Configuring PPPoE Without VLANs

To configure PPPoE over an Ethernet interface without VLANs:

1. Specify a Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface.

   host1(config)#interface fastEthernet 4/1

2. Specify PPPoE as the encapsulation method on the interface.

   host1(config-if)#pppoe

3. Create a PPPoE subinterface.

   host1(config-if)#pppoe subinterface fastEthernet 4/1.1

4. Specify PPP as the encapsulation method on the interface.

   host1(config-subif)#encapsulation ppp

5. (Optional) Configure an access concentrator (AC) name on the PPPoE interface.

   host1(config-subif)#pppoe acname CYM9876

6. (Optional) Set up the router to prevent a client from establishing more than one session using the same MAC address.

   host1(config-subif)#pppoe duplicate-protection

7. Assign an IP address and mask.

   host1(config-if)#ip address 192.6.129.5 255.255.255.0

8. (Optional) Configure additional PPPoE subinterfaces by completing Steps 3 through 7 using unique numbering.

Figure 35 illustrates the interface stack for this configuration.

encapsulation ppp

• Use to specify PPP as the encapsulation method for the interface.
• Example

  host1(config-if)#encapsulation ppp

• Use the no version to disable PPP on an interface.
• See encapsulation ppp.

interface fastEthernet

• Use to select a Fast Ethernet interface.
• For more information, see chapter Configuring Ethernet Interfaces in JUNOSe Physical Layer Configuration Guide.
• Example

  host1(config)#interface fastEthernet 1/0

• Use the no version to remove IP from an interface or subinterface. You must issue the no version from the highest level down; you cannot remove an interface or subinterface if the one above it still exists.
• See interface fastEthernet.

interface gigabitEthernet

interface tenGigabitEthernet

• Use to select a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface.
• To specify a Gigabit Ethernet interface for ERX-7xx models, ERX-14xx models, and ERX-310 routers, use the slot/port[.subinterface ] format.
• To specify a Gigabit Ethernet interface or 10-Gigabit Ethernet interface for E120 and E320 routers, use the slot/adapter/port[.subinterface ] format.
• For more information, see chapter Configuring Ethernet Interfaces in JUNOSe Physical Layer Configuration Guide.
• Examples

  host1(config)#interface gigabitEthernet 1/0

  host1(config)#interface gigabitEthernet 4/0/1 6.0.0FRS

  host1(config)#interface tenGigabitEthernet 4/0/1

• Use the no version to remove IP from an interface. You must issue the no version from the highest level down; you cannot remove an interface or subinterface if the one above it still exists.
• See interface gigabitEthernet.
• See interface tenGigabitEthernet.

ip address

• Use to assign an IP address and subnet mask to an interface or subinterface.
• Example

  host1(config-if)#ip address 192.1.1.1 255.255.255.0

• Use the no version to remove an IP address or disable IP processing.
• See ip address.

pppoe

• Use to specify PPPoE as the encapsulation method for the interface.
• This command creates a PPPoE major interface.
• Example

  host1(config-if)#pppoe

• Use the no version to remove the PPPoE major interface.
• See pppoe.

pppoe acName

• Use to configure an access concentrator (AC) name on the PPPoE interface. When the AC (the server) receives a PPPoE Active Discovery Initiation (PADI) packet that it can serve, it replies by sending a PPPoE Active Discovery Offer (PADO) packet. The PADO packet contains the AC name configured using this command.
• If the AC name is not configured, the router name is used.
• The AC name can be a maximum of 64 characters.
• Example

  host1(config-subif)#pppoe acName CYM9876

• Use theno version to remove the AC name.
• See pppoe acName.

pppoe duplicate-protection

• Use to prevent a client from establishing more than one session using the same MAC address.
• This feature is disabled by default.
• Example

  host1(config-subif)#pppoe duplicate-protection

• Use the no version to disable duplicate protection.
• See pppoe duplicate-protection.

pppoe subinterface fastEthernet

• Use to create a PPPoE subinterface on a Fast Ethernet module.
• On ERX-7xx models, ERX-14xx models, and the ERX-310 router, use the slot/port/pppoeSubinterface format.
• Example

  host1(config)#pppoe subinterface fastEthernet 4/1.1

• Use the no version to remove the PPPoE subinterface.
• See pppoe subinterface.
