backup-peer
Use backup-peer to configure a backup PW for a cross-connect, and enter cross-connect backup PW
view. If the backup PW has been configured, the command places you into cross-connect backup PW
view.
Use undo backup-peer to remove the backup PW from a cross-connect.

Parameters
ip-address: Specifies the LSR ID of the peer PE on the backup PW.
pw-id pw-id: Specifies a PW ID for the backup PW, in the range of 1 to 4294967295.
in-label label-value: Specifies the incoming label for the backup PW, in the range of 16 to 1023.
out-label label-value: Specifies the outgoing label for the backup PW, in the range of 16 to 1023.
pw-class class-name: Specifies a PW class by its name, a case-sensitive string of 1 to 19 characters. You
can configure the PW type and control word by specifying a PW class. If you do not specify any PW
class, the PW type is determined by the link type of the AC interface. The control word function is not
supported for PW types that do not require using control word.
tunnel-policy tunnel-policy-name: Specifies a tunnel policy by its name, a case-sensitive string of 1 to 19
characters. If you do not specify any tunnel policy, the default tunnel policy is used.
Usage guidelines
This command configures a backup PW to implement PW redundancy. The backup PW is used when the
primary PW fails.
To configure a backup static PW, you must specify the in-label and out-label. To configure a backup LDP
PW, you do not need to specify the in-label and out-label.
The peer LSR ID and PW ID specified for the backup PW must not be the same as those for any PW
bound to a cross-connect.
