In this article I am going to configure Multicast Source Distribution Protocol (MSDP) for a BGP network. It is not so different from configuring normal MSDP in your IGP and involves configuring an extra address-family in your BGP routing.
In this article I will discuss IGMP v3 and Source Specific Multicast (SSM) with an example. As you remember from my previous post, I have enabled multicast on all routers and R01 is the RP. Here are some commands to have an initial configuration verification:
R01#sh ip multicast Multicast Routing: enabled Multicast Multipath: disabled Multicast Route limit: No limit Multicast Triggered RPF check: enabled Multicast Fallback group mode: Sparse Multicast DVMRP Interoperability: disabled
Here is a video on NSSA areas and their configuration.
A BGP community is a 32-bit number that can be attached to a prefix and sent to other ASs. It is transitive (any BGP router will pass it, whether or not it understands what to do with it) and optional (it does not need to be set).
In this article I want to talk about four community value that are mostly used.
