2.5 BPDU Tunneling Configuration Example
I. Network requirements
z Customer A, Customer B, Customer C, and Customer D are customer network
access devices.
z Provider A, Provider B, and Provider C are service provider network access
devices, which are interconnected through configured trunk ports.
The configuration is required to satisfy the following requirements:
z Geographically dispersed customer networks Customer A, Customer C and
Customer D can implement consistent spanning tree calculation across the
service provider network.
z BPDU packets are isolated for the customer network Customer B, so it does not
take part in the spanning tree calculation.
