Question on traffic sourced from a multiple interface LTM
LTM Experts,
I will be adding a second “VIP” type interface as well as corresponding “pool” interface to an existing LTM. My question revolves around where the LTM will send traffic (which interface does it select) when it is sourced from a “pool” member who’s VIP is on this new interface.
Currently my LTM VIP interface is 10.10.10.X and has an internal interface where the pool members reside. I need to add a second interface 10.50.50.x as well as another interface where it’s pool members will reside 10.27.27.X (this LTM will now have 4 interfaces). When this new pool member 10.27.27.X(who’s VIP is on 10.50.50.x) initiates a connection to another host how does the LTM decide which interface to send it on? Will it look in the route table for a route for the network or will it use the interface the VIP is on (10.50.50.X)? I understand for inbound connections the LTM will maintain state and send it on the interface it received it on but I’m wondering how traffic initiated from this new pool (whose default gateway is the LTM) will get forwarded?
Thanks!
