What is IPv4 PPPoE?
Point To Point Protocol (PPP) and Point To Point Protocol over Ethernet (PPPoE) are network protocols that allow data communication between two network entities or points. Both protocols exist at the network access layer (also known as the data link layer) that supports network layer protocols including IPv4 and IPv6.
Which packets are used for PPPoE negotiation?
PPPoE Negotiation
- The user broadcasts a PPPoE Active Discovery Initiation (PADI) packet carrying the service that it is requesting.
- After receiving the PADI packet, all access concentrators (ACs) on the Ethernet network compare the requested service against the services they can offer.
What is PPPoE connection type?
Point-to-Point Protocol over Ethernet (PPPoE) and Point-to-Point Protocol over Asynchronous Transfer Mode (PPPoA) are Internet connection types mainly used by Digital Subscriber Line (DSL) ISPs to establish Internet connection for end-users. These are used mainly for DSL and Asymmetric DSL (ADSL) services.
Does PPPoE use DHCP?
DHCP is a protocol for obtaining IP addresses while PPPOE is a common method of connecting to an ISP. DHCP is very popular and is widely used while PPPOE is slowly falling out of favor. You would need to have a username and password with PPPOE while the configuration of DHCP is automatic.
Which is best PPPoE and PPTP?
Both PPPoE and PPtP can both be encrypted. Encryption will reduce the bandwidth. The advantage of PPPoE is that you only need supply the user with a username/password combination. PPtP requires username password and endpoint IP address.
Is PPPoE same as PPtP?
PPPoE allows Internet Service Providers (ISPs) to manage Internet access to accounts through the use of usernames and passwords and hence offers better security and control for the home user. The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks.
What is the process of PPPoE Session Initiation?
PPPoE session initiation involves the identification of the Media Access Control (MAC) address of the remote device. This process, also known as PPPoE discovery, involves the following steps: Initiation – The client software sends a PPPoE Active Discovery Initiation (PADI) packet to the server to intitiate the session.
How can I tell which phase of PPPoE is active?
You can tell which phase is active by the type field of the Ethernet frame. Here you’ll either find 0x8863 for discovery or 0x8864 for session. The type field is followed by the PPPoE frame, embedded in the data field of the Ethernet frame.
Can a service provider use both PPP and PPPoE?
Service providers can use the same authentication server for both PPP and PPPoE sessions, resulting in a cost savings. PPPoE uses standard methods of encryption, authentication, and compression specified by PPP. PPPoE is configured as a point to point connection between two Ethernet ports.
What is the IETF specification for PPP and PPPoE?
The IETF specification for PPPoE is RFC 2516. PPPoE expands the original capability of PPP by allowing a virtual point to point connection over a multipoint Ethernet network architecture.
