 # --- BMP export to the OpenBMP collector ------------------------------------
-# GoBGP connects OUT to the collector. "obmp-collector" resolves on the shared
-# compose network; port 5000 is the collector's BMP listener.
+# GoBGP connects OUT to the collector. GoBGP's BMP config requires a literal
+# IP (it cannot resolve a hostname), so we target the docker host IP where the
+# collector publishes port 5000 -- stable across container recreation, unlike
+# the collector's internal docker IP. Matches HOST_IP in .env.
 # route-monitoring-policy = "pre-policy" exports the Adj-RIB-In (received
 # routes, pre import-policy) -- consistent with the rest of the OpenBMP fleet.
