Narrative:

While. On the glen rose arrival, traffic was called to us by ATC. We were able to identify the traffic because they had their landing light on. The traffic was on TCASII and I noted they were 600 ft below us and climbing at us at 12 O'clock position. Very soon after, we got a TCASII TA. I noted the traffic seemed to be turning to my left, so I turned to the right. ATC called and said to fly a north heading (my left). Right then we got a climb RA. We executed a climb while continuing a turn to the right, away from the traffic. It had become clear that the traffic had turned more to my left (or further west) to avoid us too. We maintained visual sight with the traffic the entire time and the TCASII RA went to a 'monitor vertical speed,' then 'clear of conflict.' our climb stopped at about 6800 ft. We then descended down to 5000 ft per ATC instructions and continued on the arrival. ATC said there was [no] conflict with any other traffic, but a report had to be filed. The traffic was clearly staying just below the class B airspace and soon it was clear, it was climbing fast. The traffic was also traveling straight down on STAR in the opposite direction. Class B airspace needs to extend further out toward the 4 corner posts here at dfw.

Title: SF34 FLC INITIATE EVASIVE MANEUVER DUE TO OPPOSITE DIRECTION TFC CLBING BELOW, THEN OUTSIDE DFW CLASS B AIRSPACE.

Narrative: WHILE. ON THE GLEN ROSE ARR, TFC WAS CALLED TO US BY ATC. WE WERE ABLE TO IDENT THE TFC BECAUSE THEY HAD THEIR LNDG LIGHT ON. THE TFC WAS ON TCASII AND I NOTED THEY WERE 600 FT BELOW US AND CLBING AT US AT 12 O'CLOCK POS. VERY SOON AFTER, WE GOT A TCASII TA. I NOTED THE TFC SEEMED TO BE TURNING TO MY L, SO I TURNED TO THE R. ATC CALLED AND SAID TO FLY A N HDG (MY L). RIGHT THEN WE GOT A CLB RA. WE EXECUTED A CLB WHILE CONTINUING A TURN TO THE R, AWAY FROM THE TFC. IT HAD BECOME CLR THAT THE TFC HAD TURNED MORE TO MY L (OR FURTHER W) TO AVOID US TOO. WE MAINTAINED VISUAL SIGHT WITH THE TFC THE ENTIRE TIME AND THE TCASII RA WENT TO A 'MONITOR VERT SPD,' THEN 'CLR OF CONFLICT.' OUR CLB STOPPED AT ABOUT 6800 FT. WE THEN DSNDED DOWN TO 5000 FT PER ATC INSTRUCTIONS AND CONTINUED ON THE ARR. ATC SAID THERE WAS [NO] CONFLICT WITH ANY OTHER TFC, BUT A RPT HAD TO BE FILED. THE TFC WAS CLRLY STAYING JUST BELOW THE CLASS B AIRSPACE AND SOON IT WAS CLR, IT WAS CLBING FAST. THE TFC WAS ALSO TRAVELING STRAIGHT DOWN ON STAR IN THE OPPOSITE DIRECTION. CLASS B AIRSPACE NEEDS TO EXTEND FURTHER OUT TOWARD THE 4 CORNER POSTS HERE AT DFW.
