Usage guidelines
OSPF TE uses Type-10 opaque LSAs to carry the TE attributes for a link. Before you configure OSPF TE,
you must enable opaque LSA advertisement and reception by using the opaque-capability enable
command. For more information about opaque LSA advertisement and reception, see Layer 3—IP
Routing Configuration Guide.
Examples
# Enable MPLS TE for OSPF process 1 in OSPF area 1.

Parameters
bandwidth: Provides bandwidth protection for the primary CRLSP. If you do not specify this keyword,
bandwidth protection is not provided for the primary CRLSP.
Usage guidelines
FRR provides a quick link or node protection on a CRLSP. FRR traffic switching can happen in as fast as
50 milliseconds, minimizing data loss.
After FRR is enabled for an MPLS TE tunnel, once a link or node fails on the primary CRLSP, the following
events occur:
• FRR reroutes the traffic to a bypass tunnel.
