I'm doing some labs using 3750's, for a reason I cannot figure out,
these will not respond to pings if on physical port (no switchport)
you configure `ip igmp join-group X` _unless_ you also enable PIM on the
on the interface and enable `ip multicast-routing distributed`.
Does anyone know why this is?
Wont work:
interface FastEthernet1/0/3
no switchport
ip address 12.2.40.5 255.255.255.0
ip igmp join-group 225.1.1.1
no ip mroute-cache
Will work:
ip multicast-routing distributed
!
interface FastEthernet1/0/3
no switchport
ip pim dense-mode (or sparse etc)
ip address 12.2.40.5 255.255.255.0
ip igmp join-group 225.1.1.1
no ip mroute-cache
They are all WS-C3750-24TS running 12.2(25)SEE C3750-ADVIPSERVICESK.
