While executing the LDA DME 25 into EGE in CAVOK weather conditions; we received a low altitude warning from the ATC tower controller. We were descending on the RNAV arrival in managed mode on the Airbus and was coming from 'VOAXA intersection' to 'AQULA intersection' descending from 13;800 feet to 12;900 feet that is charted. The aircraft did start a little higher descent rate out of 13;800 feet to 12;900 feet to cross 'AQULA intersection' at 12;900 feet but was right on path at that fix {AQULA} . Speed was coming from I believe 180 knots down to 160 knots at that same time. That is when ATC showed an Altitude Alert and to check altitude and altimeter setting {30.48 I believe}. Ridge line was in plain sight and no other issues after that.
We were about 170 knots above or at all altitudes on the approach. The altimeter settings were correct with the latest tower call about 2 min earlier. We were in very clear VFR conditions and there was no indication from the cockpit there was any issue with terrain.
ATC called an Airbus crew with a low altitude alert while the aircraft was on the LDA DME RWY 25 to EGE descending at slightly higher than normal rate but on profile with the terrain in sight.
