can't get signals to route as Diff pair

[kevinBP5MB]

I can't get eagle PCB to treat any of my signals as diff pairs, when routing.

I've defined signal names with a common prefix, and a suffix of _P and _N (example - CLK_122_P CLK_122_N).

I've defined a new new class - lvds_clk and set the trace with in the rules section.

I've put all the diff pairs in that class, and the signals select info the design manager confirms the diff pair trace signals are in the class.

Yet when I select route, and left click on ant of the signals, they don't route as a pair.

Hi @kevinBP5MB ,

I hope you're doing well. Right click on the route command and you'll see that you have several options, chose route differential pairs. 

Let me know if there's anything else I can do for you.

Best Regards,
