Usage guidelines
When loop detection is enabled on the ingress node of an MPLS TE tunnel, the route recording function
is automatically enabled for the tunnel, regardless of whether you have configured the mpls te
record-route command. When establishing the MPLS TE tunnel, each node of the tunnel detects whether
a loop has occurred according to the recorded route information.
Examples
# Enable loop detection for establishing MPLS TE tunnel 0.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
[Sysname-Tunnel0] mpls te loop-detection
mpls te record-route
Use mpls te record-route to enable route recording and label recording for the tunnel.
Use undo mpls te record-route to restore the default.
Syntax
mpls te record-route [ label ]
undo mpls te record-route
Default
A tunnel does not support route recording or label recording.
