Usage guidelines
After you create a tunnel bundle interface in protection switching mode, you must specify a working
tunnel and a protection tunnel for the tunnel bundle interface. The two tunnels comprise an MPLS TE
tunnel bundle, which is an MPLS TE protection group. In the group, the device determines the tunnel for
traffic forwarding according to the external switching command and the signal fail indication. For
information about specifying the working tunnel and protection tunnel, see the member interface
command.
The device supports the following protection switching modes:
• 1:1 protection switching—Typically, traffic travels along the working tunnel. When either of the
following occurs, the ingress node selects the traffic forwarding tunnel (working or protection tunnel)
according to the protection state:
{ The ingress or the egress node detects a failure on the working tunnel.
{ An external switching command is executed on the node.
• 1+1 protection switching—Typically, traffic travels along both the working and protection tunnels,
and the egress node receives traffic from the working tunnel. When either of the following occurs,
the egress node determines from which tunnel it receives traffic according to the protection state:
{ The ingress or egress node detects a failure on the working tunnel.
{ An external switching command is executed on the node.
NOTE:
• The tunnel ingress or egress node can detect tunnel failures through MPLS BFD or other detection
mechanisms. For more information about MPLS BFD, see "Configuring MPLS OAM."
• The protection state indicates the comprehensive status of a PS protection

To create a tunnel bundle interface, you must specify the protection switching mode by using The
protection { oneplusone | onetoone } keywords. To enter the view of an existing tunnel bundle interface,
you do not need to specify the protection switching mode.
