<div> </div>
<div>I'm trying to implement FRR into a productive multicast network which uses source specific Multicast in PIM Sparse Mode. Therefore I don't have any rendezvous points currently in my network.</div>
<div>Looking in the documentation and wiki of FRR I can't find an 100% answer if source specific Multicast with PIM-SM is currently supported by FRR.</div>
<div> </div>
<div>In the documents it looks like you have to configure a RP to make it work:</div>
<div>"In order to use pim, it is necessary to configure a RP for join messages to be sent to. Currently the only methodology to do this is via static rp commands. All routers in the pim network must agree on these values." (http://docs.frrouting.org/en/latest/pim.html)</div>
<div> </div>
<div>In some Git document I found a table <span style="font-size:11px;">"Supported Protocols vs. Platform" which states SSM (Source Specific) as supported. </span></div>
<div>(https://github.com/FRRouting/frr/blob/master/doc/user/overview.rst)</div>
<div> </div>
<div>I tried to enable it and got the following error on debug level:</div>
