Chapter 4 Configuring the Cisco MWR 2941 Router Using the CLI
Configuration Sequence
• maximum-value—The value of the largest label allowed in the label space. The default is
platform-dependent.
• static—(Optional) Reserves a block of local labels for static label assignments. If you omit the static
keyword and the minimum-static-value and maximum-static-value arguments, no labels are
reserved for static assignment.
• minimum-static-value—(Optional) The minimum value for static label assignments. There is no
default value.
• maximum-static-value—(Optional) The maximum value for static label assignments. There is no
default value.
Router(config)# mpls label range min-label max-label [static min-static-label-value
max-static-label-value]
Step 2 Use the xconnect command to define a static pseudowire and enter pseudowire label configuration
mode:
Router(config-if-xconn)# xconnect 20.20.1.2 50 encapsulation mpls manual
Step 3 Use the mpls label command to apply an MPLS label to the pseudowire interface.
Router(config-if-xconn)# mpls label local-vc-label remote-vc-label
Step 4 Use the mpls control-word command to enable or disable a control word on the pseudowire connection.
Router(config-if-xconn)# mpls control-word
You can use the show mpls l2transport vc detail and ping mpls pseudowire commands to verify your
configuration.
Configuring a Backup Peer
A backup peer provides a redundant pseudowire (PW) connection in the case that the primary PW loses
connection; if the primary PW goes down, the Cisco MWR 2941 diverts traffic to the backup PW. Follow
these steps to configure a backup peer.
Step 1 Use the backup peer command to define the address and VC of the backup peer.
Router(config)# backup peer peer-router-ip-address vcid [pw-class pw-class name]
Step 2 Use the backup delay command to specify the delay before the router switches pseudowire traffic to the
backup peer VC.
Router(config)# backup delay enable-delay {disable-delay | never}
Where:
• enable-delay—The time before the backup PW takes over for the primary PW.
• disable-delay—The time before the restored primary PW takes over for the backup PW.
• never—Disables switching from the backup PW to the primary PW.
