Parameters
hold-time value: Specifies the period of time that IGP waits to advertise a down event of the MPLS TE
tunnel, in the range of 0 to 4294967295 milliseconds. The default value is 0, which means when the
MPLS TE tunnel is down, IGP immediately advertises the tunnel down event.
Usage guidelines
Forwarding adjacency is a method to direct traffic to an MPLS TE tunnel or tunnel bundle.
After forwarding adjacency is enabled on the tunnel ingress node, the ingress node advertises the MPLS
TE tunnel or tunnel bundle as a link in the network through the IGP. Therefore, all devices in the IGP
network can use the MPLS TE tunnel or tunnel bundle in their IGP route calculation.
To make forwarding adjacency take effect, you must establish two MPLS TE tunnels or tunnel bundles in
opposite directions between two nodes, and enable forwarding adjacency on both the nodes.
On the same tunnel interface or tunnel bundle interface, the mpls te igp advertise command and the
mpls te igp shortcut command cannot both take effect. The newly configured command overwrites the
previous command.
The hold-time configuration for a tunnel interface does not take effect after the tunnel interface becomes
a tunnel bundle member interface.
Examples
# Enable forwarding adjacency for MPLS TE tunnel 0, and configure IGP to advertise the tunnel down
event 10000 milliseconds after the tunnel is down.
<Sysname> system-view
[Sysname] interface tunnel 0 mode mpls-te
[Sysname-Tunnel0] mpls te igp advertise hold-time 10000

mpls te igp metric
Use mpls te igp metric to assign a metric to an MPLS TE tunnel or tunnel bundle.
Use undo mpls te igp metric to restore the default.
Syntax

undo mpls te igp metric
Default
The metric of an MPLS TE tunnel or tunnel bundle equals its IGP metric.
