Configuring TC snooping
Figure 21 shows a topology change (TC) snooping application scenario. Device A is an A3100 v2 EI
switch with STP disabled. Device A connects to multiple customer networks, such as Customer 1 and
Customer 2. Device B, Device C, and Device D in customer network Customer 1 are all enabled with STP.
Customer 1 is dual-uplinked to Device A for high availability. Device A transparently transmits STP BPDUs
from Customer 1 at Layer 2. Other customer networks (such as Customer 2) act the same as Customer 1.
