docs/lab/handout/handout.tex, typeset with Springer's LNCS class (title
block, abstract and keywords, figure, booktabs tables, RFC references), six
A4 pages so it prints double-sided on three sheets. The built PDF is
committed alongside for printing.
Three sections students work through with the slides:
1. Who holds which addresses: whois their own /48 and ethz.ch's prefix in
the RIPE database, then compare with what is actually routed.
2. Announcing the prefix on the lab page, reading the UPDATE bytes, finding
it from outside, and reaching it.
3. Steering with communities until the prefix is reachable only from the
university network (AS559 via the SwissIX route servers), with
reachability checkboxes for laptop and phone at each step.
Plus a one-page reference appendix: IPv6 notation and hex, the UPDATE
layout, path attributes, glossary.
The lab host, the lab address space and the prefix pattern are macros at
the top of the file. Expected answers were checked against the RIPE
database and RIPEstat (ETH: 2001:67c:10ec::/48, ASSIGNED PI, origin AS559;
lab: 2a0d:d741::/40, AGGREGATED-BY-LIR, route6 origin AS210036).
