DETAILED STEPS

Command or Action

Purpose

Step 1

enable

Changes the privilege level for the corresponding CLI
session.

Step 2

configure terminal

Example:

Router# configure terminal

Enters global configuration mode.

Step 3

pseudowire-class

pw-class-name

Example:

Router(config)# pseudowire-class pw-ip-ether

Specifies the name of a Layer 2 pseudowire class and
enters pseudowire class configuration mode.

Step 4

encapsulation mpls

Example:

Router(config-pw)# encapsulation mpls

Uses MPLS as the tunneling method to encapsulate data
in the pseudowire.

Step 5

interworking ip

Example:

Router(config-pw)# interworking ip

Enables the L2VPN Interworking feature, and causes IP
packets to be extracted from the attachment circuit and
sent over the pseudowire. Attachment circuit frames that
do not contain IPv4 packets are dropped.

Step 6

interface GigabitEthernet

slot | subslot | port

Example:

Router(config)# interface GigabitEthernet0/0/0.3

Specifies the Gigabit Ethernet interface, and enters
interface configuration mode.

Step 7

encapsulation dot1Q

vlan-id

Example:

Router(config-if)# encapsulation dot1Q 3

Enables IEEE 802.1Q encapsulation of traffic on a
specified subinterface in a VLAN.

Step 8

xconnect

peer-ip-address vc-id pseudowire-class

pw-class-name

Example:

Router(config-if)# xconnect 16.16.16.16 100

pseudowire-class pw-ip-ether

Binds an attachment circuit to a pseudowire to configure
an AToM static pseudowire, specifies MPLS as the
tunneling method, and enters xconnect configuration
mode.
