Multihomed Server Configurations Overview
Engine tier servers in a production deployment frequently utilize multihomed server hardware,
having two or more NICs. Multihomed hardware is typically used for one of the following
purposes:
z To provide redundant network connections within the same subnet. Having multiple NICs
ensures that one or more network connections are available to communicate with data tier
servers or the Administration Server, even if a single NIC fails.
z To support SIP communication across two or more different subnets. For example
WebLogic SIP Server may be configured to proxy SIP requests from UAs in one subnet to
UAs in a second subnet, when the UAs cannot directly communicate across subnets.
The configuration requirements and OSI layer information differ depending on the use of
multihomed hardware in your system. When multiple NICs are used to provide redundant
connections within a subnet, servers are generally configured to listen on all available addresses
(IP_ANY) as described in “Multihomed Servers Listening On All Addresses (IP_ANY)” on
page 2-6.
