ip-maddress - multicast addresses management SYNOPSIS
ip [ OPTIONS ] maddress { COMMAND | help } ip maddress [ add | del ] MULTIADDR dev NAME ip maddress show [ dev NAME ] DESCRIPTION
maddress objects are multicast addresses. ip maddress show - list multicast addresses dev NAME (default) the device name. ip maddress add - add a multicast address ip maddress delete - delete a multicast address These commands attach/detach a static link-layer multicast address to listen on the interface. Note that it is impossible to join protocol multicast groups statically. This command only manages link-layer addresses. address LLADDRESS (default) the link-layer multicast address. dev NAME the device to join/leave this multicast address. SEE ALSO

RDMA_JOIN_MULTICAST(3)					   Librdmacm Programmer's Manual				    RDMA_JOIN_MULTICAST(3)

rdma_join_multicast - Joins a multicast group. SYNOPSIS
#include <rdma/rdma_cma.h> int rdma_join_multicast (struct rdma_cm_id *id, struct sockaddr *addr, void *context); ARGUMENTS
id Communication identifier associated with the request. addr Multicast address identifying the group to join. context User-defined context associated with the join request. DESCRIPTION
Joins a multicast group and attaches an associated QP to the group. RETURN VALUE
Returns 0 on success, or -1 on error. If an error occurs, errno will be set to indicate the failure reason. NOTES
Before joining a multicast group, the rdma_cm_id must be bound to an RDMA device by calling rdma_bind_addr or rdma_resolve_addr. Use of rdma_resolve_addr requires the local routing tables to resolve the multicast address to an RDMA device, unless a specific source address is provided. The user must call rdma_leave_multicast to leave the multicast group and release any multicast resources. After the join opera- tion completes, if a QP is associated with the rdma_cm_id, it is automatically attached to the multicast group when the multicast event is retrieved by the user. Otherwise, the user is responsible for calling ibv_attach_mcast to bind the QP to the multicast group. The join context is returned to the user through the private_data field in the rdma_cm_event.
