First, to those who have given me basic mpls, traceroute and ip primers by off list email, thank you. It's not necessary. I appreciate your willingness to help out the community. Second, I *know* that the traceroute I pasted a bit of has to do with mpls magic (or similar). That's why I used the word tunnel. I wasn't asking *how* it was done. I'm quiet capable of performing the same magic. I just wanted to know if anyone off the top of their head knew *where* the packets were magically popping back into the ether... LA, Nevada, Denver. That's all. A physical location or a router IP would have been a perfectly wonderful answer.
Hey Deepak, Sorry, but they're actually right. Read the section on icmp tunneling, it explains exactly how and why you're seeing this behavior. :) The return packets pop our at the end of the lsp, which is clearly in LA (or thereabouts, whatever lsrca is probably). -- Richard A Steenbergen <ras () e-gerbil net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
