The Indian Directors General of Military Operations (DGMO) will contact his Pakistan counterpart over the hotline between the two sides to take up the issue, sources said.
The Indian Army has already vowed an "appropriate" response to the "despicableact". The Pakistan army has denied that it was involved in the attack.
Defence Minister Arun Jaitley had said yesterday that the "sacrifice (of the two killed) will not go in vain" and the Indian armed forces will react "appropriately" to the "inhuman act" of the Pakistani troops.
The soldiers killed were Naib Subedar Paramjeet Singh of 22 Sikh Infantry and Head Constable Prem Sagar of 200th Battalion of BSF.
