We are trying to set up basic multicasting (Single VLAN no multicast across subnets) for the purpose of workstation imaging (Apple Software Restore, Ghost, Zenworks, etc.). We are able to multicast, but increasing the multicast rate to an acceptable level floods the network. It appears that the multicast packets are being replicated out to all switch ports on the vlan.
Thank you for your response and pointing me to that doc. I seem to have things working now, but am still confused about something.
I have attached a text document with detailed network layout, configs, and SHOW command results.
I enabled PIM sparse mode on VLAN1 of the 4506. I then set up a test environment using Cisco's MRM to try things out. The output seemed to indicate 100% packet loss and that multicast was still not set up properly (see stats in attachment).
After playing with different settings this morning and not getting the MRM test environment to do anything but show 100% packet loss I decided to try a live multicast for the heck of it. The multicast session worked very well (24 workstations attached to CHS_CISCO_MACLAB_01 and a source server on GigabitEthernet 0/3 of CHS_CISCO_SERVER_01) without forwarding packets to anything but the necessary ports on the 4506.
So, some change I made seems to have worked. But, why is the MRM output showing a problem? Am I still missing something?
