Stuart McCall’s side won the first leg 2-0 at Ibrox in Glasgow on Wednesday evening.
Nicky Clark put Rangers in the lead on the stroke of half time, and Kenny Miller scored the second in the 63rd minute.
Newcastle United-owned attacking midfielder Haris Vuckic played a key role in both of those goals, as the youngster continued to show his qualify for the Scottish giants.
Over the course of the 90 minutes, Rangers had 53% of the possession, took six shots of which five were on target, and earned one corner.
Visiting Hibs had 47% of the possession, but the visitors took eight shots of which only one was target and earned 13 corners.
"I couldn't believe Hibs kept doing the same thing from all of those corners,” former Rangers midfielder Ferguson told BBC Sport.
“Rangers coped easily. What Rangers did well was to deny Hibs space and they didn't have a clue how to break them down.
“I enjoyed watching Hibs in the first half but I don't think they handled the second half well at all. On Saturday it will be the same, Rangers can sit back and hit on the break.”
The second leg of the playoff semi-final will be held at Easter Road on Saturday. Rangers will head into the game as favourites, as they have a two-goal lead.
However, the Gers should not get complacent. If Hibernian get an early goal, then it could become tough for Rangers.
The Glasgow giants need to keep it tight at the back, but at the same time they should not sit too deep and be under pressure all the time.
