Examination requirements
Requirement 1) Add SW3/SW4/SW5/SW6 to the corresponding vlan (5point)
Requirement 2) To ensure network security, it is prohibited to connect from LSW3/LSW4/ LSW5/LSW6 switch receives BPDU,
the port will automatically close (5point) once received
Requirement 3) To ensure rapid network convergence, ensure that PC1/PC2/ PC3/PC4
The computer of PC5 forwards directly and immediately without going through listening-learning and other states (5point)
Requirement 4) SW1/SW2/SW3/SW4/SW5 /SW6 runs the MSTP protocol, ensuring that SW1 is the root of vlan10/vlan20
the backup root of vlan30 and vlan40, SW2 is the opposite of SW1, and configure instance 1=vlan10, instance 2=vlan20
, instance 3=vlan30, instance 4=vlan40(30-point)
Requirement 5) SW1/SW2 runs VRRP protocol, ensure that SW1 is the master device of vlan10/vlan20, vlan30 /
Backup device of VLAN 40, SW2 is opposite to SW1 (25point)
Requirement 6) Run OSPF on SW1/SW2/SW7/SW8/AR1, and plan Enter area 0 (30point)
Requirement 7) Perform path tracking on PC1/PC2 and perform path tracking on PC3/PC4/PC5

The test is as follows:
stp test
vrrp test
ospf test
Tracking testing mainly depends on the path
