RBR20 MAC Address for ISP new Router Passthrough Setup

[ketcdm]

I just got a replacement gateway router from my ISP provide and I have to set up my Orbi RBR20+1 satellite.  The ISP requires that I enter the MAC address for the RBR20, however it is not in a format that is acceptable to the ISP.  The label on the bottom shows the MAC as a 12 digit number.  The ISP needs it in this format:  xx:xx:xx:xx:xx:xx.  Do I just type in the colons after every second number or am I missing some information?  My ISP is AT&T and I'm trying to connect the RBR20 to ARRIS/ATT WIFI Gateway
BGW201-700.  Thanks for your help.
