Note: The performance of these two scenarios is almost the same when guests communicate between Hosts/Servers. Administrators can set up distinct subnets on virtualization servers more easily and efficiently. The topology appears simpler and easier to manage. We don't need to create multiple VLANs and bridges anymore. With the VLAN filter, the Linux bridge acts more like a real switch now.
HOW TO ENABLE MAC FILTERING USING VLAN UPDATE
When creating a bond, VLAN, and bridge interfaces, we can use nmcli or update ifcfg files to make the configuration permanent.

# ip link add link bond0 name bond0.2 type vlan id 2 We need to create more VLANs if dictated by requirements. # ip link set bond0 type bond miimon 100 mode balance-alb Previously, if we wanted to use distinct subnets with guests on a virtualization server, we need to create multiple VLANs and bridges. Let's take an example that is widely used in virtualization: different subnets on a bridge with bond load balance. This feature was introduced in Linux kernel 3.8 and was added to RHEL in version 7.0. In this blog, we will show the new bridge feature, VLAN filter, which hopefully makes life easier. These two important features used to be considered as two completely distinct features and we needed to configure complex topologies to combine them together. Also, it can separate hosts/guests under the same switch/bridge into different subnets. This can greatly simplify network design and deployment. It allows network administrators to group hosts together even if the hosts are not on the same physical network switch.

VLAN is another very important function in virtualization. The Linux bridge is actually a virtual switch and widely used with KVM/QEMU hypervisor, namespaces, etc. Since forwarding is done at Layer 2, all protocols can go transparently through the bridge. Packets are forwarded based on Ethernet address, rather than IP address (as a router would do). But behind them, there are two indispensable features: Bridge and VLAN.Ī bridge is a way to connect two Ethernet segments together in a protocol independent way. These technologies are getting increasingly important and popular. Virtualization, Cloud, OpenStack, and Docker. With only ONE bridge, you can control all VLANs. With the VLAN filter, people don't need to create dozens of VLANs and bridges anymore. On a VLAN, clear the MAC address forwarding table entries for that VLAN.This blog aims for Administrators who need to handle large numbers of VLANs in virtualization/namespaces with a bridge. To change the limit onĪll interfaces and VLANs, clear all MAC address forwarding table entries. Thus, to change the limit on an interface, firstĬlear the MAC address forwarding table entries for that interface. Or a VLAN, you must first clear existing entries in the MAC address forwarding table thatĬorrespond to the change you want to make.
