BPDU tunneling for PVST configuration example
Network requirements
As shown in Figure 31 :
• 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 As network.
Configure BPDU tunneling for PVST, so that CE 1 and CE 2 implement consistent PVST calculation across
the service provider network, and the destination multicast MAC address carried in BPDUs is
0x0100-0CCD-CDD0.
