Task 1.4 - Why change the system mtu on the customer switch?
For this task we're required to create a dot1q tunnel between fa0/5 on SW1 and fa0/17 on SW4. SW2's fa0/20 is the customer port connecting to fa0/17 on SW4. So why does the SG configure SW2 (the customer switch) with an increased mtu?
Isn't the metro-tag removed by SW4 prior to sending the frame to SW2?
Also, in a previous mock lab I was penalised for not configuring 'vlan dot1q tag native' on the service provider switches, but the SG doesn't configure 'vlan dot1q tag native' for this task. Isn't it 'best practise' to implement native vlan tagging on the service provider switches?
