have it in a db. -brian

Need to agree on a comunity and a RO pw... Which requires "out of band" IP access. While I'm not opposed to doing that, it would be really nifty if we could do this entirely within DECnet. :) -brian

I think it's time to come up with something a little better to track all these. Thoughts? Build a tool that takes requests and generates configs (full mesh) and pushes them to the routers. (maybe we can have the router configs in a wiki?) Great mind think alike. :) I had though pretty much exactly that. If we are going to do that, however, we should decide on a range of tunnels to use. For example on my router, 0, 1 and 2 are DECnet tunnels, 3 is my IPv6 tunnel to HE and 4 is a DECnet tunnel. Re-pushing the configs in this case would be ugly, so I think it would be wise to say, tunnels X through Y are dedicated to auto-DECnet tunnels so I can write cisco configs to deal with that appropriately. I will write something. :) -brian

Peter, I was able to set the circuit cost to 10 remotely so you should be all set. -Steve ________________________________ From: owner-hecnet at Update.UU.SE on behalf of Peter Lothberg Sent: Wed 1/9/2013 09:37 To: hecnet at Update.UU.SE Cc: hecnet at Update.UU.SE Subject: RE: [HECnet] HECnet performance.... I'm now trying to get the Multinet links to 192.108.200.211 59.58 (STUPI) cleaned up and re_established,=20 right now only the link to Legato is working properly. SG1=20 had cost 1 on their side instead of 10.=20 I should add that if SG1:: and LEGATO:: need to pass information, the circuit costs favor the Multinet Tunnel links between the two major US hubs. I would rather the Multinet Tunnel be used instead of using the bridge link to Sweden and then back again. -Steve Steve, In that case you are right, and as I said before, the problem is the bridged ethernet. Multinet nodes, could increese the cost on their Ethernets, but it only works one direction, as all the remote nodes has the same metric on their Ethernet towards you. In the SG1:: LEGATO:: case you can do the local optimization as the topology and other nodes on those locations may allow it, but it's not possible to do that in area 59, and especially not if the cisco box in uppsala is in area 1 talking to area 59 with a additional hop. I'm only asking you to set your cost on the multinet link to stupi:: to 10. -P

Peter, I will set the costs to 10 for STUPI:: when I get home late this evening. -Steve ________________________________ From: owner-hecnet at Update.UU.SE on behalf of Peter Lothberg Sent: Wed 1/9/2013 09:37 To: hecnet at Update.UU.SE Cc: hecnet at Update.UU.SE Subject: RE: [HECnet] HECnet performance....
