Inter-VLAN Multicast IP Routing using a 3560X Switch

[Jeff Harned]

Hello All,

I have a 3560x switch upgraded with the "ip services" license required to do IP multicast routing.  I could use some help with

this since I am having a difficult time on getting things to work correctly. 

I have attached two files; one of the block diagram and one with the configuration of the switch.  I am taking four separte serial input

data streams and converting them each to four separte multicast IP adresses: 239..1.1.3 thru 239.1.1.6.  These four are sent over a single

cable to the switch which I hoped I would be able to route the multicast data to two IP to Serial data conversion units.

These units have LEDs to show data activity but these will just not fire!

Please any help and commnents.

Thanks.

Regards,

Jeff

It does make sense and in fact that is actually what is happening in both receivers!!  They are both receiving the configured multicast addresses of 239.1.1.3

and 239.1.1.5.

Wow, looks like I have routing between VLANs!!

Jon, this has been an important issue with myself for such a long time now and now I should be able to expand from this point using multiple multicast sources.

I really do appreciate you hanging in there with me and teaching me some network workings!!!

Thanks.

Regards,

Jeff
