Chapter 21 Configuring Pseudowire

Configuring Pseudowire

 

Command

Purpose

Step 1

 

 

enable

Enables privileged EXEC mode.

 

 

Enter your password if prompted.

 

Example:

 

 

Router> enable

 

Step 2

 

 

configure terminal

Enters global configuration mode.

 

Example:

 

 

Router# configure terminal

 

Step 3

 

 

controller {t1e1} slot/port

Configures the T1 or E1 interface.

 

Example:

 

 

Router(config)# controller t1 0/4

 

Step 4

 

 

cem-group group-numberunframed

Assigns channels on the T1 or E1 circuit to the CEM channel. This

 

 

example uses the unframed parameter to assign all the T1 timeslots to the

 

Example:

CEM channel.

 

 

 

Router(config-if)# cem-group 4

 

 

unframed

 

Step 5

 

 

interface CEMslot/port

Configures the pseudowire interface to use for the new pseudowire class.

 

Example:

 

 

Router(config)# interface CEM0/4

 

Step 6

 

 

no ip address

Disables the IP address configuration for the physical layer interface.

 

Example:

 

 

Router(config)# no ip address

 

Step 7

 

 

cem group-number

Defines a CEM group.

 

Example:

 

 

Router(config-if)# cem 4

 

Step 8

 

 

xconnect ip-addressencapsulation

Binds an attachment circuit to the CEM interface to create a pseudowire.

 

mpls

This example creates a pseudowire by binding the CEM circuit 304 to the

 

 

remote peer 30.30.2.304.

 

Example:

 

 

Router(config-if-cem)# xconnect

 

 

30.30.30.2 304 encapsulation mpls

 

Step 9

 

 

exit

Exits configuration mode.

 

Example:

 

 

Router(cfg-if-cem-xconn)# exit

 

 

 

 

Note When creating IP routes for a pseudowire configuration, we recommend that you build a route from the xconnect address (LDP router-id or loopback address) to the next hop IP address, such as ip route
