Route 95% of traffic to 1 pool and 5% of traffic to another pool.

I'm looking at the best way to route 95% of our traffic to one pool and the remaining 5% to a different pool. Has anyone successfully done this before?

Sounds like Ratio load balancing.
But that's at the pool member level, not sure if you can do it at the pool level.
I've only ever done pool to pool stuff for failover.

You can do this via an iRule on a random basis.

when CLIENT_ACCEPTED {
  if { [expr { rand() * 100 }] > 95 } {
    pool <other pool>
  }
}

Hi,

1. In this case you have BIG-IP DNS, You can specific load balance method ratio for distribute traffic 95% to PoolA and 5% to Pool B

2. If you don't have BIG-IP DNS, So i think you have to create irules for thie scenario
