How do you configure the router to listen for IGMP join requests
on an interface if it's not PIM enabled?
Rack1R1(config)#ip multicast-routing
Rack1R1(config)#do sh ip igmp int fa0/0
FastEthernet0/0 is up, line protocol is up
Internet address is 164.1.18.1/24
IGMP is disabled on interface <-----------------------
Multicast routing is disabled on interface <-----------
Multicast TTL threshold is 0
No multicast groups joined by this system
Rack1R1(config)#int fa0/0
Rack1R1(config-if)#ip pim dense-mode
Rack1R1(config-if)#do sh ip igmp int fa0/0
FastEthernet0/0 is up, line protocol is up
Internet address is 164.1.18.1/24
IGMP is enabled on interface <------------------------
Current IGMP host version is 2
Current IGMP router version is 2
IGMP query interval is 60 seconds
IGMP querier timeout is 120 seconds
IGMP max query response time is 10 seconds
Last member query count is 2
Last member query response interval is 1000 ms
Inbound IGMP access group is not set
IGMP activity: 1 joins, 0 leaves
Multicast routing is enabled on interface <------------
