Controlling Mpls Te Tunnel Setup - HP FlexNetwork 10500 Series Configuration Manual

Controlling MPLS TE tunnel setup

Before performing the configuration tasks in this section, be aware of each configuration objective
and its impact on your device.
Perform the tasks in this section on the ingress node of the MPLS TE tunnel.
Enabling route and label recording
Perform this task to record the nodes that an MPLS TE tunnel traverses and the label assigned by
each node. The recorded information helps you know about the path used by the MPLS TE tunnel
and the label distribution information, and when the tunnel fails, it helps you locate the fault.
To enable route and label recording:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Record routes or record
both routes and labels.
Enabling loop detection
Enabling loop detection also enables the route recording feature, regardless of whether you have
configured the mpls te record-route command. Loop detection enables each node of the tunnel to
detect whether a loop has occurred according to the recorded route information.
To enable loop detection:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Enable loop detection.
Setting tunnel setup retry
If the ingress node fails to establish an MPLS TE tunnel, it waits for the retry interval, and then tries to
set up the tunnel again. It repeats this process until the tunnel is established or until the number of
attempts reaches the maximum. If the tunnel cannot be established when the number of attempts
reaches the maximum, the ingress waits for a longer period and then repeats the previous process.
To set tunnel setup retry:
Step
1. Enter system view.
2. Enter MPLS TE tunnel
interface view.
3. Set the maximum number of
tunnel setup attempts.
