5.
(Optional) Specify the IP inactivity timer.
host1(config-subif)#
ip inactivity-timer 100
6.
(Optional) Specify the source address of traffic that is destined for the primary
IP interface.
host1(config-subif)#
ip source-prefix 192.168.2.1 255.255.255.0
Figure 27 on page 620 shows the interface stack built for this configuration.

Dynamic Subscriber Interface Configuration Example
The procedure in this section shows how to configure dynamic subscriber interfaces
by using the same loopback interface referenced by multiple unnumbered IP
interfaces. Instead of assigning a different IP address to each physical interface, this
example assigns an IP address to a loopback interface (loopback 0). Each physical
interface is then configured as an unnumbered IP interface, referencing the same
loopback interface. This example uses a DHCP local server.
This approach has the following benefits:
■
A loopback interface provides a stable IP address that can minimize the impact
if a physical interface in the network goes down.
■
Unnumbered IP interfaces preserve valuable IP address space.
To configure dynamic subscriber interfaces, perform the following steps:
1.
Enable the DHCP local server for standalone mode.
host1(config)#
service dhcp-local standalone
2.
Access DHCP Local Pool Configuration mode for the local address pool.
host1(config)#
ip dhcp-local pool ispWestford
