BPDU tunneling for PVST configuration example

Network requirements
As shown in
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.
