Configuring Mpls Te Tunnel Constraints - HP FlexNetwork 10500 Series Configuration Manual

Step
1. Enter system view.
2. Enter OSPF view.
3. Enable opaque LSA
advertisement and
reception.
4. Enter area view.
5. Enable MPLS TE for the
OSPF area.
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.
On IS-IS enabled interfaces, set the MTU to a minimum of 512 bytes to ensure that IS-IS LSPs of
different lengths can be flooded to the network.
To configure IS-IS TE:
Step
1. Enter system view.
2. Create an IS-IS process
and enter IS-IS view.
3. Specify a metric style.
4. Enable MPLS TE for the
IS-IS process.
5. Specify the types of the
sub-TLVs for carrying
DS-TE parameters.
