Configuring OSPF TE
Configure OSPF TE if the routing protocol is OSPF and a dynamic signaling protocol is used for MPLS
TE tunnel setup.
The OSPF TE extension uses Opaque Type 10 LSAs to carry TE attributes of links. Before configuring
OSPF TE, you need to enable the opaque capability of OSPF. In addition, for TE LSAs to be generated,
at least one neighbor must be in full state.
Follow these steps to configure OSPF TE:
To do...
Enter system view
Enter OSPF view
Enable the opaque LSA
capability
Enter OSPF area view
Enable MPLS TE in the OSPF
area
Exit to OSPF view
For more information about OSPF opaque LSA, refer to OSPF Configuration in the IP routing
volume.
MPLS TE cannot reserve resources and distribute labels on OSPF virtual links, that is, MPLS TE
cannot establish an LSP tunnel through an OSPF virtual link. Therefore, make sure there is no
virtual links in the OSPF routing domain when configuring OSPF TE.
Configuring IS-IS TE
Configure IS-IS TE if the routing protocol is IS-IS and a dynamic signaling protocol is used for MPLS TE
tunnel setup. In case both OSPF TE and IS-IS TE are available, OSPF TE takes priority.
The IS-IS TE extension uses the sub-TLV of IS reachability TLV (type 22) to carry TE attributes. Before
configuring IS-IS TE, you need to configure the IS-IS wide metric style, which can be wide, compatible,
or wide-compatible.
