Hi all,
I am trying to configure ipv6 multicast routing on a 3750x catalyst switch. But i am not able to find the commands.
I have a 7604 switch in which I was able to configure ipv6 multicast routing with ipv6 multicast-routing command but i am not able find the same commands in 3750x switch.
I searched on the net and found out that multicast routing is only supported in IP services package.
Current running software is
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 54 WS-C3750X-48P 12.2(58)SE2 C3750E-UNIVERSALK9-M
I am not sure whether this is a base package or services package.
Could someone help me figure out whether i could configure ipv6 multicast routing on this SW or an upgrade to services package is needed.
Thanks.

Hi,
To run multicast, you need IP services license installed. To see what license you have try "sh license" and "sh ver"

Hi Georg,
Thanks for the reply.
Are there any other commands to configure multicast routing? Or should i upgrade IOS?
My requiremets are fairly simple. I have one 3750x which acts as an L3 switch which does the switching/routing between vlans.
I have two hosts , one is in vlan X (server) and other one is in vlan Y (client). Client joins the multicast group by sending MLDv2 messages. Server sends data to that multicast group. BTW this is source specific multicast (SSM).
I was able to make this work in 7604 switch by enabling MLD version 2/ MLD snooping and IPv6 multicast routing.
Are there any commands to make the above configuration work in this IOS or should I upgrade my IOS?

Hello,
IPv6 Multicast Routing is supported only on the IP Services image.
'show license'
should show you which feature set you have installed.

Hello,
Thanks for the answer. Looks like switch has ip services pacage only, but still i am not able to configure ipv6 multicast routing.

Hi,
That is correct, you have IP services license installed.
Try this config
Also, here is the link to the config guide for more info:

Hi,
I already configured sdm dual stack settings and unicast- routing. I am able to configure ipv4 multicast routing also, problem is only with ipv6 multicast routing.
