PE 1 and PE 2 are edge devices on the service provider network. • All ports that connect service provider devices and customer devices and those that interconnect service provider devices are trunk ports and allow packets of any VLAN to pass through. • PVST is enabled for VLANs 1 through 4094 on User A's network. After the configuration, CE 1 and CE 2 must implement consistent PVST calculation across the service provider network, and the destination multicast MAC address carried in BPDUs must be 0x0100-0CCD-CDD0.
