Configuring Pseudowire
Cisco Pseudowire Emulation Edge-to-Edge (PWE3) allows you to transport traffic using traditional
services such as E1/T1 over a packet-based backhaul technology such as MPLS or IP. A pseudowire
(PW) consists of a connection between two provider edge (PE) devices that connects two attachment
circuits (ACs), such as ATM VPIs/VCIs or E1/T1 links.
The following sections describe how to configure pseudowire on the Cisco MWR 2941:
• Understanding Pseudowire, page 23-1
• Configuring Pseudowire, page 23-3
• Configuration Examples for Pseudowire, page 23-18

Understanding Pseudowire
PWs manage encapsulation, timing, order, and other operations in order to make it transparent to users;
the PW tunnel appears as an unshared link or circuit of the emulated service.
There are limitations that impede some applications from utilizing a PW connection. For more
information, see the section describing the PW service.
Cisco supports the following standards-based PWE types:
ATM/TDM ATM/TDMxconnectxconnect
MPLS/IP
