Mar 30, 2020 · mDNS, or multicast DNS, is a way to discover devices on your network at .local domain without any central DNS configuration (also known as ZeroConf and Bonjour, etc). Fedora Magazine has a good article on setting it up in Fedora, which I won’t repeat here. If you’re like me, you’re using OpenWRT with multiple VLANs to separate networks.
The Linux kernel is Level-2 Multicast-Compliant and meets all the requirements to send, receive, or act as a router for multicast packets or datagrams. The default kernels for Red Hat and Fedora are compiled to support multicast transmission. Multicasting begins with an application requesting multicast group membership. I too am struggling to get my YouView box working with BT's multicast internet channels. Just bought a TP-Link Archer C7 and immediately updated the firmware to OpenWrt. TP-Link TL-WDR3600 v1.5 (ar71xx) EE Brightbox 1/Arcadyan AR7516 (BCM63xx) MK RB750r2 - OpenWrt Snapshot ar71xx D-Link DIR-615 D2 - OpenWrt (ramips/rt305x) Hi, I think that enabling multicast routing on latest Kamikaze is a good idea cause now plenty of ISP are also providing iptv and many of them are using multicast. if you want to get multicasts in lan in an convinient way openwrt should have multicast routing enabled in the kernel, but it has not. When I send multicast from station A on 2.4GHz and do a tcpdump on station B on 2.4GHz as well as on OpenWRT on 2.4GHz, I see some packet loss on station B, but a multiple of packets on OpenWRT. Seems like about 50% more packets are received by an interface-specific tcpdump running on the 2.4GHz interface on OpenWRT, than are actually
研究了下 IGMP Snooping 这个东西，OpenWRT 官网是这么说的： When a host wants to start receiving UDP multicast traffic, it needs to subscribe itself to a "UDP multicast group". Control of multicast groups is archived with IGMP protocol. Once a host is subscribed, all the traffic for this group is sent to it using broadcast L2 frames.
Multicast and relay bridge Post by tapir » Fri Dec 13, 2013 11:59 am I was using OpenWRT with relayd to connect 2 routers via wi-fi and connect clients via cables to the routers.

The latest stable version of OpenWrt comes with linux 3.18.23 # uname -r 3.18.23 After executing bridge mdb add dev br-lan port eth0.1 grp 239.0.0.0 temp on OpenWrt, multicast packets to 239.0.0.0 are routed from br-lan 192.168.1.1 to 192.168.1.2.
Currently I have the below eth5 to receive multicast data for 239.1.1.31. It works. $ ifconfig eth5 Link encap:Ethernet HWaddr E4:11:5B:94:E1:F3 inet addr:10.185.2.2 OpenWrt (OPEN Wireless RouTer) is an open source project for embedded operating systems based on Linux, primarily used on embedded devices to route network traffic. The main components are Linux, util-linux, musl, and BusyBox.
