To do...
Configure the wide metric attribute
of IS-IS
Enable IS-IS TE
Configure the TLV type of the
sub-TLV carrying DS-TE parameters
NOTE:
For more information about IS-IS, see
•
• IS-IS TE does not support secondary IP address advertisement. With IS-IS TE enabled on an interface
configured with multiple IP addresses, IS-IS TE advertises only the primary IP address of the interface
through the sub-TLV of IS reachability TLV (type 22). HP does not recommend enabling IS-IS TE on an
interface configured with secondary IP addresses.
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 may 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.
To configure an MPLS TE explicit path:
To do...
Enter system view
Create an explicit path for MPLS TE
tunneling and enter its view
Add a node to the explicit path
Use the command...
cost-style { narrow | wide |
wide-compatible | { compatible |
narrow-compatible }
[ relax-spf-limit ] }
traffic-eng [ level-1 | level-2 |
level-1-2 ]
te-set-subtlv { bw-constraint value
| lo-multiplier value |
unreserved-bw-sub-pool value }
Layer 3—IP Routing Configuration Guide
Use the command...
system-view
explicit-path path-name [ disable |
enable ]
add hop ip-address1 [ include
[ loose | strict ] | exclude ] { after |
before } ip-address2

Remarks
Required
By default, IS-IS uses narrow metric
style.
Required
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
––
Required
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.
