![]() ![]() nothing wrong with that generally speaking. now the non response on hop 17 is likely just a router that is set to not respond to ping requests. On route 1, there is one small hiccup on hop 4 but in and of itself is nothing to worry about. Linux ubnt 3.10.107-UBNT #1 SMP Thu Aug 9 08:16: mips64 1 You dont want or need to do a traceroute to a local device on your network. from your tracert's, it doesnt look like your having much of an issue with the routing.

No matter the destination, it always shows upstream gateway as the final hop. ![]() On linux it works because UDP traceroute, and windows uses ICMP.Įither an engineering snafu on the MPLS (possibly relating to the IPv6 deployment) or they are intentionally blocking ICMP? I noticed that Verizon is now intercepting and breaking traceroute (on Windows) and mtr. Why is Verizon intercepting traffic and breaking things in this way? I found a thread on Verizon's forums with someone else with the same issue: For ICMP TTL to decrease in transit, MPLS must rewrite the IP packets each time, like a non-MPLS router would, as MPLS TTL decreases. The packets travel along the Verizon network for two hops and then jump to. If I use traceroute on Linux, it works: traceroute -n 8.8.8.8 For ICMP traceroute to work properly, you have to enable IP TTL Propagation in MPLS or else you get the end result that you see here since MPLS has its own form of TTL.
