Use the xconnect backup command to enable the PW redundancy of VPWS
service on the interface. Use the no xconnect backup command to cancel the
PW redundancy of VPWS service.
Specifies the PW (pseudo-wire) service instance ID. It is used to uniquely identify
the VPWS (Virtual Private Wire Service) and it must be unique at both PEs
(Provider Edge). The range is 1-4294967295.
Specifies the peer LSR ID that is used to identify the other end PE.
No PW redundancy of VPWS on interface.
Interface configuration mode.
This command can be used to enable PW redundancy of a VPWS service. It will
create a backup pseudowire service. Before this command is executed, VPWS
service i.e. primary pseudowire must be existed. The backup pseudowire will
have same PW type and MTU with primary pseudowire.
There should be one primary pseudowire and one backup pseudowire set up for
PW redundancy of VPWS service. In a normal situation, the primary pseudowire
is link up and the backup pseudowire is link standby. The packet forwarding in
the VPWS service will work in the primary pseudowire. But when LDP hello
procedure or other situations found primary pseudowire link down happens,
backup pseudowire will be changed to link up to take packet forwarding in the
VPWS service. After primary pseudowire is recovered to link up again, backup
pseudowire will be back to link standby, and the packet forwarding in the VPWS
service will be back to primary pseudowire again.
The follows example shows how to configure PW redundancy for a VPWS, which
will add a backup PW to another PE.
