b480615ca2 BMP port 1790 everywhere: parameterize the published collector port (finding 12)
Decision landed: routers target 1790 (IANA BMP port); the collector keeps
listening on 5000 in-container. One .env variable now drives every hop:

- compose publishes ${ROUTER_FACING_PORT:-1790}:5000 (was hardcoded 5000:5000)
- gobgpd.conf.tmpl (+ evpn) gains __BMP_PORT__; setup.sh renders it from
  ROUTER_FACING_PORT -- gobgp is host-networked, so it must chase the
  published port or the full-table feeder silently breaks
- deploy.sh + scripts/wsl-portproxy.ps1: the WSL side now publishes the
  router-facing port itself, so the portproxy forwards the same port
  end-to-end instead of down-mapping to 5000
- cml/proxmox_bmp_config.py reads ROUTER_FACING_IP/PORT from .env (HOST_IP
  fallback for pre-key .envs); xrd-node-definition.yaml baked port -> 1790
- .env.example documents ROUTER_FACING_IP/PORT; docs updated, finding 12
  closed on the repo side (routers still on 5000 need a config re-apply)

Verified live: collector republished 0.0.0.0:1790->5000, gobgp BMP session
Up to HOST_IP:1790 with the RIB dump flowing.

2634aada24 Parameterize HOST_IP everywhere -- portable to another lab host
Removes hardcoded 10.40.40.202 references so a fresh clone + .env-only
edit can stand the stack up on a new compute node.

  * docker-compose.yml: rib-poller PG_DSN now uses ${HOST_IP:-...}.
  * obmp-rib-poller/poller.py: default PG_DSN host falls back to
    ${HOST_IP} env (compose passes it; manual runs honour $HOST_IP too).
  * cml/gobgp_peering_config.py: GOBGP_IP read from $HOST_IP or the
    HOST_IP= line in repo-root .env, with a small _env_default helper.
  * cml/proxmox_bmp_config.py: COLLECTOR_HOST resolved the same way.

For gobgp/gobgpd.conf and gobgp-evpn/gobgpd.conf -- jauderho/gobgp is
distroless (no shell), so we can't sed-substitute at container start.
Pattern instead:

  * gobgpd.conf is now gobgpd.conf.tmpl with __HOST_IP__ placeholders
    (committed). The rendered gobgpd.conf is gitignored.
  * setup.sh renders the .tmpl(s) to .conf using $HOST_IP from .env.
  * compose `command` stays the simple `gobgpd -f /config/gobgpd.conf`.

After cloning on a new host:  cp .env.example .env  -> edit HOST_IP ->
./setup.sh -> docker compose up -d. Verified locally by force-recreating
gobgp; all 6 sessions (4 cores + 2 Bromirski) re-established in <60s.

Known portability gaps still to address (separate work):
  * Hardcoded lab-router inventories in cml/*.py and
    obmp-rib-poller/poller.py.
  * The /etc/cron.d/openbmp */5 -> */15 edit inside obmp-psql-app is
    not persistent (regenerated by config_cron on every container start).

41ec96c3ac EVPN injector: drop type-5 (collector 2.2.3 mis-decodes it)
Verified against the live collector: EVPN type-2 (MAC/IP) and type-3
(inclusive multicast) parse cleanly onto openbmp.parsed.evpn, but
type-5 (IP-prefix) is mis-decoded — the IP prefix corrupts the RD
field. inject-evpn.sh now injects only type-2/3; the type-5
limitation is documented in the injector README and roadmap E5.

f7532b62ef Add modular gobgp-evpn EVPN test-route injector (roadmap E5)
A profile-gated GoBGP instance (Compose profile 'evpn-test', not part
of the normal stack) that originates synthetic BGP EVPN routes and
BMP-exports its local RIB to the collector. Verified end to end: the
injected type-2/3/5 routes are parsed by the collector and land on
the openbmp.parsed.evpn Kafka topic, ready for the EVPN consumer.

inject-evpn.sh pushes type-2 (MAC/IP), type-3 (inclusive multicast)
and type-5 (IP-prefix) routes. Start with:
  docker compose --profile evpn-test up -d gobgp-evpn
