Configuring IP, MPLS, and PPPoE over Ethernet

To configure IP, MPLS, and PPPoE over an Ethernet interface:

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

   host1(config)#interface fastEthernet 4/0

2. Create an IP interface.

   host1(config-if)#ip address 192.5.127.8 255.255.255.0

3. Create an MPLS interface.

   host1(config-if)#mpls

4. Create a PPPoE interface by specifying PPPoE as the encapsulation method on the interface.

   host1(config-if)#pppoe

5. Create a PPPoE subinterface.

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

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

   host1(config-if)#encapsulation ppp

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 5 through 7 using unique numbering.

Figure 12 illustrates this configuration.

mpls

• Use to enable, disable, or delete MPLS on an interface. MPLS is disabled by default.
• Example

  host1(config)#mpls

• Use the no version to halt MPLS on the interface and delete the MPLS interface configuration.
• See mpls.
