Example: Configuring A Pppoe Subinterface For A Lag Bundle - Juniper JUNOSE 11.1.X - LINK LAYER CONFIGURATION 4-7-2010 Configuration Manual

JUNOSe 11.1.x Link Layer Configuration Guide
The following commands create a virtual router, add the Ethernet physical interfaces
to a LAG bundle named bundleBoston, and assign an IP address and mask to the
bundle.

Example: Configuring a PPPoE Subinterface for a LAG Bundle

The following example displays LACP configuration for two Fast Ethernet interfaces
in slot 4. The interfaces are enabled for passive LACP. The speed and duplex
characteristics are the same for both interfaces.
The following commands add the Ethernet physical interfaces to a LAG bundle named
chicago.
The following commands configure a PPPoE subinterface for the LAG bundle named
chicago. In the LAG interface identification command (interface lag chicago.1), the
number 1 represents the subinterface number for the PPPoE subinterface.
As an alternative to using the command interface lag chicago.1 to configure the
PPPoE subinterface in this example, you can also use the command pppoe
subinterface lag chicago.1 to achieve the same result. For more information, see
"pppoe subinterface lag" on page 207.
