As soon as one interface becomes more loaded than the other, what decision process are you going to make to move only a small amount of traffic to the other interface? If you don't do this in small steps, then you will surely experience an oscillation between the two (or three) interfaces as the lowest load interface immediately becomes the highest loaded interface due to the decision to send traffic that way instead. Also, remember that not only do you have to make the decision on your side, but you also must let your peers know that you want your incoming traffic to move also. So you now must have some method of advertising your desires to the rest of the world. Currently your best choice is to manually develop route-maps which will balance both incoming and outgoing traffic on each interface. I definately have some thoughts on the above idea, and how something like that may be accomplished, but they are so very undeveloped that this is not the time or place to display my lack of knowledge. I'd prefer to put it all down on "paper" somewhere and then submit the idea if anyone who really understands all this is interested. I'm sure none of my ideas are original. Chris A. Icide Nap.Net

The NANOG list has been uncharacteristically quiet as of late... just checking to see if you are all still alive.

If your bad luck is ATM luck it can't be all bad. Try at least 11.1.6, and run the aip20-9 microcode load. You may have to open a ticket to get the microcode image. It never hurts to have Cisco check the rev levels of *all* cards in your router for possible interactions.

If you have any DVMRP tunnels on these systems watch out for BUG 77855. It is in 11.1(6), 11.1(7), 11.2(1) and 11.2(2). Our router was crashing after about 20 hours. ID: 77855 Feature-set: queuing Title: I/O Memory Leak caused by bw > 2048 on tunnel interface Reported: 11.2(1) 11.1(6) Integrated: Severity: 2 State: R I/O memory on a system can start leaking and deplete if a tunnel interface is configured together with a bandwidth greater than 2048. Symptoms are the display of sys-2-malloc failure error messages. --Tom Hutton San Diego Supercomputer Center

Problem: The number 1829 is an Autonomous System NUMBER (ASN) in use by the Los Alamos National Laboratory associated with an Autonomous System NAME (ASN) called NOTES. So, you can't have it.

HOW DO I GET IP'S?
by WING System Administration 10 Dec '96

10 Dec '96

Can anyone suggest a good way to get a CIDR block from the internic? We are two separate isps with separate ASNs, merged under one corporation, with one of them currently getting addresses from an upstream provider (/20). The problem is that in that location we are out of addresses, are multi-homed, and dissatisfied with our current provider. We need addresses before we can switch over, but the internic refuses to release any to us until we have used another /20 from our current provider. Thus, the internic has forced us to use one carrier with poor service. Legally, is this a monopoly? Has anyone started a class action suit? Can anyone help us? ________________________________ WING - Wilder InterNet Gateway admin(a)id.wing.net ________________________________
