4.7 Combination of RSTP
and MRP
In the MRP compatibility mode, the device allows you to combine RSTP with
MRP.
With the combination of RSTP and MRP, the fast switching times of MRP are
maintained.
The RSTP diameter
(see fig. 38) depends on the “Max Age”. It applies to the
devices outside the MRP-Ring.
Note: The combination of RSTP and MRP requires the root bridge and the
backup root bridge to be within the MRP-Ring.
