VS and IP resolve(VS) are in 1 BOX

Hi Margvin ,

it's a little bit strange , you need f5 bigip receive traffic on VS_A and forward it to another VS_B on the same box by creating VS_B as a pool attached to VS_A configs. 

this is can be done only using redirect like you said. 
this can't follow the correct traffic flow handling by bigip ( Client >> VS >> Pool_Member ). 

if I missunderstood you , please clarify more even by drawings.
