Creating a protection group
To create an MPLS TE protection group:
1. Create a tunnel bundle interface in protection switching mode.
2. Specify two member interfaces for the tunnel bundle interface by using the member interface
command in tunnel bundle interface view: one for the working tunnel, and the other for the
protection tunnel.
In the protection group, the device determines the tunnel for traffic forwarding according to the external
switching command and the signal fail.
Follow these restrictions and guidelines when you create a protection group:
• You can bring up the tunnel bundle interface after the IP address and the tunnel destination address
for the tunnel bundle interface are configured and at least one of its member interfaces is up.
• HP recommends configuring the same tunnel destination address for the tunnel bundle interface
and its member interfaces. If they have different tunnel destination addresses, make sure the
member interfaces have a route to the tunnel bundle interface. Otherwise, traffic forwarding will
fail.
• The member interfaces for the tunnel bundle interface must be an MPLS TE tunnel interface.
• The member interfaces forwards only traffic whose output interface is the tunnel bundle interface.

Command Remarks
1. Enter system view.
system-view N/A
2. Create a tunnel bundle
interface in protection
switching mode, and enter its
view.
interface tunnel-bundle number
protection { oneplusone | onetoone }
By default, no tunnel bundle
interface exists on a device.
3. Specify a primary member
interface.
member interface tunnel
tunnel-number
By default, no primary member
interface is specified.
The MPLS TE tunnel for a primary
member interface is a working
tunnel.
4. Specify a backup member
interface.
member interface tunnel
tunnel-number protection
By default, no backup member
interface is specified.
The MPLS TE tunnel for a backup
member interface is a protection
tunnel.
5. Configure an IPv4 address for
the tunnel bundle interface.
ip address ip-address { mask |
mask-length } [ sub ]
By default, no IPv4 address is
configured.
6. Configure the destination
address for the tunnel bundle
interface.
destination ip-address
By default, no tunnel destination
address is configured.
7. (Optional.) Configure a
description for the tunnel
bundle interface.
description text
By default, the description of a
tunnel bundle interface is
Tunnel-Bundlenumber Interface,
for example, Tunnel-Bundle1
Interface.
