Functions of a virtual bridge

4

The concept of a virtual bridge (VB) was innovatively put forward by Huawei. The switching domain of an Ethernet board that has Layer 2 switching capabilities can be divided into multiple sub-switching domains. If no services are interconnected, different VBs cannot gain access to each other. Each VB has an independent configuration mode and uses an independent VLAN. Different VBs can use the same VLAN.

Can the MAC address of the bridged virtual interface of a bridge on an AR router be modified

The MAC address of the bridged virtual interface (BVI) of a bridge on an AR router can be modified.
You can run the mac-address command in the Bridge-if interface view to modify the MAC address of the current bridged virtual interface.
The MAC address of a bridged virtual interface is the system MAC address, which may conflict with the MAC addresses of other interfaces or virtual interfaces. If the MAC address of a bridged virtual interface conflicts with the MAC addresses of member interfaces of the bridge group, the bridged virtual interface cannot transmit traffic in Layer 3.
When configuring a bridged virtual interface, confirm whether the MAC address of the interface conflicts with the MAC addresses of the member interfaces of the bridge group. If the MAC addresses conflict, you can run the mac-address command to modify the MAC address of the Bridge-if interface.
After the MAC address of the bridged virtual interface is modified, the device proactively sends a free ARP to update the ARP entries on the peer device.

What are the differences between a bridge on an AR router and a VLAN
A bridge on an AR router can forward WAN packets in Layer 2. In addition, Layer-3 interfaces can be added into a bridge, which is different from a VLAN into which only Layer-2 interfaces can be added.

Ivy Bridge
Ivy Bridge (IVB) is the third-generation Core i series CPU launched by Intel in 2012. Compared with Sandy Bridge, Ivy Bridge uses 22 nm and 3D transistor technologies to improve the transistor density greatly and performance of core graphics cards by over one fold. Huawei RH2288H V2 and RH1288 V2 servers support Ivy Bridge CPUs.
