Step 13: Configure Subinterface Fa0/0
BR4#configure terminal
BR4(config)#interface Fa0/0
BR4(config-if)#no shut
BR4(config-if)#interface Fa0/0.1
BR4(config-subif)#description VLAN1
BR4(config-subif)#encapsulation dot1q 1
BR4(config-subif)#ip address 10.0.0.1 255.255.255.0
BR4(config-subif)#interface Fa0/0.10
BR4(config-subif)#description VLAN10
BR4(config-subif)#encapsulation dot1q 10.
BR4(config-subif)#ip address 10.10.10.254 255.255.255.0
BR4(config-subif)#interface Fa0/0.20
BR4(config-subif)#description VLAN20
BR4(config-subif)#encapsulation dot1q20
BR4(config-subif)#ip address 10.10.20.254 255.255.255.0
BR4(config-subif)#end
BR4#

Step 14: Configure two hosts for server VLAN, and two hosts for end user VLAN
a. H1 and H3 should be given IP addresses in the Servers VLAN, with a default gateway of
10.10.10.254.
b. H2 and H4 should be given IP addresses in the Users VLAN, with a default gateway of 10.10.20.254.

Task 2: Perform basic connectivity tests

Step 1: Test intra-VLAN connectivity
a. Ping from H1 to H3.
Is the ping successful? __________ Ya
If the ping fails, troubleshoot the configuration on the hosts and the VLAN configuration on the switches.
b. Ping from H2 to H4.
Is the ping successful? __________ Ya
If the ping fails, troubleshoot the configuration on the hosts and the VLAN configuration on the switches.

Step 2: Test inter-VLAN connectivity
Ping from a host on the Servers VLAN to a host on the Users VLAN.
Is the ping successful? __________ Ya
If the ping fails, troubleshoot the router and switch configurations.

Task 3: Introduce link and device failures into the network, and observe results

Step 1: Determine the port status of the spanning tree on the server switch
FC-ASW-1#show span
VLAN0010
Spanning tree enabled protocol ieee
Root ID Priority 32778

Which port is not currently participating in forwarding data? __________ Fa0/4 adalah alternatif

Step 2: Induce a link failure on the server switch
Remove the cable from one of the forwarding ports on FC-ASW-1.

Step 3: View the adjustment to the spanning-tree
Re-issue the show span command.
How long did it take the switches to determine and utilize a backup link? __________

Step 4: Induce a device failure on the network
Turn off the ProductionSW switch.
Ping from H1 to H2.
Was the ping successful? __________ Yes, both hosts are on the FC-ASW-1 switch and inter-VLAN
routing is still taking place.

Step 5: Reflect on the test results
In a network with multiple branch offices, why is the use of Rapid Spanning Tree Protocol important?
RSTP adalah penting untuk memastikan konektivitas perangkat pada layer akses di setiap kantor cabang dan bahwa sumber daya seperti server yang dapat diakses oleh pengguna di kantor-kantor lain yang bergantung pada mereka, dalam hal terjadi kegagalan switch-terkait setempat.

Why is it important when implementing a server farm?
RSTP akan membantu untuk memastikan bahwa switch dapat sembuh dengan cepat dan menyimpan server diakses oleh pengguna dalam hal link, switch atau kegagalan port.
