NimbostratusRouting LTM data traffic among 2 interfaces
Hi Experts
If one interface (1.1) of LTM is passing data traffic , is it possible that data traffic from another interface (1.2) can send the traffic to 1.1 ? If yes please let me know how the routing will happen among 2 interfaces ? Also is it possible that the VLAN2 of one interface (1.1) can send the traffic to VLAN3 of same interface ?
If it is possible do we need to change the VIP Type to 'Forwarding" or need to keep it "Standard" ?

Ankur, In your scenario, is interface 1.1 tied to vlan1 and interface 1.2 tied to vlan2 ?
By default, the BIG-IP won't route between subnets unless there is a virtual server directing it to do so. If you had a scenario like this: vlan1 (1.1) - self 10.10.10.0/24 vlan2 (1.2) - self 20.20.20.0/24 and you wanted traffic to go from vlan1 to vlan2, then you would create a forwarding virtual server where the destination is the subnet tied to vlan2.
Virtual Server: Destination 20.20.20.0/24 type forwarding.
That would allow traffic destined for 20.20.20.0/24 to follow the routing table.
If you wanted to limit it to only traffic FROM vlan1 can go to vlan2, then in that virtual server, enable it only on vlan1.
