How Is This Braid Done?

[DJ1935]

I've been asked to make some bag handles similar to this. Can someone explain to me how to do this plait. I can do a standard four strand round but this one has two sets of three. Any assistance would be appreciated, thanks.

Looks like the 6strand round braid in o1-U2,o2-u1 pattern. You alternate the over/under braid for the left and right sides.
