PT #0 of bridge #1 collects and stores information about LD #2, which exists on bus ID #0 to which PT #0 belongs, through the transmission and reception of self-ID packets. Also PT #3 of bridge #2 collects and stores information about LD #4, which exists on bus ID #2 to which PT #0 belongs, through the transmission and reception of self-ID packets. Afterwards, BA #1 requests PT #0 of bridge #1 and PT #3 of bridge #2 to provide information about LD #2 and information about LD #4 respectively. Based on the provided information, the BA #1 connects LD #2 with LD #4.
