[strongSwan] Is multicast-routing (by enabling PIM-SM/PIM-DM) supported directly on the XFRM-Interfaces Or is it possible to use the "forecast" plugin-feature to do the multicast forwarding on the IKEv2-IPsec Tunnel (using xfrm-interface)

[Noel Kuntze]

Hello Rajiv,

Should work fine with XFRM interfaces. AFAIR I tested something like that but with OSPF some time ago and it worked.
You better test it first though with your specific software.

Kind regards
Noel
