RB5009UG+S+IN <=> XQ+BC0003-XS+ <=> CRS504-4XQ-IN?

So i’m reading this for the CRS504:“In fact, you can mix and match all kinds of connections this way: 100 Gigabits on one port, 40 Gigabits on the other, 4x25 Gigabits on the third, and maybe even some 10G or 1G cables on the fourth”

So I got myself: RB5009 <=> XQ+BC0003-XS+ <=> CRS504-4XQ-IN
It shows the cable type on sfp info , but no link . Should it work? Or how else would I get some real connection to that quad 100Gbe switch.

Should it even work?

Why do you put a 100Gb → 4x25Gb breakout cable in a router with only 10Gb as max on SFP+ port ?
You read the specs for CRS504 but not for RB5009 ?

Use a simple DAC and it will connect at 10Gb, I would think.
