Stephen:

You are correctly pointing the prefix to Cisco, who in turn has a 
static route to ESnet for 5f01:2500:83e1::/48.

From ESnet it looks like I can't reach any of the FNAL hosts either,
Status: RO

I tried all 4 of them that I know of. We'll follow up w/FNAL.

root@esnet-v6r1 795 : traceroute6  5f01:2500:83e1:0:1:40:b40:728b
traceroute to 5f01:2500:83e1:0:1:40:b40:728b
(5F01:2500:83E1::1:40:B40:728B), 30 hops max, 24 byte packets
 1  * * *
 2  * * *
...


Thanks for letting us know.
