Chapter 21 Configuring Pseudowire
Configuring L2VPN Pseudowire Redundancy
Step 4
framing {sf | esf}
Example:
Router(config-controller)# framing
esf
Selects the T1 framing type.
Step 5
exit
Example:
Router(config-controller)# exit
Exits the controller configuration mode.
Step 6
interface cem
slot/port
Example:
Router(config)# interface cem0/0
Configures the pseudowire interface to use for the new pseudowire class.
Step 7
cem
group-number
Example:
Router(config-if)# cem 0
Configures the pseudowire interface to use for the new pseudowire class.
Step 8
xconnect
peer-router-id
vcid
{encapsulation mpls | pw-class
pw-class-name
}
Example:
xconnect 10.10.10.11 344
encapsulation mpls
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 to assign to the pseudowire. The same vcid
must be used for both ends of the pseudowire.
• encapsulation mpls sets MPLS for tunneling mode.
• pw-class-name specifies a pseudowire class that includes the
encapsulation mpls command.
Note The peer-router-id and vcid combination must be unique on the
router.
Step 9
backup peer
peer-router-ip-address
vcid
[pw-class
pw-class-name
]
Example:
Router(config-if-xcon)# backup peer
10.10.10.11 344 [pw-class pwclass1]
Specifies a redundant peer for the pseudowire VC.
The pseudowire class name must match the name specified when you
created the pseudowire class, but you can use a different pw-class in the
backup peer command than the name used in the primary xconnect
command.
Step 10
backup delay
enable-delay
{
disable-delay
| never}
Example:
Router(config-if-xcon)# backup
delay 30 60
• enable delay—Specifies how long (in seconds) the backup
pseudowire VC should wait to take over, after the primary pseudowire
VC goes down. The range is 0 to 180.
• disable delay—Specifies how long the primary pseudowire should
wait, after it becomes active to take over for the backup pseudowire
VC. The range is 0 to 180 seconds. If you specify the never keyword,
the primary pseudowire VC never takes over for the backup.
