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 function, 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.
Configuring 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 configure tunnel setup retry:
Step
1.
Enter system view.
2.
Enter MPLS TE tunnel
interface view.
3.
Set the maximum number of
tunnel setup attempts.
4.
Set the retry interval.
Configuring automatic bandwidth adjustment
Step
1.
Enter system view.
2.
Enter MPLS TE view.
3.
Enable automatic
bandwidth adjustment
globally, and configure
the output rate sampling
interval.
