You can use the VPN-Interface-PPP-Ethernet template for vEdge Cloud and vEdge router devices.

Point-to-Point Protocol (PPP) is a data link protocol used to establish a direct connection between two nodes. PPP properties are associated with a PPPoE-enabled interface on vEdge routers to connect multiple users over an Ethernet link.

To configure PPPoE on vEdge routers using vManage templates:

Create a VPN-Interface-PPP-Ethernet feature template to configure a PPPoE-enabled interface as described in this article.
Create a VPN-Interface-PPP feature template to configure PPP parameters for the PPP virtual interface. See the Configuration ► Templates ► VPN-Interface-PPP help topic
Optionally, create a VPN feature template to modify the default configuration of VPN 0. See the Configuration ► Templates ► VPN help topic.
Create a device template that incorporates the VPN-Interface-PPP, VPN-Interface-PPP-Ethernet, and VPN feature templates. See the Configuration ► Templates help topic.

Some versions of the VPN-Interface-PPP-Ethernet feature template include sections for VRRP and ARP. You cannot configure VRRP or ARP on PPPoE-enabled interfaces, so do not use these sections of the template.

Navigate to the Template Screen

In vManage NMS, select the Configuration ► Templates screen.
From the Templates title bar, select Feature.
Click Add Template.
In the left pane, select one or more devices. The right pane displays the available templates for the selected devices.
Select the VPN-interface-PPP-Ethernet template.

The right pane displays the VPN-Interface-PPP-Ethernet template form.

The top of the form contains fields for naming the template.
The bottom contains fields for defining parameters applicable to that template.
A drop-down menu to the left of each parameter field defines the scope of the parameter. When you first open a feature template form, for each parameter that has a default value, the scope is set to Default. To edit a parameter field, change the scope to Global or Device Specific. Note that if a parameter's scope is Device Specific, you cannot enter a value for it in the feature template. Instead, you enter a value when you attach the template to a device.
A plus sign (+) is displayed to the right when you can add multiple entries for the same parameter.

Minimum PPPoE-Enabled Interface Configuration

The following parameters are required (unless otherwise indicated) to create a PPPoE-enabled interface on a vEdge router:

Step	Parameter Field	Procedure
1.	Template Name	Enter a name for the template. It can be up to 128 characters and can contain only alphanumeric characters.
2.	Description (Template)	Enter a description for the template. It can be up to 2048 characters and can contain only alphanumeric characters.
3.	Shutdown	Click No to enable the PPPoE-enabled interface.
4.	Interface name	Enter the name of the physical interface in VPN 0 to associate with the PPP interface.
5.	Description (optional)	Enter a description of the PPPoE-enabled interface.
6.	IP configuration	Select Dynamic to set the interface as a DHCP client, to allow the interface to receive its IP address from a DHCP server. If you select Dynamic, you can set the DHCP distance to specify the administrative distance of routes learned from a DHCP server. The default DHCP distance is 1.
7.	IPv4 address	Enter the IPv4 address of the interface if the interface is not receiving its IP address from a DHCP server.
8.	DHCP helper (optional)	Enter up to four IP addresses for DHCP servers in the network, separated by commas, to have the interface be a DHCP helper. A DHCP helper interface forwards BOOTP (Broadcast) DHCP requests that it receives from the specified DHCP servers.
9.	Save	Click Save to save the feature template.

CLI equivalent:

vpn 0
  interface pppnumber
    description text
    dhcp-helper ip-address
    (ip address address/subnet | ip-dhcp-client [dhcp-distance number])
    pppoe-client ppp-interface pppnumber
    [no] shutdown

Apply Access Lists

To configure a shaping rate to a PPPoE-enabled interface and to apply a QoS map, a rewrite rule, access lists, and policers to the interface, select the ACL tab:

Parameter Name	Description
Shaping rate	Configure the aggregate traffic transmission rate on the interface to be less than line rate, in kilobits per second (kbps).
QoS map	Specify the name of the QoS map to apply to packets being transmitted out the interface.
Rewrite rule	Click On, and specify the name of the rewrite rule to apply on the interface.
Ingress ACL	Click On, and specify the name of the access list to apply to packets being received on the interface.
Egress ACL	Click On, and specify the name of the access list to apply to packets being transmitted on the interface.
Ingress policer	Click O,n and specify the name of the policer to apply to packets being received on the interface.
Egress policer	Click On, and specify the name of the policer to apply to packets being transmitted on the interface.

CLI equivalent:

vpn 0
  interface pppnumber
    access-list acl-list (in | out) 
    policer policer-name (in |out)
    qos-map name
    rewrite-rule name
    shaping-rate name

Configure Other Interface Properties

To configure other interface properties, select the Advanced tab:

Parameter Name	Description
Duplex	Choose full or half to specify whether the interface runs in full-duplex or half-duplex mode. Default: full
MAC Address	Specify a MAC address to associate with the interface, in colon-separated hexadecimal notation.
IP MTU	Specify the maximum MTU size of packets on the interface. Range: 576 through 1804 Default: 1500 bytes
PMTU discovery	Click On to enable path MTU discovery on the interface. PMTU determines the largest MTU size that the interface supports so that packet fragmentation does not occur.
Flow control	Select a setting for bidirectional flow control, which is a mechanism for temporarily stopping the transmission of data on the interface. Values: autonet, both, egress, ingress, none Default: autoneg
TCP MSS	Specify the maximum segment size (MSS) of TPC SYN packets passing through the vEdge router. By default, the MSS is dynamically adjusted based on the interface or tunnel MTU such that TCP SYN packets are never fragmented. Range: 552 to 1460 bytes Default: None
Speed	Specify the speed of the interface, for use when the remote end of the connection does not support autonegotiation. Values: 10, 100, or 1000 Mbps Default: Autonegotiate (10/100/1000 Mbps)
Static ingress QoS	Specify a queue number to use for incoming traffic. Range: 0 through 7
ARP timeout	Specify how long it takes for a dynamically learned ARP entry to time out. Range: 0 through 2678400 seconds (744 hours) Default: 1200 seconds (20 minutes)
Autonegotiate	Click Off to turn off autonegotiation. By default, an interface runs in autonegotiation mode.
TLOC Extension	Enter the name of a physical interface on the same router that connects to the WAN transport. This configuration then binds this service-side interface to the WAN transport. A second vEdge router at the same site that itself has no direct connection to the WAN (generally because the site has only a single WAN connection) and that connects to this service-side interface is then provided with a connection to the WAN.
