Ethiopia were forced to wait until the second half to score two crucial goals that earned them a 2013 Nations Cup final berth at the expense of favourites Sudan
The visitors started the match with promise but could not get past a well marshalled defence.
Ethiopia meanwhile, took much time in settling in this match and failed to carve out any real goal scoring opportunities in the first half, which ended goalless.
The second period started with urgency and much penetration from the home side who were rewarded on 70 minutes, after Alula Girima beat the Sudanese defence to slot home the opening goal.
The 20-year-old Saint George fullback then sealed the points with an opportunistic strike in the final 10 minutes of the game to send the majority of the crowd at the national stadium into a frenzy.
The result edged a thrilling two legged clash between the East African Nations that shared 10 goals and saw the latter qualify through the away goals rule.
Sudan, who had won the first leg played in Khartoum 5-3, were seeking to qualify to the bi-annual continental showpiece for the second consecutive time but paid a heavy price for their initial cautious approach.
