intervlans igmp config

[ocramas]

Hi,

I have a questiong regarding igmp, I have a really easy topology.

Multicast source -------> 3500 switch <----------------> Multicast client

I've my multicast source working and I see the switch interface receiving all the multicast traffic, BUT... it is not passing the multicast to the other port (port 2 - vlan 2), all the traffic is being received by port 1 ( vlan 1)

For some reason, the multicast source is not able to receive the traffic, but it is able to register in the igmp group.

Conf:

ip routing
ip multicast-routing

vlan 1
   name "DEFAULT_VLAN"
   untagged 1,3-48
   ip address 1.1.1.1 255.255.255.0
   no untagged 2
   ip igmp
   exit
vlan 2
   name "Multicast_Client"
   untagged 2
   ip address 2.2.2.2 255.255.255.0
   ip igmp
   exit

show ip igmp:

 VLAN ID : 2
 VLAN Name : VLAN2
 IGMP version : 2
  Querier Address [this switch] : 2.2.2.2
  Querier Port :    
  Querier UpTime : 0h 35m 40s         
  Querier Expiration Time : 0h 1m 7s           

  Active Group Addresses Type       Expires         Ports      Reports Queries
  ---------------------- ---------- --------------- ---------- ------- -------
 224.0.1.1              Filter     0h 4m 19s       2          2360    0    

Any help is really appreciated.

Hi,

You need to configure a layer 3 protocol to route multicast. PIM is an example, it is possible than a L3 licence should needed.

Thanks,

Why the ip multicast-routing is not enough for it?

could you explain..?

Thanks,

Fair enough, I'm reading that and it is quite clear!

Thanks,
