Routes were announced and withdrawn through an HTTP form, each tagged with a
free-text owner and checked against an allow-list and a per-owner limit.
That was the lab's interface, not a router's.
Routes now come from 'originate' entries in the configuration file and are
in the local RIB before any session starts. The local RIB holds one route
per prefix with no notion of owners or policy. local_route_policy is gone
from the configuration.
The HTTP API keeps its GET endpoints (status, config, peers, originated and
received routes, events, metrics). The announce, withdraw, wire-bytes and
well-known-community endpoints are removed, and the status page loses the
announce form, the community presets and the byte decoder. Community text
parsing moves from the web crate to bgp-packet so the configuration can use
it.

Phase 3 of the teaching demo.
- crates/web serves an embedded, dependency-free status page at /statusz
(/ redirects there). Sections: router header with live indicator, peers,
announce form (owner remembered locally, well-known community picker,
prepend / MED / large communities), local routes with per-session UPDATE
bytes segmented into header / lengths / attributes / NLRI, received
routes with rows highlighted when a locally announced prefix has come
back, and a live event log. Tables refresh on every SSE event. Light
and dark themes.
- fake_peer example in crates/integration-tests: connects, announces,
prints received UPDATEs and with --echo re-announces everything back
with its ASN prepended (dropping NO_EXPORT), so one daemon plus one
process demonstrates the full loop without lab routers.
- README for the binary documents the endpoints and the demo setup.

Phase 2 of the teaching demo: everything the status page will need is now
reachable over HTTP.
- New crate crates/web (axum). JSON endpoints for status, peers, local
routes (announce / withdraw), received routes, the exact UPDATE bytes a
local route produces per session, and well-known community names.
Communities are accepted as ASN:VALUE or by name (NO_EXPORT, BLACKHOLE,
...); large communities as A:B:C. Policy errors map to 403/409/422.
- GET /api/events is a server-sent event stream merging session up/down,
local route and Adj-RIB-In changes, with lag notifications.
- GET /metricz serves Prometheus metrics; the server crate now counts
messages sent/received by type and sessions established.
- The runnable main moves from crates/server to bin/bgp so it can depend
on both server and web without a cycle. `cargo run -- config.textpb`.
- Config gains http_endpoint; unset disables the API.
- Integration tests drive the API against a live server with a real BGP
peer, including verifying the wire view matches the bytes the peer got.
