Chapter 21 Configuring Pseudowire
Configuring Pseudowire
Configuring a CESoPSN Pseudowire with UDP Encapsulation
Complete the following steps to configure a CESoPSN pseudowire with UDP encapsulation:
SUMMARY STEPS
1. enable
2. configure terminal
3. pseudowire-class pseudowire-class-name
4. encapsulation udp
5. ip local interface loopback interface-number
6. ip tos value value-number
7. ip ttl number
8. exit
9. controller {e1 | t1} slot/port
10. cem-group number timeslots number
11. exit
12. interface cem slot/port
13. no ip address
Step 6
interface CEM
slot/port
Example:
Router(config)# interface CEM0/5
Defines a CEM channel.
Step 7
cem
group-number
Example:
Router(config-if-cem)# cem 5
Defines a CEM channel.
Step 8
xconnect
ip-address
encapsulation
mpls
Example:
Router(config-if-cem)# xconnect
30.30.30.2 305 encapsulation mpls
Binds an attachment circuit to the CEM interface to create a pseudowire.
This example creates a pseudowire by binding the CEM circuit 5 to the
remote peer 30.30.30.2.
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.
Step 9
exit
Example:
Router(config-if-cem-xconn)# exit
Exits the CEM interface.
Step 10
end
Example:
Router(config-if-cem)# end
Exits configuration mode.
