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:

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. 

 

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.
