I decided to look the other way around, that is to look for Internet2 R&E (AS11537) in commodity Internet paths, and after excluding some routes originated by Internet2 for Internet2 infrastructure prefixes, I get the following;

*  128.23.0.0/17      146.57.255.243                130      0 11164 6461 81 11537 2721 13429 i
*                     184.105.19.9          2095    100      0 6939 6461 81 11537 2721 13429 i
*>                    206.108.255.75           0    130      0 6461 81 11537 2721 13429 i
*> 130.127.0.0/16     206.108.255.75           0    130      0 6461 81 11537 2721 2722 12148 i
*  184.164.228.0/24   208.116.156.129        110    100      0 3257 174 5719 3754 11537 22388 24489 24489 24489 24489 24490 24490 24490 24490 24490 7575 47065 i

*> 2610:d0::/32       2001:504:27::193d:0:1
                                               0    130      0 6461 6057 1797 27750 11537 20965 24490 24287 7660 3943 i
*                     2607:ea00:0:26::2
                                             751    130      0 11164 6461 6057 1797 27750 11537 20965 24490 24287 7660 3943 i

184.164.228.0/19 is a peering research prefix, so maybe those are intentional, not sure;

https://peering.usc.edu/

At least there is an IPv6 route on this list. 😀 

I think it is a Cisco IPv6 LISP experiment. However, given that the path has Uruguay, RedClara, Internet2, GEANT, TEIN2, and Japan all in the path I'm not sure its a good idea for this route to be leaked, let alone even to be in the Internt2 R&E route table in the first place. I have a number of better routes for this prefix from the commodity Internet.

Thanks
