8.2.2 PPPoE Encapsulation
The EMG2926-Q10A supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF
standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem
(DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection
using PPPoE.
For the service provider, PPPoE offers an access and authentication method that works with existing
access control systems (for example Radius).
One of the benefits of PPPoE is the ability to let you access one of multiple network services, a
function known as dynamic service selection. This enables the service provider to easily create and
offer new IP services for individuals.
Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no
specific configuration of the broadband modem at the customer site.
First DNS Server
Second DNS Server
Third DNS Server
Select Obtained From ISP if your ISP dynamically assigns DNS server information
(and the EMG2926-Q10A's WAN IP address). The field to the right displays the (read-
only) DNS server IP address that the ISP assigns.
Select User-Defined if you have the IP address of a DNS server. Enter the DNS
server's IP address in the field to the right.
Select None if you do not want to configure DNS servers. If you do not configure a DNS
server, you must know the IP address of a computer in order to access it.
