BPDU tunneling for PVST configuration example
Network requirements
As shown in Figure 30:
 CE 1 and CE 2 are edge devices on the geographically dispersed network of User A. 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.
