Creating A Protection Group - HP MSR2000 Configuration Manual

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.

To create a protection group:
Step
1. Enter system view.
2. Create

switching mode, and enter its
view.
3. Specify a primary member
interface.
4. Specify a backup member
interface.
5. Configure an IPv4 address for
the tunnel bundle interface.
6. Configure
address for the tunnel bundle
interface.

Remarks
N/A
By default, no tunnel bundle
interface exists on a device.
By default, no primary member
interface is specified.
The MPLS TE tunnel for a primary
member interface is a working
tunnel.
By default, no backup member
interface is specified.
The MPLS TE tunnel for a backup
member interface is a protection
tunnel.
By default, no IPv4 address is
configured.
By default, no tunnel destination
address is configured.
By default, the description of a
tunnel bundle interface is
Tunnel-Bundlenumber Interface,
for example, Tunnel-Bundle1
Interface.
