Hi ,
      Lmp drafts tells that Message ID should be monotonically increasing .

      Section 7 also tells that "Unacknowledge messages sent with Message_id
object should be retransmitted until the message is
      acknowledged or until retry limit is reached."

      Do we have to sent all retransmitted messages with the same Message Id
as sent previously or it should be in monotonically
      increasing order.

Hi Manoj,

An unacknowledged message could have been lost; i.e. might not have reached
the neighbor. So, the neighbor has no way of determining if a message is
a re-transmit and will fail [and nack] a message with out-of-order message-id.

So, re-transmit attempts should increase message id.
