actionpaster.blogg.se - Vyos show mac address table

If you have any comments? Please respond below! 🙂 Sources Thanks for reading this blog post and see you next time. Currently, I am running multiple boxes for multi-site just to test VMware NSX-T in my Lab environment. The next step will be to connect with my lab environment and leveraging BGP. This is just the first of testing the VRF. There are a lot of use cases think about multiple routers with different routing protocols running on a single VyOS box with there own routing table.įor me, this was an easy step to test the VRF feature with the Out-of-Band management test. The VRF feature that is added to VyOS is really great! It is a great addition to an already great product.

Monitoring server that monitors with SNMP = 192.168.200.100.

Gateway of the Out-of-Band Management network = 192.168.200.254.

VyOS IP Address for Out-of-Band Management = 192.168.200.1.

Here is some information about my IP numbers: Set service snmp listen-address 192.168.200.1 port 161 Set service snmp contact SNMP - Activate the listening address Set service snmp location " - Datacenter" Set service snmp community routers client 192.168.200.20 Set service snmp community routers authorization ro Set service ssh listen-address 192.168.200.1 # SSH - Active listing address for SSH on Out-of-Band network SSH is used for access to the command-line of the VyOS router and SNMP is used for monitoring. Now it is up and running it is time to set up the out-of-band management services. As you can see one NIC is connected to a portgroup that allows multiple VLANs and the other is connected to a dedicated network for out-of-band management. Here is an overview of the vSphere VM running VyOS with two virtual network cards connected. One of the perks of having a dedicated interface is to improve security and it makes creating firewall rules easier because all of the out-of-band interfaces are in one dedicated network. The main reason for me was to split the SSH and SNMP traffic from the rest of the traffic. This can only be achieved by the new VRF feature because you get an extra/new routing table that is used by the VRF only. The goal for me was to create an out-of-band management interface on my virtual VyoS router that is running on VMware vSphere. Network functionality is improved because network paths can be segmented without requiring multiple routers.” Goal Because the routing instances are independent, the same or overlapping IP addresses can be used without conflicting with each other. VRFs are the TCP/IP layer 3 equivalent of a VLAN. One or more logical or physical interfaces may have a VRF and these VRFs do not share routes therefore the packets are only forwarded between interfaces on the same VRF. “Virtual routing and forwarding (VRF) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time.

I already talked a little bit about Virtual Routing and Forwarding but here is the official statement from the Wikipedia website:

So after the release of the VRF feature is was time to figure out if it working as I would expect it. The only limit was that VyOS was not capable of running a VRF before. VRF is for a lot of people in network land a known technology and is leveraged in companies all over the world. In this blog post, we are going to set up a VyOS management VRF for out-of-band management traffic. VRF or Virtual Routing and Forwarding is a technology that makes it possible to create multiple routing tables on a single router. In the latest release of VyOS, a new feature has been added to the product called VRF.
