The address on the interface given as cand_rp will be used as the primary address for your RP, it therefore must be routable. With cand_rp and group_prefix statements you can configure this router as a Rendezvous Point (RP) for your personal multicast group prefix. Also enable it for downstream network segments with multicast listeners and senders, like for example your home (W)LAN segments. Enable an interface if it is directed towards a multicast-capable peer or other multicast-capable routers in your autonomous system. The phyint statement enables PIM and MLD on the target interface - by default all interfaces are in the disable state. # configure rendezvous point for the personal multicast prefix # add multicast-capable peer interfaces below # enable the pim-router-id interface first to acquire the correct primary address Post-up ip -6 a a fd00:2001:db8::2/128 dev $IFACEĬreate the configuration file: # /etc/nf # disable all interfaces by default Post-up ip link set multicast on dev $IFACE Pre-up ip link add name $IFACE type dummy Example: # /etc/network/interfaces.d/pim6sd Also set "multicast on" on this dummy interface. This one needs to be reachable from within dn42.
The following guide illustrates how to set up an IPv6 multicast router using PIM-SM (Protocol Independent Multicast in Sparse Mode) with your own personal multicast prefix.
