Hello,

This is regarding the query for Locator TVL ,

As per the draft there is flags  D (L2-L1 leaking) and A (anycast ) defined.   Since there is space already exists for other flags , why can't  R flag is not defined in the main tlv.

Defining in main tlv when it had space, have some benefit as per me.

  1.  Many operator may opt to support main tlvs and may not support sub-sub-tvl.
  2.  Easy implantation and inter-op can  work with main tvl implementation itself.
I understand that rfc7794 can define extended prefix attribute tlv, for the same and   Locator tlv can sent with sub-sub-tlv define in rfc7794.

Regards
Parag
