Bind two network cards, share one IP, realize the redundancy effect. In fact, there are 7 types of bindings for Linux dual NICs: The mode=0 indicates that load balancing (round-robin) is balanced, and both NICs work. mode=1 says Fault-tolerance (active-backup) provides redundancy, working in a master-slave way, which means that only one NIC works by default, and the other is backed up. Mode

A: Principle: There are seven modes for dual NIC bindings under Linux operating system. Now the general enterprise will use dual-card access, so that both the network bandwidth can be added, while the corresponding redundancy can be said to be a lot of benefits. And the general enterprise will use the Linux operating system comes with the network card binding mod

Objective: To improve the speed of Samba file sharing with the Virtual Machine Ubuntu. Solution: Ubuntu uses a dual-nic. One bridge is connected to the physical Nic, And the other uses the host-only method to interact with the host for Samba. As shown in: After a virtual network card with host-only access is added, the virtual machine can actually access the Samb

To improve the high availability of the system, we can bind two or more NICs to a virtual Nic and use the same IP address to ensure that a link is disconnected, another link can be started at any time to improve system stability.
