This is apparently an OAM Endpoint with Punt (End.OP)

Here I'm executing ping/trace from the SRv6 ingress pe...to the egress PE

Ethernet - 86dd Ipv6 - DA fc00:0:0:4:40:: (cool, this is the active/top SID, and not the ping'ed DA) - routing header for v6 (segment routing) --- segments left: 1 --- address next segment: fc00:0:4:4::1 Icmpv6
My head hurts :-)... Mark.
