Configuring Dynamic Subscriber Interfaces

You can configure dynamic subscriber interfaces in the following configurations:
The following sections describe how to create each of these basic configurations. In
addition, "Dynamic Subscriber Interface Configuration Example" on page 620, provides
a detailed sample configuration.

Configuring Dynamic Subscriber Interfaces over Ethernet

To configure a dynamic subscriber interface in an IP over Ethernet configuration by
using DHCP events, perform the following steps:
1.
2.
3.
4.
5.
Figure 24 on page 617 shows the interface stack built for this configuration.

Configuring Dynamic Subscriber Interfaces
Use the no version to remove the association between the interface and the
specified IP source address and mask.
See ip source-prefix
IP over Ethernet
IP over VLAN over Ethernet
IP over bridged Ethernet over ATM
GRE tunnels
Configure the DHCP server.
For instructions, see "Configuring the DHCP Local Server" on page 471 .
Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet port.
host1(config)#interface fastEthernet 4/1
Create the primary IP interface by assigning an IP address and mask to the
Ethernet interface (or make it unnumbered).
host1(config-if)#ip address 192.168.2.1 255.255.255.0
Configure the primary IP interface to enable dynamic creation of subscriber
interfaces.
host1(config-if)#ip auto-configure ip-subscriber
(Optional) Specify the source address of traffic that is destined for the primary
IP interface.
host1(config-if)#ip source-prefix 192.168.2.1 255.255.255.0
