Igmp Configuration Examples; Basic Igmp Functions Configuration Example - HP A6600 Configuration Manual

To do...
Display the multicast group
information created from IGMPv1
and IGMPv2 reports based on the
configured IGMP SSM mappings.
Display information about the
hosts that join the group based on
IGMP SSM mappings on an
interface.
Remove all the dynamic IGMP
group entries of a specified IGMP
group or all IGMP groups.
Remove all the dynamic Layer 2
port entries of a specified IGMP
group or all IGMP groups.
Clear IGMP SSM mappings.
The reset igmp group command cannot remove static IGMP group entries.
The reset igmp group port-info command cannot remove the static Layer 2 port entries of IGMP groups
IMPORTANT:
The reset igmp group command can cause reception of multicast data interruption.

Network requirements
Receivers receive VOD information through multicast. Receivers of different organizations form stub
•
networks N1 and N2, and Host A and Host C are receivers in N1 and N2 respectively.
Router A in the PIM network connects to N1, and both Router B and Router C connect to another
•
stub network, N2.
• Router A connects to N1 through GigabitEthernet 1/0/1, and to other devices in the PIM network
through GigabitEthernet 0/0/0.
Router B and Router C connect to N2 through their respective GigabitEthernet 1/0/1, and to other
•
devices in the PIM domain through their respective GigabitEthernet 0/0/0.
IGMPv2 is required between Router A and N1. IGMPv2 is also required between the other two
•
routers and N2. Router B acts as the IGMP querier in N2 because it has a lower IP address.
Use the command...
display igmp [ all-instance | vpn-instance
vpn-instance-name ] ssm-mapping group
[ group-address | interface interface-type
interface-number ] [ verbose ] [ | { begin | exclude
| include } regular-expression ]
display igmp ssm-mapping host interface
interface-type interface-number group
group-address source source-address [ | { begin |
exclude | include } regular-expression ]
reset igmp [ all-instance | vpn-instance
vpn-instance-name ] group { all | interface
interface-type interface-number { all |
group-address [ mask { mask | mask-length } ]
[ source-address [ mask { mask |
mask-length } ] ] } }
reset igmp group port-info { all | group-address }
[ vlan vlan-id ]
reset igmp [ all-instance | vpn-instance
vpn-instance-name ] ssm-mapping group { all |
interface interface-type interface-number { all |
group-address [ mask { mask | mask-length } ]
[ source-address [ mask { mask |
mask-length } ] ] } }
