Multicast Support for 6509

Hi,

I have two 6509 Switches at my Core layer.

Since this new devices our engineers are unable to run the ghost images for their desktop creation.

I beleive the necessary multicast used by ghost may not be supported.

kindly give me your suggestions on this.

Rgds,

Amol

Re: Multicast Support for 6509

The most common issue with Ghost in a multicast network is that the TTL is usually set to 1 by default. It will therefore not traverse a layer 3 device by default. Try raising the value of the TTL on the Ghost server.

One more thing. Make sure that multicast is configured on the 6500.

Hope this helps,

Re: Multicast Support for 6509

Can you please provide your configuration for both core switches. I have had an issue with Ghost running on my backbone cores as well. The multicast traffic was not going across the trunk to the other switch. The Ghost server was on one switch and the clients were on the other switch. I had to place the command ip igmp snooping mrouter interface port-channel1 under the interface vlan associated with my ghost clinets. This command points the multicast traffic along the port channel to the other switch. Also I had to enable multicast routing and enable igmp snooping on the interfaces along with ip pim-sparse mode... Check to see if you need any of these commands to assist you...
