Not the Junos config itself. I was not being specific its not from the
user hardware sites its an issue on the cogent side. The 2 peer setup
has never been stable for me with Foundry, Cisco or Juniper. Only when I
get them to give me a standard single peer setup.

Hi Manolo,
Can you point out the flaws in this comfig for me and make recommendations?
I'm not a junos expert, but I've never had any problems with this config
running a few 1Gb/s links at near capacity. I'm always looking to improve my
setup.

Be careful with this cogent setup under high load. It tends to break
quite easily. I have a long documented history of having to prove it to
cogent how bad it really is. I am glad to see cogent doesn't learn from
its mistakes.
