Clermont showed the depth of their resources on Saturday as their youthful side won 17-0 in Toulon.
Stade Français were brought down to earth with a bump after being on the receiving end of thrashing in Castres.
The other big winners of the early games in Round Two were Racing-Métro, who ended their duck against Perpignan by romping to a bonus-point win.
There were two shock results, the first coming in Montpellier where last season's losing finalists were upset by Brive. The second was in Biarritz where the Basque giants were held to a 9-9 draw by Agen.
In Saturday's late game, Bordeaux picked up their first win of the season after overcoming Bayonne 18-6 in a kick-fest at Stade André Moga.
Biarritz 9-9 Agen
Castres 35-10 Stade Français
Montpellier 12-28 Brive
Racing Métro 47-13 Perpignan
Toulon 0-17 Clermont
Bordeaux 18-6 Bayonnais
To follow on Sunday: Lyon v Toulouse
Racing-Métro 47-13 USA Perpignan
Stade Yves Du Manoir - Colombes (Paris)
In glorious sunshine on the outskirts of Paris, Racing-Métro claimed their first win against Perpignan since returning to the top division.
It took over half-an-hour to for the hosts to get over the whitewash, but once Henry Chavancy had claimed les Franciliens' first try, four more would follow as Racing outscored their visitors five tries to two to grab a bonus point.
USAP started well enough, dominating the opening exchanges to lead 9-6 on the half-hour mark before the wheels came off.
Chavancy touched down a second time just before the break to give Racing a 23-9 half-time lead.
Racing weren't necessarily playing open rugby but when Fijian wing Virimi Vakatawa created a try for Jonathan Wisniewski just after the restart before scoring himself, the hosts raced to a 37-9 lead!
Perpignan made a late comeback, scoring two tries in the final quarter through South Africans Gavin Hume and Rudi Coetzee but hooker Thomas Bianchin's late score secured all five points for Racing.
Ryan Cross made his debut for Perpignan, but was unable to make much of an impact.
Biarritz Olympique 9-9 SU Agen
Parc des Sports d'Aguilera, Biarritz
Agen are making a habit of finishing strongly and almost claimed their second win on the road in as many weeks.
Valentin Courrent missed an 80th minute penalty that would have handed his side victory in wet conditions on the Basque coast.
BO enjoyed the lion's share of possession in the first-half which ended 6-6.
In the end Biarritz's Samoan lock Pelu Taele-Pavihi's yellow card for high tackle cost his side two championship points as it allowed Courrent to level matters just three minutes from time.
Castres Olympique 35-10 Stade Français Paris
Stade Pierre Antoine, Castres
What a difference a week can make! Last Saturday, Castres looked lost while Stade Français ran rampant - but it was the complete opposite this weekend as the Parisians were outplayed in every sector.
Castres led from start to finish with wing Marc Andreu grabbing a try in each half as the hosts bagged a bonus-point win.
Castres were ahead 23-3 at the break. Stade full-back Paul Warwick set up a late try for Fijian Alexander Rokobaro but Castres had the last laugh as Chris Masoe crashed over to secure the bonus point.
Montpellier HR 12-28 CA Brive Corrèze
Stade Yves Du Manoir, Montpellier
Few would have expected this result but Brive thoroughly deserve their first win of the season having totally outplayed their hosts.
It was all square at 9-9 at half-time but les Brivistes made their domination count in final quarter as wings Jacques Boussuge and Clement Marienval each scored.
Fly-half Raphael Lagarde landed all of Montpol's points from the kicking tee but their second loss means they'll finish the weekend in last place in the standings.
RC Toulon 0-17 ASM Clermont Auvergne
Stade Felix Mayol, Toulon
It wasn't a good game to watch at Felix Mayol by any means as handling errors were compounded by some wayward kicking, but Clermont will still be delighted by the result from their youthful team.
While Toulon started the first half breathing fire before fading, Clermont gradually built momentum and took an 11-0 lead into the break thanks to a try from 20-year-old full-back Jean-Marcellin Buttin via passes from Brent Russell and Regan King.
Clermont fly-half Brock James added two penalties in the second half to go with his two from the first. It was an entirely different story for the home side's kickers as Benjamin Lapeyre, Julien Dumora and Andre Pretorius couldn't score land a single penalty between them.
Bordeaux-Bègles 18-6 Aviron Bayonnais
Stade Jacques Chaban-Delmas, Bordeaux
Bordeaux claimed their first victory of the 2011/12 Top 14 season thanks to eighteen points from the boot of pivot Gerard Frazer in Saturday's late game against Bayonne.
The home side's fly-half knocked over six penalties to opposing scrum-half Cedric Garcia's two as the visitors could not manage to back up their round one success over Toulouse.
