the interface through the sub-TLV of IS reachability TLV (type 22). As a best practice, avoid enabling
IS-IS TE on an interface configured with secondary IP addresses.
For more information about IS-IS, see Layer 3—IP Routing Configuration Guide.
To configure IS-IS TE:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Configure the wide metric
attribute of IS-IS.
4. Enable IS-IS TE.
5. Configure the TLV type of the
sub-TLV carrying DS-TE
parameters.
Configuring an MPLS TE explicit path
An explicit path is a set of nodes. The relationship between any two neighboring nodes on an explicit
path can be either strict or loose.
•
Strict—The two nodes are directly connected.
•
Loose—The two nodes have devices in between.
When inserting nodes to an explicit path or modifying nodes on it, you can configure the include
keyword to have the established LSP traverse the specified nodes or the exclude keyword to have
the established LSP bypass the specified nodes.
When establishing an MPLS TE tunnel between areas or ASs, use a loose explicit route, specify the
ABR or ASBR as the next hop of the route, and make sure the tunnel's ingress node and the ABR or
ASBR can reach each other.
To configure an MPLS TE explicit path:
Step
1. Enter system view.
2. Create an explicit path for
MPLS TE tunneling and
enter its view.
3. Add a node to the explicit
path.

Remarks

N/A
By default, IS-IS uses narrow
metric style.
Disabled by default.
Optional.
By default, the bw-constraint
parameter is carried in sub-TLV
252, the lo-multiplier parameter
in sub-TLV 253, and the
unreserved-bw-sub-pool
parameter in sub-TLV 251.
Remarks

Optional.
By default, the include keyword
and the strict keyword apply. The
explicit path traverses the
specified node and the next node
is a strict node.
