Re: Lossy (broken?) router dist1-10g1-2.snfcca.sbcglobal.net
Norman,
Oh, so I don't have a problem? Gee.
Even the ATT techs agree that there is an issue, that they see it and they try what they can: rip+rebuild.
Do you have a suggestion on an IPSEC based trace tool?

| I did not say you don't have a problem. I overlooked your VNC comment in your original post.
All that I am saying is that the link you posted is not evidence of a problem. You need more than some "routerwatch" link, which is only showing evidence of trace route de-prioritization. Surly there are other tools, which can be used in conjunction with IPSEC, to demonstrate the problem! I don't know of any, myself, though. I've not played with VPN tunnels.
Rip and rebuild would fix a problem on your aggregation router; but it doesn't appear to be that router?

| Norman,
Yes, and no. I'm not sure what dslreports uses for trace route. It could be udp or ICMP. Even if it is ICMP pings, the fact that all other routers from the east coast to me decide to pass it along and this one has to de-prioritize them is a sign. It is not proof, I agree with you.
I'm sorry, but I don't know which are agregation routers from this path:
bb1-g1-0.pxpaca.sbcglobal.net
dist1-10g1-2.snfcca.sbcglobal.net2
rback35-g1-snfcca.sbcglobal.net

| The only sign that a router not passing trace route packets (could be UDP, TCP, or ICMP; it is the TTL flag, among other packet header data, which makes it a trace route packet) give is that it is not passing those packets. Whether that is due to problems with the router, or other, can't be determined from the trace.
I am reasonably certain that your aggregation router is 'rback35-g1-snfcca.sbcglobal.net'.
