sam 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.

gobgp-evpn — modular EVPN test-route injector

A profile-gated, non-production GoBGP instance for exercising the EVPN ingestion pipeline (roadmap E5). The CML IOS-XR lab cannot originate EVPN routes, so this container synthesises them.

What it does

gobgp-evpn runs GoBGP with no BGP peers, BMP-exporting its local RIB (route-monitoring-policy = local-rib) to the OpenBMP collector. Routes injected with inject-evpn.sh are parsed by the collector and published to the openbmp.parsed.evpn Kafka topic, where the EVPN consumer picks them up and writes the evpn_rib table.

Usage

# start the injector (not started by a normal `docker compose up`)
docker compose --profile evpn-test up -d gobgp-evpn

# push synthetic type-2 / type-3 / type-5 EVPN routes
bash gobgp-evpn/inject-evpn.sh

# inspect what GoBGP holds
docker exec obmp-gobgp-evpn gobgp global rib -a evpn

# stop it when done testing
docker compose --profile evpn-test stop gobgp-evpn

Notes

  • Local AS 65010, router-id 10.40.40.251 — distinct from the production gobgp global-table feed (AS 65001).
  • It is not part of the default stack: the evpn-test Compose profile keeps it out of production and lets it be started/stopped on demand.

Collector type-5 limitation

The OpenBMP collector 2.2.3 parses EVPN type-2 (MAC/IP) and type-3 (inclusive multicast) cleanly, but mis-decodes type-5 (IP-prefix): the IP prefix bleeds into the RD field on the openbmp.parsed.evpn topic (observed garbage RDs such as 6154:3523870730). inject-evpn.sh therefore injects only type-2 and type-3. Full type-5 support needs a newer collector or the GoBMP path — see docs/ROADMAP.md Track E (E5).
