Configuring Higher-Level Protocols over S-VLANs

The procedures for configuring IP, PPPoE, and MPLS protocols over S-VLANs on bridged Ethernet interfaces are identical to the procedures for configuring these protocols over VLANs on bridged Ethernet interfaces.

This section provides an example for configuring PPPoE interfaces over S-VLAN subinterfaces configured on bridged Ethernet. For descriptions of the commands used in this procedure, see Configuring Higher-Level Protocols over VLANs.

To configure PPPoE over S-VLAN over a bridged Ethernet interface:

  1. Follow the steps in Configuring S-VLAN Subinterfaces over Bridged Ethernet to configure the S-VLAN subinterface.
  2. Create a PPPoE major interface on the S-VLAN subinterface.
    host1(config-subif)#pppoe
  3. Exit the subinterface context.
    host1(config-subif)#exit
  4. Create a PPPoE subinterface by adding a subinterface number to the interface identification command.
    host1(config)#pppoe subinterface atm 3/1.1.1.1
  5. Specify PPP as the encapsulation method on the interface.
    host1(config-subif)#encapsulation ppp
  6. Assign an IP address and mask to the interface.
    host1(config-subif)#ip address 10.1.2.3 255.255.255.255
