Also, it works with these explicit paths as well... learned a few things here, you can blackhole your traffic if you don't know your SID's... I used an adjacency sid from my previous eve-ng lab on my diagram, and I forgot that I had moved to a new lab, when I stood up the new lab, the adjacency sids were different, 24001 instead of 24002 on my of my transit links...between r24 and r23...
All these explicit paths work... all prefix/node sids... segment-list name my-srte-sidlist-2 index 1 mpls label 16024 index 2 mpls label 16023 index 3 mpls label 16022 combination of prefix/node sids and an adjacency sid... segment-list name my-srte-sidlist-2 index 1 mpls label 16024 index 2 mpls label 24001 index 3 mpls label 16022 an ip address, and adj sid, and a prefix/node sid... the ip address for the first segment is apparently is an IOS-XR trick that resolves the ip to the prefix sid of that hop... segment-list name my-srte-sidlist-2 index 1 address ipv4 10.20.0.24 index 2 mpls label 24001 index 3 mpls label 16022 an ip address a couple hops away but is in the igp direction that I desire, and adj sid on the link to the last hop... segment-list name my-srte-sidlist-2 index 1 address ipv4 10.20.0.23 index 2 mpls label 24000 all those work for my desired SRTE path... the all result in the ce traffic taking the atypical anti-igp path... some result in different mpls tagging, but, all cases end up being 3 tags and follow the correct, desired path. Here's the trace of that last sedment-list (ip to 10.20.0.23, and adj sid 24000)... ce1#traceroute 1.1.1.2 Type escape sequence to abort.
