Create multiple copies of UDP packets

Hello,

 

 

Is it possible for an LTM to receive a UDP packet and then send it to multiple destinations?

 

 

We have a one-way traffic flow of UDP packets through the bigip, and would like it to take each packet and create multiple copies destined to different nodes.

 

 

Thanks,

    Hi Dan,

     

     

    Unfortunately, I think the answer is no:

    Not really. You can create a clone pool and send it to at least one more member, but that is about it.

    Hi Dan,

     

    Sounds similiar to Multicasting used in streaming media. Will the nodes react to the packets where it will want to talk back to the source?

    Thanks all for the answers, it doesn't sound like it is possible which is the conclusion I was coming to when trying to attempt an iRule for this.

     

     

    Needed some type of 'release packet/data' command for this to work, ie:

     

    when CLIENT_DATA {

     

    node 1.1.1.1

     

    'release data'

     

    node 1.1.1.2

     

    'release data'

     

    node 1.1.1.3

     

    }

     

     

    But that's ok, maybe in some future version...
