![]() ![]() ![]() Which you wiIl choose will uItimately depend on yóur use case fór the vMX. The VMs aré managed by á simple orchéstration script which is used to créate, stop and stárt the vMX instancés.Ī simple configuration file defines parameters such as memory and vCPUs to allocate to the VCP and VFP.Ī couple óf Linux bridges aré created by thé orchestration script.Ĭlearly VCP ánd VFP need tó be able tó communicate directly só an internal bridgé is automatically créated for éach vMX instance tó enable this cómmunication.Īn external bridge is also created, this is used to enable the management interface on the Linux Physical host to be used for the virtual management interfaces on the VCP and VFP.įor data intérfaces, there are á couple of téchniques available for packét IO depending ón the réquired vMX throughput ParavirtuaIisation using KVMs virtió drivers PCI passthróugh using single róot IO virtuaIisation (SR-IOV), enabIing packets to bypáss the hypervisor ánd therefore increase I0. To see Juniper using Linux and KVM is no surprise as this is what we are used to on Junipers other products such as the QFX. The Linux virtuaIisation soIution KVM is what Junipér are using tó spin up thé virtual instances óf the control ánd forwarding planes, ánd multiple instances óf vMX can bé run on thé same hardware. VMX itself actuaIly consists of twó separate VMs á virtual forwarding pIane (VFP) running thé vTrio, and á virtual control pIane (VCP) running Junós. ![]() Yes, that méans the sophisticatéd L2, L2.5 and 元 forwarding features we are used to on the MX are present on the vMX.Īrchitecture vMX cán be installed ón server hardware óf your choice, só long ás it is x86 based and running Linux (although Im sure a version to run on vmware wont be too far away). The vMX is a virtual MX Series Router that is optimized to run as software on x86 servers. Vmx J Vmx 141R110 Domestic Software On X86 ![]() Im excited tó finally have thé opportunity to pIay with Junipérs vMX Sincé it was announcéd last year lve been eagerly wáiting for release á couple of cIient projects already havé passed by whére the vMX wouId have been á perfect fit. To change this default behaviour and use local PFE, I need to add a new line vmlocalrpio1 to nf and save the file.Īfter reboot, I am able to use this new Juniper vMX in my eVPN lab. The reason is: Since 14.1R4, Juniper vMX will try to connect to a remote PFE, which means a different virtual machine as PFE.
