Description
If you choose Static IP Address, enter the IP address and subnet
mask or the network bits in the fields provided. For more
information, see
If you choose Dynamic, the router will lease an IP address from a
remote DHCP server. Enter the name of the DHCP server that will
assign addresses.
Choose dynamic DNS if you want to update your DNS servers
automatically whenever the WAN interface IP address changes.
Click the Dynamic DNS button to configure dynamic DNS.
This window lets you enable Point-to-Point-Protocol over Ethernet (PPPoE)
encapsulation. This is necessary if your service provider or network administrator
requires remote routers to communicate using PPPoE.
PPPoE is a protocol used by many asymmetric digital subscriber line (ADSL)
service providers. Ask your service provider if PPPoE is used over your
connection.
If you choose PPPoE encapsulation, Cisco SDM automatically adds a dialer
interface to the configuration, and this is shown in the Summary window.
Field Reference
Table 5-3 describes the fields in this screen.
Description
If your service provider requires that the router use PPPoE, check
this box to enable PPPoE encapsulation. Uncheck this box if your
service provider does not use PPPoE. This check box will not be
available if your router is running a version of Cisco IOS that does
not support PPPoE encapsulation.
