Is PPPoE better than DHCP?
Conclusion. There is not better than the other, they serve two entirely different functions, with zero overlap. Both PPPoE and DHCP are critical in connecting to the network, which works to acquire IP address. What distinguishes PPPoE vs DHCP is the methods to obtain IP.

How do I configure my router for remote access?
All you need to do is type the router IP or default gateway address in the web browser. Next, enter your username and password. Now, once you are in the router's web portal, look for the Remote Management option. Some routers called it Remote Access and it's usually found under Advanced Settings.
Which protocol should be used to manage a switch remotely?
Secure Shell (SSH) is a protocol that provides a secure (encrypted) management connection to a remote device.
Is Vty Telnet or SSH?
An efficient way to manage remote devices is to use VTY access, which is CLI-based remote access using Telnet or SSH. Telnet uses TCP port number 23. Telnet is a simple protocol and does not encrypt communications.
What is a PPPoE connection?
Point-to-Point Protocol over Ethernet (PPPoE) combines PPP, which typically runs over broadband connections, with the Ethernet link-layer protocol that allows users to connect to a network of hosts over a bridge or access concentrator.
What is PPPoE dialer interface?
PPPoE. The PPPoE Client feature on the router provides PPPoE client support on Ethernet interfaces. A dialer interface must be used for cloning virtual access. Multiple PPPoE client sessions can be configured on an Ethernet interface, but each session must use a separate dialer interface and a separate dialer pool.
What is the PPPoE username and password?
Your username is displayed at the top of the panel, below your package. To get your password, click on the 'Access Details' button.
What is a PPPoE connection?
Point-to-Point Protocol over Ethernet (PPPoE) combines PPP, which typically runs over broadband connections, with the Ethernet link-layer protocol that allows users to connect to a network of hosts over a bridge or access concentrator.
How does PPPoE work?
PPPoE is configured as a point to point connection between two Ethernet ports. As a tunneling protocol, PPPoE is used as an effective foundation for the transport of IP packets at the network layer. IP is overlaid over a PPP connection and uses PPP as a virtual dial-up connection between points on the network.
What is PPPoE dialer interface?
PPPoE. The PPPoE Client feature on the router provides PPPoE client support on Ethernet interfaces. A dialer interface must be used for cloning virtual access. Multiple PPPoE client sessions can be configured on an Ethernet interface, but each session must use a separate dialer interface and a separate dialer pool.
Does PPPoE work in Packet Tracer?
Point-to-Point Protocol over Ethernet (PPPoE) is a network protocol which encapsulates PPP frames inside Ethernet. PPPoE is a Client/Server protocol and it allows divided multiple clients to use a single server connection.

Prerequisites for the PPPoE Agent Remote-ID and DSL Line Characteristics Enhancement
It is recommended that you be familiar with the following documents before configuring this feature:
Information About the PPPoE Agent Remote-ID and DSL Line Characteristics Enhancement
Broadband DSLAM and Broadband Remote Access Server (BRAS) vendors need to provide Fast or Gigabit Ethernet-based networks as an alternative to an ATM access network, with a DSLAM bridging the ATM-DSL local loop to the Fast or Gigabit Ethernet-based broadband access network and allowing Fast or Gigabit Ethernet-based connectivity to the BRAS.
How to Configure the PPPoE Agent Remote-ID and DSL Line Characteristics Enhancement
This task describes how to configure the PPPoE Agent Remote-ID and DSL Line Characteristics Enhancement feature. When this feature is configured, BRAS will process the incoming PADR frames and send the Remote-ID field of the incoming tag to the RADIUS server as a VSA.

What is the purpose of a BNG router?
The goal of the BNG architecture is to enable the BNG router to interact with peripheral devices (like CPE) and servers (like AAA and DHCP), in order to provide broadband connectivity to subscribers and manage subscriber sessions. The basic BNG architecture is shown in this figure.
Does Cisco IOS XR 64 bit use BNG?
Unlike the Cisco IOS XR 32-bit BNG, the Cisco IOS XR 64-bit BNG does not use the BNG pie, asr9k-bng-px.pie . Instead, it uses the mini.iso or the full.iso image that combines all service packages including the BNG service package for the Cisco IOS XR 64-bit ASR9000 Series Router. Also, a .rpm package is available separately for the BNG services.
Can BNG connect to more than one DHCP server?
BNG can connect to more than one DHCP server to have fail over redundancy in the addressing process. The DHCP server contains an IP address pool, from which it allocates addresses to the CPE. During the interaction between BNG and the DHCP server, BNG acts as a DHCP relay or DHCP proxy.
What is BRAS in ISP?
A broadband remote access server ( BRAS, B-RAS or BBRAS) routes traffic to and from broadband remote access devices such as digital subscriber line access multiplexers (DSLAM) on an Internet service provider 's (ISP) network. BRAS can also be referred to as a broadband network gateway or border network gateway ( BNG ).
What is a BNG gateway?
BRAS can also be referred to as a broadband network gateway or border network gateway ( BNG ). The BRAS sits at the edge of an ISP's core network, and aggregates user sessions from the access network. It is at the BRAS that an ISP can inject policy management and IP quality of service (QoS). The specific tasks include:
