Rampant Ireland set up tantalising quarter-final rematch against New Zealand by condemning ragged rivals Scotland to another early World Cup exit with a crushing 36-14 bonus-point success in Paris.
Gregor Townsend’s men required a heroic win by eight points or more at Stade de France to snatch progression at the expense of their opponents.
But Test rugby’s top-ranked nation emphatically underlined their status with a thrilling display of attacking verve to avoid major drama in a feisty encounter.
James Lowe’s early try settled any nerves before Hugo Keenan crossed either side of a score from the recalled Iain Henderson to quickly take the game away from the shell-shocked Scots before the break.
Dan Sheehan and Garry Ringrose added to the embarrassment before Scottish pair Ewan Ashman and Ali Price claimed quickfire consolations.
Ireland will take on the All Blacks in the last eight, seeking to avenge the 46-14 thrashing suffered at the same stage of the 2019 World Cup in Japan.
Head coach Andy Farrell perhaps has cause for concern ahead of that showdown due apparent injuries suffered by wings Mack Hansen and Lowe.
Scotland, meanwhile, face an early flight home for the second successive tournament, with South Africa going through as Pool B runners-up to take on hosts France.
Premature departures for Blair Kinghorn, Jamie Ritchie and Darcy Graham due to fitness issues contributed to their woes, while Ollie Smith was shown a yellow card for causing a mass brawl.
The Scots came into the competition with one of their most talented teams in years but, following a chastening evening in the French capital, were left to rue being placed in the most difficult group alongside the reigning champions and the world’s number one team.
A deafening roar greeted the teams and the decibels were raised further among the dominant Irish support with just over a minute on the clock when Hansen sent Lowe over in the left corner after Ringrose dummied his way beyond Grant Gilchrist.
Scotland roared back and showed a statement of intent by kicking a series of penalties to the corner, forcing Ireland to ferociously repel prolonged pressure.
But their cause was not helped by losing full-back Kinghorn, whose 50th cap lasted just nine minutes, and captain Ritchie, while Ireland wing Hansen also went off.
Delightful slick interplay from right to left unlocked the Scottish backline, culminating in Ringrose teeing up the onrushing Keenan in the 27th minute, before Henderson marked his first start of the tournament by bulldozing over minutes later.
Far from thinking about the knock-out stages, Scotland trudged down the tunnel at the break fearing humiliation.
Ireland’s well-oiled machine led 26-0 ahead at that stage with a bonus point in the bag after Johnny Sexton set up Keenan’s second and then sent over his third successful conversion.
Players from both sides piled in, with Pierre Schoeman and Sheehan ploughing over an advertising board, before instigator Smith was sin-binned.
Sheehan was on the floor again minutes later, this time diving over to claim Ireland’s fifth try before Farrell wisely withdrew talisman Sexton, in addition to five of his forwards.
Jack Crowley’s fine cross-field kick sent over Ringrose before Scottish resistance finally materialised in the shape of a pair of well-taken scores, each converted by the largely subdued Finn Russell.
Replacement hooker Ashman made an immediate impact by galloping over on the right to ensure his side were not whitewashed, before scrum-half Price finished a fine team move.
Yet their endeavours mattered little as Ireland comfortably marched on thanks to a 17th successive win and a ninth in a row against the eliminated Scots.
