Which interfaces of the AR router support PPPoE dialup

31

1. A VT interface must be bound to an interface so that the PPPoE server can be implemented.
The PPPoE server can be configured on a physical Ethernet interface, a PON interface, a VLANIF interface, or a virtual Ethernet interface.

2. The dialer interface must be bound to an interface so that the PPPoE client can be implemented.
The PPPoE client can be configured on a physical Ethernet interface, a PON interface, or a virtual Ethernet interface.

The physical Ethernet interfaces refer to WAN-side Ethernet interfaces. LAN-side Ethernet interfaces do not support PPPoE.

Does the AR router support PPPoE automatic re-dialup
When the AR router functions as the PPPoE or PPPoEoA client, it continuously sends connection requests to the PPPoE or PPPoEoA server. When the maximum number of connection attempts is reached during the quiet period, the PPPoE or PPPoEoA server does not receive requests from the client. The PPPoE or PPPoEoA server receives connection requests only after the quiet period is exceeded. During the quiet period, the client repeatedly sends connection requests to the PPPoE or PPPoEoA server, wasting resources. The quiet period and retransmission count during the silent period can be configured to solve this problem. When the retransmission count is exceeded during the quiet period, the client stops sending connection requests.

Does VLANIF interfaces of the AR router support the PPPoE client
The PPPoE client cannot be configured on a VLANIF interface, but the PPPoE server can be configured on the VLANIF interface.
