5.
Enable MPLS TE for the
OSPF area.
mpls te enable
By default, an OSPF area does not
support MPLS TE.
Configuring IS-IS TE
IS-IS TE uses a sub-TLV of the extended IS reachability TLV (type 22) to carry TE attributes.
Because the extended IS reachability TLV carries wide metrics, specify a wide metric-compatible
metric style for the IS-IS process before enabling IS-IS TE. Available metric styles for IS-IS TE
include wide, compatible, or wide-compatible. For more information about IS-IS, see Layer 3—IP
Routing Configuration Guide.
To make sure IS-IS LSPs can be flooded on the network, specify an MTU that is equal to or greater
than 512 bytes on each IS-IS enabled interface, because of the following:
• The length of the extended IS reachability TLV might reach the maximum of 255 bytes.
• The LSP header takes 27 bytes and the TLV header takes two bytes.
• The LSP might also carry the authentication information.
To configure IS-IS TE:
Step
Command
Remarks
1. Enter system view.
system-view
N/A
2. Create an IS-
IS process
and enter IS-IS view.
isis
[ process-id ] By default, no IS-IS process exists.
3. Specify a metric style.
cost-style
{
wide
|
wide-compatible
|
compatible
[
relax-spf-limit
] }
By default, only narrow metric style
packets can be received and sent.
For more information about this
command, see Layer 3—IP Routing
Command Reference.
4.
Enable MPLS TE for the
IS-IS process.
mpls te enable
[
Level-1
|
Level-2
]
By default, an IS-IS process does
not support MPLS TE.
5. Specify the types
of the
sub-TLVs for carrying
DS-TE parameters.
te-subtlv
{
bw-constraint
value |
unreserved-bw-sub-pool
value } *
By default, the
bw-constraint
parameter is carried in sub-TLV
252, and the
unreserved-bw-sub-pool
parameter is carried in sub-TLV
251.
Configuring MPLS TE tunnel constraints
Perform this task on the ingress node of the MPLS TE tunnel.

required for the tunnel, and
specify a CT for the tunnel's
traffic.
