IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic to control delivery of IP multicasts. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission.
To diagnose problems arising from use of the Linux bridge module. Background. An Ethernet bridge (or switch) is a device for forwarding packets between two or more Ethernets so that they behave in most respects as if they were a single network. It could be a physical device, but it is also possible for a bridge to be implemented entirely in docker bridge networking: In this mode, the Docker daemon creates docker0, a virtual Ethernet bridge that automatically forwards packets between any other network interfaces 1. Create Linux Bridge on both servers, and enable it. # brctl addbr br-vx # ip link set br-vx up. 2. Create VXLAN (virtual) interface, using multicast address enable it and add it to the Linux bridge. # ip link add vxlan10 type vxlan id 10 group 224.10.10.10 ttl 10 dev eth2 # ip link set vxlan10 up # brctl addif br-vx vxlan10 . 3. The bridge multicast module will notify port netdevs on every multicast group changed whether it is static configured or dynamically joined/leave. The hardware implementation should be forwarding all registered multicast traffic groups only to the configured ports. 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.
•Many NICs also filter multicast / vlan-tagged packets by default bridge eth0 TCP/IP kernel eth0 TCP/IP bridge eth1 handler hook pass to upper layer promiscuous mode without bridge with bridge br0 if dst mac is bridge device promiscuous mode

It is also possible that Linux Bridge can be setup to bond multiple Ethernet Devices together and present them as a single interface. In some cases, this might be useful to load balance and high availability of networks. In this article we will learn about configuring a Bridge.
