IBM AS/400E Example: The Multihoming function

Example: The Multihoming function
Assume AS/400 systems SYSNAM02 and SYSNAM03 are connected with a public
or private X.25 network. The Internet address of this network is 9.4.73.64.
In this example, the AS/400 system SYSNAM03 connects with a service provider by
using TCP/IP and the same X.25 network attachment (Figure61). The Internet
address assigned by the service provider for the AS/400 system is 223.1.1.17.
The multihoming function supports multiple networks with the same adapter.AS/400
system SYSNAM03 must handle two different Internet addresses on the same
attachment. Todo this, an additional TCP/IP interface needed to be specified
(Figure 62 on page 83).
