Six stations (S1-S6) are comnected to an extended LAN through transparent bridges (B1 and B2), as shown in the figure below. Initially, the forwarding tables are empty. Suppose the following stations transmit frames: S2 transmits to S1, S5 tsransmits to S4, S3 transmits to S5, S1 transmits to S2, and s6 tansnits to S. Fill in the forwarding tables with appropriate entries after the frames have been completely S1 S4 56 LANI LAN2 LAN3 port 2 port 1 port 2 Six stations (S1-S6) are comnected to an extended LAN through transparent bridges (B1 and B2), as shown in the figure below.
