From 1d30f6120a6c17da7059a63d136b9b58a796992d Mon Sep 17 00:00:00 2001 From: Lucas Alvares Gomes Date: Wed, 5 Feb 2020 11:23:36 +0000 Subject: [PATCH] Change the default multicast group range The 224.0.0.X range is a special range in multicast which acts like a broadcast for non-IGMP traffic. This patch changes the value of the multicast_group_range configuration option to 225.0.0.X to avoid this special case. See session "2.1.2. Data Forwarding Rules" at https://tools.ietf.org/html/rfc4541 for more information: 2) Packets with a destination IP (DIP) address in the 224.0.0.X range which are not IGMP must be forwarded on all ports.
