How does the AP calculate the BSSID?

Here's the method to count the BSSID:

1. When you get the AP, you can see the LAN MAC addresses on the AP sticker.
Let's use 00:13:49:12:45:01 as an example.

2. The first BSSID of the 2.4GHz SSID will be 00:13:49:12:45:02 and the first BSSID of the 5GHz SSID will be 00:13:49:12:45:03.

3. The counting of continuous BSSID will apply the following formula:

VAP1  -  0X:13:49:00:12:YZ
VAP2  -  0X+2: YZ  :49:00:12 :Y((Z + 1)
VAP3  -  0X+2: YZ  :49:00:12 :Y((Z + 2)

4. So, the BSSID of 2.4GHz will be

BSSID1   ->   00:13:49:12:45:02
BSSID2   ->   02:02:49:12:45:03
BSSID3   ->   02:02:49:12:45:04
