How ACE classifies the traffic and send it to appropriate Contex

Hi Raj,

ACE decide based on the destination IP.

Remember you should use unique IP and port combination on all the context.

Hope that helps.

Hello Raj,

In addition to what Ajay mentioned, yes each virtual address ( VIP) in combination with the port which you configured( if any) will act as unique identifier for the ACE to handle a specific traffic and finally take the load balance decision it needs or any other action which would be required

Another thing which you can take into consideration from the routing perspective is that you configure on the Admin Context the specific vlans allocated to each contexts based on your requirements so for example: you may allocate this vlan10 for context 1 then vlan 20 for context 2 or all of the vlans for context 3

Going back to your original, yes the ACE works this:

Request ----->VIP--->ACE checks which contexts has the VIP in question---->send request to context--->traffic is load balanced between the servers
