Chapter 21 Configuring Pseudowire
Configuring Pseudowire
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
30.30.30.2 255.255.255.255 1.2.3.4.
Command Purpose
Step 1
enable
Example:
Router> enable
Enables privileged EXEC mode.
• Enter your password if prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters global configuration mode.
Step 3
controller {t1|e1}
slot/port
Example:
Router(config)# controller t1 0/4
Configures the T1 or E1 interface.
Step 4
cem-group
group-number
unframed
Example:
Router(config-if)# cem-group 4
unframed
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
CEM channel.
Step 5
interface CEM
slot/port
Example:
Router(config)# interface CEM0/4
Configures the pseudowire interface to use for the new pseudowire class.
Step 6
no ip address
Example:
Router(config)# no ip address
Disables the IP address configuration for the physical layer interface.
Step 7
cem
group-number
Example:
Router(config-if)# cem 4
Defines a CEM group.
Step 8
xconnect
ip-address
encapsulation
mpls
Example:
Router(config-if-cem)# xconnect
30.30.30.2 304 encapsulation mpls
Binds an attachment circuit to the CEM interface to create a pseudowire.
This example creates a pseudowire by binding the CEM circuit 304 to the
remote peer 30.30.2.304.
Step 9
exit
Example:
Router(cfg-if-cem-xconn)# exit
Exits configuration mode.
