Configuring Pseudowire Redundancy
The following figure shows an example of pseudowire redundancy.
Figure 14: Pseudowire Redundancy
To configure pseudowire redundancy on a SPA-1CHOC3-CE-ATM, SPA-2CHT3-CE-ATM, or
SPA-24CHT1-CE-ATM perform the following steps.
You must configure the backup pseudowire to connect to a router that is different from the primary
Note
pseudowire.
SUMMARY STEPS
1. Router# enable
2. Router# configure terminal
3. Router(config)# interface cem slot/subslot/port
4. Router(config-if)# cem group-number
5. Router(config-if-cem)# xconnect peer-router-id vcid {encapsulation mpls | pw-class pw-class-name}
6. Router(config-if-cem-xconn)# backup peer peer-router-ip-addr vcid [pw-class pw-class-name]
DETAILED STEPS
Command or Action
Step 1 Router# enable
Step 2 Router# configure terminal
Step 3 Router(config)# interface cem
slot/subslot/port
Step 4 Router(config-if)# cem group-number
Step 5 Router(config-if-cem)# xconnect
peer-router-id vcid {encapsulation mpls |

Configuring the Circuit Emulation over Packet Shared Port Adapter
Purpose
Enters the Privileged EXEC mode.
Enters the global configuration mode.
Selects the CEM interface where the CEM circuit (group) is located (where
slot/subslot is the SIP slot and SPA subslot and port is the SPA port where
the interface exists).
Selects the CEM circuit (group) to configure a pseudowire.
Configures a pseudowire to transport TDM data from the CEM circuit
across the MPLS network.
• peer-router-id is the IP address of the remote PE peer router.
• vcid is a 32-bit identifier assigned to the pseudowire. The same vcid
must be used for both ends of the pseudowire.
