3. Consider this switched network. Assume that Spanning Tree Protocol (STP) is running on this network. Fa interfaces run at 100 Mbps and G interfaces run at 1 Gbps. The table below shows the Bridge ID (BID) value for each switch, split into Priority and MAC Address parts. All ports are on VLAN 1. Assume that all links have default costs. S1 Fa0/2 Fa0 R1 GO/2 Host Fa0/1 Fa0/0 Fa0/1 GO/2 Fa0/2 GO/1 GO/2 S2 S3 Switch Priority MAC Address S1 32769 0010.2222.EE07 S2 32769 0020.1111.ABCD S3 28673 0030.4444.3511 a. (5 points) When STP protocol is run, which switch (S1, S2 or S3) will become the Root Switch for this network? Why?
