RT86U interfaces description

[Deleted member 62525]

Running latest 386.1_2 on RT-86U and have a question about the interfaces.
I know that br0 is a router IP and eth0 is WAN IP. What is br1 interface and what is it used for?
I see that it has IP assigned of 192.168.101.1, br0 has 192.168.50.1

There is no such thing as an RT-86U. It's either an RT-AC86U or RT-AX86U.

br1 is used for Guest Network 1.
