Configuring Dynamic Subscriber Interfaces over Bridged Ethernet

606
To configure a dynamic subscriber interface in an IP over bridged Ethernet over ATM
configuration by using DHCP events, perform the following steps:
Configure DHCP server.
1.
For instructions, see "Configuring the DHCP Local Server" on page 465 .
Create an ATM major interface.
2.
host1(config)#interface atm 3/3
Create an ATM 1483 subinterface.
3.
host1(config-if)#interface atm 3/3.1
Configure an associated PVC for the ATM 1483 subinterface by specifying the VCD,
4.
the VPI, the VCI, and the encapsulation type.
host1(config-subif)#atm pvc 10 100 22 aal5snap
Specify bridged Ethernet as the encapsulation method on the ATM 1483 subinterface.
5.
host1(config-subif)#encapsulation bridge1483
Create the primary IP interface by assigning an IP address and mask to the bridged
6.
Ethernet interface (or make it unnumbered).
host1(config-subif)#ip address 192.168.2.20 255.255.255.0
Configure the primary IP interface to enable dynamic creation of subscriber interfaces.
7.
host1(config-subif)#ip auto-configure ip-subscriber
(Optional) Specify the source address of traffic that is destined for the primary IP
8.
interface.
host1(config-subif)#ip source-prefix 192.168.2.20 255.255.255.0
Figure 26 on page 607 shows the interface stack built for this configuration.
