5. Determine whether to locate the RP with the static configuration, BSR, or auto-RP
method.
6. Determine whether to configure multicast to use its own RPF routing table when
configuring PIM in sparse, dense, or sparse-dense mode.
7. Configure the SAP and SDP protocols to listen for multicast session announcements.
See Configuring the Session Announcement Protocol.
To configure the Internet Group Management Protocol (IGMP), include the igmp
statement:
igmp {
accounting;
interface interface-name {
disable;
(accounting | no-accounting);
group-policy [ policy-names ];
immediate-leave;
oif-map map-name;
promiscuous-mode;
ssm-map ssm-map-name;
static {
group multicast-group-address {
exclude;
group-count number;
group-increment increment;
source ip-address {
source-count number;
source-increment increment;
}
}
}
version version;
}
query-interval seconds;
query-last-member-interval seconds;
query-response-interval seconds;
robust-count number;
traceoptions {
file filename <files number> <size size> <world-readable | no-world-readable>;
flag flag <flag-modifier> <disable>;
}
}
You can include this statement at the following hierarchy levels:
•
[edit protocols]
•
[edit logical-systems logical-system-name protocols]
By default, IGMP is enabled on all interfaces on which you configure Protocol Independent
Multicast (PIM), and on all broadcast interfaces on which you configure the Distance
Vector Multicast Routing Protocol (DVMRP).
