A virtual server is a traffic-management object on the BIG-IP system that
is represented by an IP address and a service. Clients on an external network can send
application traffic to a virtual server, which then directs the traffic according to
All virtuals sharing the same router profile will share the same router instance. This means
that they will be able to use connections created by traffic on other virtuals. They will also be
able to route message between each other.
The virtual server configuration contains a destination address and mask which specifies what
IP addresses and port the virtual server will listen for incoming packets. The virtual server
object also contains a source address allowing it to limit packets to those packets that
originate from a range of devices.
The behavior of a virtual server is determined by the set of profiles attached to the virtual
server. In addition, the behavior of a virtual can further be extended by assigning iRules to the
virtual. Furthermore, the transport-config object is used to define the outgoing connection, for
example source address translation, and translation modes of the virtual server. Note, the
virtual server configuration (e.g. pool and persistence profile) used to select a destination is
not used in MRF.
