====================================
2.4.2. Link TLV

   The Link TLV describes a single link.  It is constructed of a set of
   sub-TLVs.  There are no ordering requirements for the sub-TLVs.

   Only one Link TLV shall be carried in each LSA, allowing for fine
   granularity changes in topology.

I'm following 'Only one Link TLV shall be carried in each LSA'.  Well,
I prefer to say it must in OSPFv3 TE...

Neighbor-ID TLV is used for any type of link.  We can map each TE
information to each link using Neighbor-ID TLV.  CSPF runs on the
constraint topology information then generates ERO.  Of course to
generate ERO, IPv4/IPv6 address information is needed.  Interface IPv6
Address information is for that.
