The OSPFv3 extensions support the following TLVs:
a prefix SID that is a sub-TLV of the OSPFv3 prefix TLV
The OSPFv3 prefix TLV is a new top-level TLV of the extended prefix LSA introduced in draft-ietf-ospf-ospfv3-lsa-extend. The OSPFv3 instance can operate in either LSA sparse mode or extended LSA mode.
The config>router>extended-lsa only command advertises the prefix SID sub-TLV in the extended LSA format in both cases.
an adjacency SID that is a sub-TLV of the OSPFv3 router-link TLV
The OSPFv3 router-link TLV is a new top-level TLV in the extended router LSA introduced in draft-ietf-ospf-ospfv3-lsa-extend. The OSPFv3 instance can operate in either LSA sparse mode or extended LSA mode. The config>router>extended-lsa only command advertises the adjacency SID sub-TLV in the extended LSA format in both cases.
the SR-Algorithm TLV and the SID/Label range TLV
Both of these TLVs are part of the TLV-based OSPFv3 Router Information Opaque LSA defined in RFC 7770.
