To accomplish this task, first re-configure 3550 and 3750 ports that are facing CE8 and CE1 to accept CEs’ VLANs in the QinQ mode and transport them in the newly allocated service provider VLAN. To allow packets of 1500 bytes to be transported between 3550 and 3750-M, you will need to increase the system MTU to accommodate those extra 8 bytes: 4 dot1Q bytes and 4 bytes for the second label. Because MTU changes on a switch cannot be made per interface, the system MTU change will affect the entire core. When dot1Q tunnelling is enabled, the switches automatically disable CDP and VTP tunnelling for the interfaces facing the CEs. Our goal is to enable CDP and VTP tunnelling, so that CE1 and CE8 appear directly connected to one another. Additional commands will need to be configured to accommodate this requirement.
