What are the differences between network bridges and VLANs

14

Network bridges can implement packet forwarding at Layer 2 on the wide area network (WAN) side. Only Layer 2 interfaces can be added to virtual local area networks (VLANs). Only Layer 3 interfaces can be added to network bridges.

What are the differences between network bridge MAC addresses and common MAC addresses
The two types of MAC addresses have the same functions. Packets bridged by network bridges are complete Ethernet Layer 2 packets.

Differences between GVRP VLAN and VCMP VLAN
VLAN Central Management Protocol (VCMP) is located at the Layer 2 of OSI model. It propagates VLAN information within a Layer 2 network and ensures VLAN information consistency on the Layer 2 network. The GARP VLAN Registration Protocol (GVRP) is used to register and deregister VLAN attributes. The Generic Attribute Registration Protocol (GARP) provides a mechanism to propagate attributes so that a protocol entity can register and deregister attributes. GARP transmits attributes. The VLANs on S series switches, except S1700 and S9300 are as follows: 1. GVRP creates dynamic VLANs, whereas VCMP creates static VLANs. When you run the display vlan summary command, the VLAN of GVRP displays Dynamic vlan and the VLAN of VCMP displays Static vlan. 2. VCMP can only help network administrators synchronize VLAN configurations, but cannot dynamically add interfaces to VLANs. GVRP can simplify VLAN configuration and is able to dynamically add interfaces to VLANs.

What is the difference between the BPDU packet transparent transmission modes of the bridges on AR routers in different forms

Difference between the BPDU packet transparent transmission modes of the bridges on AR routers in different forms:
The bridges on AR routers in all forms do not transparently transmit BPDU packets. Therefore, there is no difference.

What are the differences between the MAC address of a bridge on an AR router and a normal MAC address
The MAC address of a bridge on an AR router equals to a normal MAC address. A bridge bridges complete Layer-2 Ethernet packets.
