As you’ve noticed I’ve been studying SSM and what better way to learn than to blog about it. I recently got a Safari subscription which has been great so far. I’ve been reading some in the book Interdomain Multicast Routing:
Multicast – SSM mapping
This is a followup post to the first one on SSM. The topology is still the same. If you want to find it in the documentation it is found in the IGMP configuration guide I guess the reason to place
Source Specific Multicast (SSM) and IGMP filtering
Regular multicast is known as Any Source Multicast (ASM). It is based on a many to many model where the source can be anyone and only the group is known. For some applications like stock trading exchange this is a
Followup on multicast helper map
I had some requests for the final configs so I have fixed those. You can download them here. Also I had some issues getting the traffic through but thanks to my helpful readers like zumzum I now have it figured
Multicast helper map and how to verify multicast
The multicast helper map is an interesting feature. It can be used in scenarios where we want to transport broadcast. Routers don’t forward broadcast by default but we can convert this to multicast and transport it across our network and
Common misconceptions about the ip mroute command
Almost all of us know the difference between a static route and a dynamic one, longer match wins. If same length then AD decides and so on. I have noticed that there are some misconceptions about the equivalent to ip
Flash cards – multicast added
Added some multicast content to the flash deck. There is now a total of 151 questions in the deck. The next section that will be added when I have finished the labs is MPLS VPN. As usual, the deck is
Troubleshooting multicast – RPF failure
In unicast routing we are interested in how to forward packets to their destination. In multicast routing we are interested where the source came from, multicast packets need to pass a RPF (Reverse Path Forwarding) check. Packets that are received
