8.3.7 Root 

Guard 

The standard STP does not allow the administrator to enforce the position of the root 
bridge, as any bridge in the network with lower bridge ID will take the role of the root 
bridge. Root guard feature is designed to provide a way to enforce the root bridge place-
ment in the network. Even if the administrator sets the root bridge priority to zero in an ef-
fort to secure the root bridge position, there is still no guarantee against bridge with prior-
ity zero and a lower MAC address.

Root Guard 

 

Software-based bridge applications launched on PCs or other switches connected by a 
customer to a service-provider network can be elected as root switches. If the priority of 
bridge B is zero or any value lower than that of the root bridge, device B will be elected as 
a root bridge for this VLAN. As a result, network topology could be changed. This may 
lead to sub-optimal switching. But, by configuring root guard on switch A, no switches be-
hind the port connecting to switch A can be elected as a root for the service provider

’

s 

switch network. In which case, switch A will block the port connecting switch B. 

To configure Root-Guard, use the following command. 

Command Mode

8.3.8 Restarting 

Protocol Migration 

There are two switches which configured as STP and RSTP. Usually, in this case, STP 
protocol is used between two switches. But if someone configures the STP switch to 
RSTP mode, what happens? Because the RSTP switch already received STP protocol 
packet, the two switches still can work with STP mode even though RSTP is enabled at 
both. If you enable this command, the switch checks STP protocol packet once again.
