Configure the TLV type of the
sub-TLV carrying DS-TE parameters
te-set-subtlv
{
bw-constraint
value
|
lo-multiplier
value
|
unreserved-bw-sub-pool
value
}
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.
NOTE:
•
For more information about IS-IS, see
Layer 3—IP Routing Configuration Guide.
•
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.

explicit path traverses the specified
node and the next node is a strict
node.
