Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter MPLS TE tunnel
interface view.
interface tunnel tunnel-number [ mode
mpls-te ]
N/A
3. Record routes or record
both routes and labels.
•
To record routes:
mpls te record-route
•
To record both routes and labels:
mpls te record-route label
By default, both route
recording and label
recording are disabled.
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 Command Remarks
1. Enter system view.
system-view
N/A
2. Enter MPLS TE tunnel
interface view.
interface tunnel tunnel-number
[ mode mpls-te ]
N/A
3. Enable loop detection.
mpls te loop-detection
By default, loop detection is
disabled.
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 Command Remarks
1. Enter system view.
system-view N/A
2. Enter MPLS TE tunnel
interface view.
interface tunnel tunnel-number
[
mode mpls-te
]
N/A
3. Set the maximum number of
tunnel setup attempts.
mpls te retry times
By default, the maximum number
of attempts is 3.
4. Set the retry interval.
mpls te timer retry seconds
By default, the retry interval is 2
seconds.
Configuring automatic bandwidth adjustment
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Enter MPLS TE view.
mpls te N/A
3. Enable automatic
bandwidth adjustment
globally, and configure
the output rate sampling
interval.
auto-bandwidth enable
[ sample-interval seconds ]
By default, the global auto
bandwidth adjustment is disabled.
The sampling interval configured in
MPLS TE view applies to all MPLS
TE tunnels. The output rates of all
