E-series routers currently support dynamic creation of subscriber interfaces with DHCP servers in the following configurations:
For example, Figure 19 shows the interface stacking in an IP over Ethernet dynamic subscriber interface configuration. The illustration indicates which layers in the stack are static and dynamic, and identifies the CLI commands typically used to create the configuration.
Figure 19: IP over Ethernet Dynamic Subscriber Interface Configuration
As shown in Figure 19, issuing the ip auto-configure ip-subscriber command configures the primary IP interface to enable dynamic creation of subscriber interfaces. However, the router does not actually create the dynamic subscriber interface until the DHCP server assigns an IP address to the associated subscriber.
To configure each supported configuration, see Configuring Dynamic Subscriber Interfaces.
