Dear Authors,
While adverting prefixes for IPv6 Segment Routing (SRH support), the IPv6 prefixes  may not require to carry additional sub TLVs related to SRH some times.
So to identify prefixes are using for IPv6 Segment Routing, it may be helpful we add one option bit in prefix options like 'N' bit added for Node identification.

Please provide your opinion for adding new bit for IPv6 segment routing  in prefix options.

                        0  1  2  3  4  5  6  7
                    +--+--+--+--+--+--+--+--+
                    |  |  | N|DN| P| x|LA|NU|
                    +--+--+--+--+--+--+--+--+
