To: "FreeBSD-Net (FreeBSD.Org) List" X-Mailer: Mail*Link SMTP for Quarterdeck Mail; Version 4.0.0 Sender: owner-freebsd-net@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Dear List Does anyone know if IGMP v1 or v2 is implemented in the FreeBSD 2.2.6 TCP/IP stack. ? I am using a FreeBSD router running DVMRP with three interfaces. A video server is hanging from fxp1 interface and a video client from fxp2. When the video client quits a video multicast group (I do not know if the client TCP/IP stack uses IGMP v1 or v2), m/c packet forwarding forwarding for the group continues for a further two minutes or so and then ceases. This sounds like IGMP v1 behaviour to me where m/c forwarding state just time-outs at router if not refreshed. But does this mean router is IGMP v1 or client is IGMP v1 (or even both ?)
