What is IP Multicasting? Concept of IP Multicast Address
mcast-tools download | SourceForge.net Mar 22, 2013 Multicast: From Theory to Practice | Linux Journal When multicast was implemented, the sockets layer was extended a bit to support it. That support came via the setsockopt / getsockopt system calls. Three of the five new optnames (see the setsockopt man page) were intended for use when sending data: IP_MULTICAST_LOOP, IP_MULTICAST_TTL and IP_MULTICAST_IF. They are all at the IPPROTO_IP level.
Hi Guangming, Assuming that your 4500X is running multicast routing, you could try entering the show ip mroute command to show the multicast routing table. If you are using PIM-DM or PIM-SM, you will probably see entries of the (S,G) form where S is the IP address of the source of a multicast stream, and G is the IP address of a multicast group.
unicast or multicast; universally administered addresses (UAA) or locally administered addresses (LAA) I have a generic PC with the motherboard providing the one and only network port and the network cable is unplugged and this is on CentOS 7.6. I can read the info at wikipedia on the matter but it … Solved: how to trace the source of a multicast - Cisco Hi Guangming, Assuming that your 4500X is running multicast routing, you could try entering the show ip mroute command to show the multicast routing table.

linux - listing multicast sockets - Stack Overflow In addition to netstat -g you can use this to see all sockets which are bound to a multicast address:. netstat -anu|sort -nk4 This is a list of all UDP sockets (whether multicast or not). Look for all addresses in the range 224.0.0.0 to 239.255.255.255. Multicat - the multicast swissknife - VideoLAN It is designed to run on Linux, FreeBSD and Mac OS X. The multicat program. multicat itself is a 1 input/1 output application. Inputs and outputs can be network streams (unicast and multicast), files, directories, character devices or FIFOs. It is thought to be a multicast equivalent of the popular netcat tool. multicast | Data Distribution Service (DDS) Community RTI Note: Applies to NDDS 3.x, RTI Connext 4.x and above. The LynxOS 4.0 IP stack (and many other BSD-derived network stacks) will fail to send multicast messages unless there is an entry in the routing table that matches the destination multicast IP address. In practice, this means that either: a Multicast over TCP/IP HOWTO: Multicast Explained.
