LSA types

Type 1 ( Router ) , Type 4 ( ASBR summary ), Type 7 ( External in NSSA), and Type 8 (OSPF External Attributes LSA)

Traffic-engineering information is advertised in OSPF type-10 LSAs
These are opaque LSAs and have area flooding scope, which is why
you cannot have TE tunnels running through multiple areas
