Can a vserver send traffic to all pool members?

 

 

Can a virtual receive traffic on a single IP/port and then spam that traffic to all members of the pool assigned? I'm thinking specifically UDP traffic and unidirectional.

 

 

Thanks!

  • Unfortunately not, although you can log to multiple sources via UDP so if you're up for some custom server-side code it's possible to send datagrams to multiple places - I've done this in my personal lab and it works.

  • I've never used it, but why doesn't the "Clone Pool (Server)" setting do this? According to the description below, this replicates to a member...but maybe it can be modded to send to all?

     

     

    Clone Pool (Server)

     

     

    Replicates server-side traffic (that is, prior to address translation) to a member of the specified pool. Options are: None, and entries for each already defined pool. The default is None.
  • Clone pool won't help.

     

     

    It is designed to send identical copy of traffic to IDS or equivalent which are listening in promiscuous mode.

     

     

    What the BIGIP will do is to:

     

    1- LB the client connection, Select the destination server.

     

    2- Send it the traffic.

     

    3- it will send the EXACT same packet (same IP than elected server) to the IDS. To do so it will used the MAC address from the server specified in the Clone pool.

     

     

    And it will send the copied packet to only one server in the clone pool.
  • Thanks for your replies. I think we've found a way around this without involving the F5.
