BPDU tunneling for PVST configuration example

Network requirements

As shown in

Figure 34

:

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.
