Multicasting between vlan

[kkpc]

Hi,

I need help for configuration cisco catalist 4500x and catalyst 3750 protokol multicast.

swtitch 4500x is set to layer3:

ip multicast-routing

interface vlan 200

ip pim sparse-mode

interface vlan 203

ip pim sparse-mode

ip pim rp-address (ip 4500x)

swtitch 3750:

ip multicast-routing

interface vlan 200

ip pim sparse-mode

interface vlan 203

ip pim sparse-mode

ip pim rp-address (ip 4500x)

server is vlan 200

camers is vlan 203

Multicating between vlan200 and 203 not routing, why ?

Working multicasting inside vlan but between vlans is not working.

Thanks for help.

I heve a question,
In the case of multicasts on one switch we configure routing-multicast ?,
Do you need on everyone ?
Only igmp on the others ?

Thx,

@kkpc Hello

Could you share below configuration:

ON 4500X

show running-config 

ON 3750

show running-config

?

Because in your topology you told to us that just 4500X is configured as L3 device, in this case, you wont neeed a interface vlan 200 and 203 on others switch and wont need "ip pim sparse-mode" under interface on them.

igmp is default enabled on cisco devices.

ok, good. Connection between switch, could you share configuration under interface?

[kkpc]

Communication between switches is possible over a LAN. I will remove PIM from the other switches tomorrow and see if it works.

Thx for help.

I removed PIM from the other switches and is working.

Nice guy... thank you for your feedback :)
