DescriptionCommand
Reduces the leave latency for IGMPv2 hosts.
This command is not required for
configuring SSM mapping; however,
configuring this command can be beneficial
for IGMPv2 hosts relying on SSM mapping.
Note
ip igmp last-member-query-interval 100
Configures SSM mapping to be used to determine the
sources associated with group 232.1.2.1. The resulting
(S, G) channels are statically forwarded.
ip igmp static-group 232.1.2.1 source ssm-map
Enables IGMPv3 on this interface.
This command is shown in the configuration
only to demonstrate that IGMPv3 can be
configured simultaneously with SSM
mapping; however, it is not required.
Note
ip igmp version 3
Minimizes the leave latency for IGMPv3 host leaving
a multicast channel.
This command is not required for
configuring SSM mapping.
Note
ip igmp explicit-tracking
Limits the number of IGMP states resulting from
IGMP membership states on a per-interface basis.
This command is not required for
configuring SSM mapping.
Note
ip igmp limit 2
Enables the acceptance and processing of IGMP v3lite
membership reports on this interface.
This command is shown in the configuration
only to demonstrate that IGMP v3lite can be
configured simultaneously with SSM
mapping; however, it is not required.
Note
ip igmp v3lite
Enables interception of TCP packets sent to the
reserved URD port 465 on an interface and processing
of URD channel subscription reports.
This command is shown in the configuration
only to demonstrate that URD can be
configured simultaneously with SSM
mapping; however, it is not required.
Note
ip urd
Configures SSM service.
