- The status page has a collapsible "Configuration" section showing the
config file as read at startup, with its path. Served by the new
GET /api/config; RouterInfo::with_config carries the text.
- Removed the AS-path prepends field and the SwissIX prepend presets
(42476:101..103) from the form to keep the exercise focused. The API
still accepts `prepend`.
- Docs follow: the handout loses its prepending exercise, the lab README
its prepend row, and the BIRD config notes that the 42476 namespace is
still admitted for hand-typed values.

Phase 5 of the teaching demo plus two fixes found while exercising the
dialer on the status page.
- Adj-RIB-In: routes learned from a peer are removed when its session ends
(RFC 4271 §8.2.2), emitting a Withdrawn event per prefix before the
session Down event. Previously stale routes from dead sessions stayed in
the received table.
- statusz: poll the peers table every 5 s so dial state (Connecting /
Backoff and its retry countdown) stays current; those changes carry no
event.
- docs/lab: docker-compose topology with ferrix (AS65000) and two FRR
routers. r2 accepts nothing directly from ferrix so student prefixes
only reach it via r1, then come back with AS path 65002 65001 65000. r1
applies community-driven policy: NO_EXPORT stops forwarding, 65001:100
prepends, BLACKHOLE drops. Dockerfile for the daemon.
- docs/lab/HANDOUT.md: student exercises walking through announcement,
reading the bytes, prepending, NO_EXPORT, action communities,
blackholing and withdrawal.
The container files have not been executed (no runtime available here);
docs/lab/README.md lists what is most likely to need adjusting.
