to stabilize, try to remove tunnels and move to IPv6 over leased
line (or IPv4/v6 dual stack connectivity over leased line). it works

you don't even need site-locals for point to point links. they just
work fine with link-local address. all routing protocols should run
fine with p2p with link-local address only.

if /35 runs out, country-wide operator can ask for more to RIR.
/35 was assigned from RIR to facilitate slow-start. country-wide
operator should be able to grow into /29 sub TLA without renumber,
then become a proper TLA (/16) - this is what I understand at this
if you use something other than /48, you will make renumber harder
for customers (universities).
