No Agreement Check configuration example
1) Network requirements
As shown in Figure 1-11 ,
z
Device A connects to Device B, a third-party device that has different MSTP implementation. Both
devices are in the same region.
z
Device B is the regional root bridge, and Device A is the downstream device.

Configuring Protection Functions
An MSTP-enabled device supports the following protection functions:
z
BPDU guard
z
Root guard
z
Loop guard
z
TC-BPDU guard
Configuration prerequisites
MSTP has been correctly configured on the device.
Enabling BPDU guard
