[HECnet] HECnet performance....

[Peter Lothberg]

I'm now trying to get the Multinet links to
192.108.200.211 59.58 (STUPI) cleaned up and re_established,
right now only the link to Legato is working properly. SG1
had cost 1 on their side instead of 10.

On VMS systems anyway, LAN circuit costs are set to 4 by default.   I
always set Multinet circuit costs to 1 or 2 depending on whether it is
the preferred route or the alternate route.   I would prefer to favor the
Multinet Tunnel circuits over the bridge links.   They can be anywhere
between 4-10 times faster for file copy operations.
This is why SG1:: circuit costs are "1" in your case.

With the lack of metrics working for real on the bridged ethernet,
here is what hapens...

stupi->sg1(cost1)-<bridge(cost1) Everyone else sees area 59   with cost 2

Johnny wan't to put the cisco in Uppsala in area 1, well, then all
traffic to aread 59 will go through your box and the multine tunnel.

Without proper metrics on the bridged ethernet, the best I can think
of is that we use the bridged ethernet as primary and the multinet and
cisco tunnels as secondary (backup) traffic paths for nodes that are
multihomed. 

You need to change the cost to 10 for me to be able to turn the
tunnel back up, as I have in practice infinite BW to Uppsala.
