From 48f8c3d212644a33dd0abaaa1a0c71d4decaafdf Mon Sep 17 00:00:00 2001 From: Xavier Simonart Date: Mon, 24 Jun 2019 17:01:54 +0200 Subject: Add support for igmp and multicast Multicast can be enabled through configuration or through command line - Through configuration Add multicast=mcast_address (e.g. multicast=01:00:5e:01:02:03) in the port section - Through command line run enable multicast port_id mcast_address (e.g. enable multicast 1 01:00:5e:01:02:03) IGMP join message is sent unsollicited through command line: join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3) To enable swap answering IGMP Query (w/ IGMP Join) - Through configuration Add igmp ipv4=ip_address within the core/task section - Through command line join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3) (this will 1st initiate an unsollicated join, then answer any subsequent query) UDP/TCP packets received on a multicast address (224.0.0.0 => 239.255.255.255) are discarded To stop sending responses to IGMP query: leave igmp core_id task_id Change-Id: I3808ccabf3b38b5a1e10e1b044db63aa05bcd7b5 Signed-off-by: Xavier Simonart --- VNFs/DPPD-PROX/task_init.h | 1 + 1 file changed, 1 insertion(+) (limited to 'VNFs/DPPD-PROX/task_init.h') diff --git a/VNFs/DPPD-PROX/task_init.h b/VNFs/DPPD-PROX/task_init.h index f513d34f..9fa9f92b 100644 --- a/VNFs/DPPD-PROX/task_init.h +++ b/VNFs/DPPD-PROX/task_init.h @@ -233,6 +233,7 @@ struct task_args { uint irq_debug; struct task_base *tmaster; char sub_mode_str[PROX_MODE_LEN]; + uint32_t igmp_address; }; /* Return the first port that is reachable through the task.
