I pointed my NIST route at NRL, and got there in 3:

% traceroute6 5f00:3100:8106:3300:0:c0:3302:5a 
traceroute to 5f00:3100:8106:3300:0:c0:3302:5a (5F00:3100:8106:3300::C0:3302:5A), 30 hops max, 24 byte packets

Something like that, to be sure; much of IETF week is a blur to me,
but I have a vague recollection that the opposite was proposed? A
static routed core, with RIP to leaf nodes?
