As with unicast routing protocols, there are a number of multicast routing protocols, each with its own advantages and disadvantages. In this GateD, there will be support for:
PIM - both PIM-DM and PIM-SMDVMRP
CBT
Route passage to support Reverse Path Multicast calculationInter-Domain Tree building
This set of multicast configuration demonstrate how GateD configure within a routing domain:
# igmp yes;
# igmp yes { traceoptions "/auto/var/mcast.log" replace mtrace; } ;
If you are running PIM in the presence of tunneled DVMRP and the gated multicast kernel then PIM will try to run over the tunnel pseudo interfaces. They should be disabled as follows:
# igmp yes { interface le0 diable; interface qe0 enable; interface qe1 enable; interface qe2 disable; interface qe3 disable; };
#
# IGMP is set on
#
igmp yes;
dvmrp yes {
interface all enable;
};
igmp yes {interface le0 enable;
interface le1 enable;};
dvmrp yes {
interface le0 enable;
interface le1 enable;
};
igmp yes {interface le0 enable;
interface le1 enable;};
dvmrp yes {
interface le0 enable;
interface le1 enable advertise 192.16.5 masklen 27 metric 10;
};
igmp yes {interface le0 enable;
interface le1 enable;};
dvmrp yes {
interface le0 enable;
tunnel 192.5.8.6 lcladdr 192.5.8.7 enable;
};
Please note that the tunnel format may change in the future to more closely integrate the
tunnel functions into the interface clause.
