IGMP (Internet Group Management Protocol) and MLD (Multicast Listener Discovery) snooping are implemented in the bridge driver in the Cumulus Linux kernel and are enabled by default.

Jan 22, 2013 · Based on the fact that tcpdump in the guest sees the bridge induced igmp queries but never sees response from the kvm host running fence_virtd unless tcpdump puts the bridge into promiscuous mode or snooping is turned off, it seems as though one problem with bridge snooping is that it is not sending the igmp queries to the host running the bridge. Apr 12, 2017 · the target MAC is a broadcast or a multicast address. In this case, the frame is passed to the br_pass_frame_up() function. A VLAN-related check is optionally performed. The socket buffer is attached to the bridge interface (br0) instead of the physical interface (eth0), is evaluated by Netfilter and sent back to netif_receive_skb(). It will go through the four steps a second time. brctl setmcsqc sets the 'multicast startup query count' to . brctl setmclmi

the VLAN ID which is known to have members of this multicast group. bridge mdb delete - delete a multicast group database entry¶ This command removes an existing mdb entry. The arguments are the same as with bridge mdb add. bridge mdb show - list multicast group database entries¶ This command displays the current multicast group membership table.

The bridge is a logical interface with a MAC address and an MTU (maximum transmission unit). The bridge MTU is the minimum MTU among all its members. By default, the bridge's MAC address is the MAC address of the first port in the bridge-ports list. The bridge can also be assigned an IP address, as discussed below.

The arguments are the same as with bridge mdb add. bridge mdb show - list multicast group database entries¶ This command displays the current multicast group membership table. Linux is, of course (you doubted it?), full Level-2 Multicast-Compliant. It meets all requirements to send, receive and act as a router (mrouter) for multicast datagrams. If you want just to send and receive, you must say yes to "IP: multicasting" when configuring your kernel. Jun 03, 2016 · interfaces to the bridge just created. $ ip link set eth0 master br0 $ ip link set eth1 master br0. Now, you can create an IP address on the bridge host, so it can be addressed on the network: $ ip address add 192.168.1.100/24 dev br0. If you’d like to see the configuration of the bridge, use this command: Mar 14, 2018 · Hello, I would like to ask if there is a way to block all multicast traffic coming to specific bridge in a Proxmox node. We can accomplish this at the moment with switch settings and acl. But a node level configuration would be more efficient and "dummy" for all clusters regardless networking I am trying to set up a Linux bridge with 2 ethernet interfaces and cannot get it to work correctly. I am using Gentoo Linux and thought it would be quite easy but I end up having trouble getting packets go through the bridge. All of that is virtualized under Hyper-V is that matters for anything (but I doubt it). Here goes my configuration.
