Dear Authors,

The main TLV in extension LSAs indicates either Link or prefix information and sub TLVs can be properties/attributes of link or prefix.
Whether it is allowed to include other than Link or prefix information as main TLV in extension LSAs.
If I receive unknown TLV type/ other TLV types as main TLV in extension LSA, whether I need to ignore the TLV or I can discard the LSA itself.
Some places in draft mentioned, inclusion of particular main TLV types are strict to the particular extension LSA Types.
So whether we need to validate each main TLV type (it can be known but should not include in this particular LSA /unknown TLV type)  while processing extension LSAs ?

Regards,
