Configuration Of Multiple Spanning Tree Protocol Interface Setting With Dual Lan - ICP DAS USA LP-22 Series User Manual

7.2. Configuration of multiple spanning tree protocol interface
setting with dual LAN
The LP-22xx/8x2x/9x2x series modules include support for the MSTPD daemon, which is the
Spanning Tree Protocol (STP) that is always recommended in layer 2 topologies that run on
bridges and switches. An extension of STP is the MSTP (Multiple Spanning Tree Protocol), which
can be used to prevent loops and broadcast storms on a network, and also provide redundant
links for automatic failover if an active link fails. The bridge function allows a virtual interface to
be configured so that it can be included in the network. The virtual interface behaves similarly to a
physical interface and ensures that LinPAC networking communication is always active, as
illustrated in Figure 7.2-1.
