Configuring a PPPoE Subinterface for a LAG Bundle

To configure a PPPoE subinterface for the LAG bundle, perform the following steps:

1. Specify PPPoE as the encapsulation method.

   host1(config-if)#encapsulation pppoe

2. Specify the PPPoE subinterface for the LAG bundle in either of the following ways:
   • Use the interface lag command to add a unique subinterface number to the LAG bundle name.

     host1(config)#interface lag bundleBoston.2

   • Use the pppoe subinterface lag command to add a unique subinterface number to the LAG bundle name.

     host1(config)#pppoe subinterface lag bundleBoston.2

3. Specify PPP as the encapsulation method on the PPPoE subinterface.

   host1(config-if)#encapsulation ppp

4. Assign an IP address and mask.

   host1(config-if)#ip address 192.168.1.2 255.255.0.0

You can also configure a PPPoE subinterface over a VLAN subinterface over a LAG bundle. For an example of this configuration, see Example: Configuring a PPPoE Subinterface over a VLAN for a LAG Bundle.
