My home connection gets IPv6 connectivity via a tunnelbroker tunnel, i
didn't use the "tunnel interface" addresses in the instructions but
configured it without addresses, traceroutes (in all directions) show
up with the routers single assigned global address.
Routers would still have a single global address assigned to loopback
(or anywhere) for management/packet generation purposes so traceroutes
should work fine, although rather than getting a per-interface address
you'll get a per-router address. What addresses do you currently get
in the real world? some routers give a loopback address, some give the
ingress interface, some give the egress interface, all you can safely
assume from the address is the router it hit.
