Hello, So using QFX10K as P core, it seems 6PE traceroute handling is broken (15.1X63-D65).
QFX10K configured typically as a Juniper P box, and to get it to respond to traceroute in 6PE environment, I have the following config below (pasted below). Basically, you configure family inet6 on core/PE facing interfaces so LSR can source icmp using the core-facing interface's v6 address in a 6PE setup. This works fine on MX. It appears that on QFX10K, the box is attempting to pop labels and use inet6.0 unicast routing table to send ttl-expired? Seems like icmp-tunneling is broken for v6..? o_O Anyone else seeing similar issues? Nothing surrounding icmp or 6pe issues when doing quick PR searches for 15.1X.
