How to send duplicate UDP packet to more than one node

Hi All,

 

I have a scenario where I want to send duplicate udp packet to more than two node. I understand this is possible but can anyone point to the correct documentation or config sample of how it can be done?

 

Thanks,

Crown

    Hi Crown,

     

    You can use "clone" command in iRule.

    There are a number of ways - you can use clone pools to just spray it at layer 2, use the iRule clone command as above, use sideband/HSL if you want to change the content or ultimately use MRF to do complex and really groovy things such as having multiple sessions active etc

    Thanks for your response so far.

     

    The problem I am going to have with spraying is, I have the node several hops away from F5. What will be the best way to address that?

      In which case, an iRule with the clone command would make sense Eg when CLIENT_DATA { clone pool }
