13.7 Technical Reference
This section provides technical background information on the topics discussed in this chapter.
13.7.1 MSTP Network Example
The following figure shows a network example where two VLANs are configured on the two
switches. If the switches are using STP or RSTP, the link for VLAN 2 will be blocked as STP and RSTP
allow only one link in the network and block the redundant link.
Figure 96
STP/RSTP Network Example
With MSTP, VLANs 1 and 2 are mapped to different spanning trees in the network. Thus traffic from
the two VLANs travel on different paths. The following figure shows the network example using
MSTP.
Designated Port
ID
This field displays the priority and number of the bridge port (on the designated bridge),
through which the designated bridge transmits the stored configuration messages.
Designated Cost
This field displays the path cost to the LAN segment to which the port is connected when
the port is a designated port. Otherwise, it displays the path cost to the root bridge from
the designated port for the LAN segament to which this port is connected.
