Which OSPF LSA is used to support MPLS Traffic-Engineering?
A.
NSSA LSA (Type 7)
B.
Opaque LSA (Type 11)
C.
Opaque LSA (Type 9)
D.
Opaque LSA (Type 10)
E.
External LSA (Type 5)
Explanation:
Type 10 – an area-local “opaque” LSA as defined by RFC2370. Opaque LSAs contain information
which should be flooded by other routers even if the router is not able to understand the extended
information itself.
Typically type 10 LSAs are used for traffic engineering extensions to OSPF, flooding extra
information about links beyond just their metric, such as link bandwidth and color.
