Lab 8-1: Interface Metrics, Floating Static Routes, and Multiple Equal-Cost Routes (ECMP) Example 8-8 demonstrates the use of different metrics (the least preferable is referred to as a floating static route) for the same prefix as well as equal metrics for load balancing. To access these hosts from the public interface on your router, you must configure port forwarding. Linux allows binding multiple network interfaces into a single channel/NIC using special kernel module called bonding. conf parameters used to restrict Samba to only use particular network interfaces,. Without VLANs, if your network design requires ten machines divided into five different LANs, you would need five different switches or hubs, and most of the ports would be wasted. Each terminal is now connected to a Linux shell on each virtual machine. If your network interface name starts with en, then it's an Ethernet cable directly plugged in.
