Level: 12.
Usage Guideline
This command can be used to enable PW redundancy of a VPWS service. It will create a backup PW.
The backup PW will have the same PW type and MTU as the primary PW. There should be one primary
PW and one backup PW set up for PW redundancy of the VPWS service. In a normal situation, the
primary PW is link up and the backup PW is link standby. The packet forwarding in the VPWS service will
take the primary PW. When the LDP hello procedure or other situations found the primary PW to be link
down, the backup PW will be changed to link up to do packet forwarding in the VPWS service.
If the primary PW is recovered later, the switch will either keep using the backup PW or switch back to the
primary PW base on the delay option setting. The local and remote labels for the backup PW are
automatically assigned and exchanged. Generally, when backup PW is setup, the primary PW label is
also automatically assigned.
The 802.1Q tunneling Ethernet type and VLAN mode of the backup PW will be the same as the primary
PW.
Only one backup PW can be configured.
Example
This example shows how to configure PW redundancy for a VPWS, which will add a backup PW to the
remote PE.
Switch# configure terminal
Switch(config)# interface ethernet 1/0/2
Switch(config-if)# service encapsulation svid 10
Switch(config-if-srv)# xconnect 130.1.1.2 2 encapsulation mpls
Switch(config-if-xconn)# backup peer 120.1.1.2 3
Switch(config-if-xconn)#
This example shows how to configure the switch to back up to the primary PW 10 seconds after the
primary PW comes back online.
Switch# configure terminal
Switch(config)# interface ethernet 1/0/2
Switch(config-if)# service encapsulation svid 10
Switch(config-if-srv)# xconnect 130.1.1.2 2 encapsulation mpls
Switch(config-if-xconn)# backup peer 120.1.1.2 3 delay 10
Specifies the peer LSR ID that is used to identify the other end
Provider Edge (PE).
Specifies the PW service instance ID. It is used to uniquely identify the
VPWS and it must be unique at both PEs. The range is from 1 to
4294967295.
(Optional) Specifies to switch back to the primary PW with the
specified delay time after the primary PW comes back. The range is
from 0 to 180 seconds.
(Optional) Specifies not to switch back to the primary PW even if it
comes back. This is the default option.
