From bc83fb097719f5c4c803808572f690fbc367b9e5 Mon Sep 17 00:00:00 2001 From: Christian Breunig Date: Mon, 13 Nov 2023 12:54:25 +0100 Subject: igmp: T5736: migrate "protocols igmp" to "protocols pim" IGMP and PIM are two different but related things. FRR has both combined in pimd. As we use get_config_dict() and FRR reload it is better to have both centrally stored under the same CLI node (as FRR does, too) to just "fire and forget" the commit to the daemon.
