4.2.8 Bridge

A bridge is a functional unit that is used to implement the interconnection between two or more
LANs.
VB and LP
The switching domain of an Ethernet board that has the Layer 2 switching capability can be
divided into multiple sub-switching domains. As a result, if no services are interconnected,
different various bridges (VBs) cannot access each other. Each VB has an independent
configuration mode and uses an independent VLAN. Different VBs can use the same VLAN.
A VB can contain a number of logical ports (LPs). By configuring the mounting relation, you
can mount multiple PORTs and VCTRUNKs to the same VB.

The services of different transparent bridges are isolated , but the services in the same
transparent bridge are not isolated. The entire transparent bridge is a switching domain.
