The path cost from AP1 to CP2 is 9 and that from AP2 to CP1 is 10. Therefore, CP2 is the
root port and BP2 is the designated port.
6.14 RSTP/STP Transparent Transmission
6.14.1 Overview
RSTP is compliant with IEEE standard. DT-Ring is the private redundant protection protocol
of Kyland, but cannot coexist with RSTP on the same network. To solve this problem, Kyland
developed the RSTP/STP transparent transmission function. The function enables the
switch to keep other redundant protocols while transparently transmitting RSTP packets,
meeting industrial communication requirements.
Switches running other redundant protocols can receive and forward RSTP packets only if
the
RSTP
transparent
transmission
function
is
enabled.
RSTP
transparent
transmission-enabled switches can be regarded as a transparent link.
As shown in the following figure, Switch A, Switch B, Switch C, and Switch D form a DT ring.
The transparent transmission function is enabled on these four switches, so that Switch E
and Switch F can receive RSTP packets from each other.
