The general route target configured under vrf-target will be used by type 1 EVPN routes: MX:   set routing-instances VS_VLAN100 vrf-target target:1:100 QFX:  set switch-options vrf-target target:65000:2 If you configure vrf-target auto, then type 2 and type 3 EVPN routes will use the auto-derived per-VNI route target for export and import. Community numbers based on autonomous system number defined in routing-options stanza. MX:   set routing-instances VS_VLAN100 switch-options vrf-target auto QFX:  set switch-options vrf-target auto If you prefer…

The overall structure of QFX5100 EVPN-VXLAN configuration is almost identical to MX configuration, but QFX configuration statements are scattered across three different stanzas: switch-options, protocols evpn and vlans. First is the switch-options config: set switch-options vtep-source-interface lo0.0 set switch-options route-distinguisher 10.0.0.3:1 set switch-options vrf-import EVPN_VRF_IMPORT set switch-options vrf-target target:65000:2 set switch-options vrf-target auto           ### depends on AS number in routing-options Vtep-source-interface and route-target policices are configured here. Configuration of vrf-import policy: set policy-options…

For study of Juniper EVPN technology I recommend to read this materials (in this particular order): Juniper QFX10000 Series book; EVPN whitepaper; Advanced Data Center Switching (ADCX) course materials; EVPN Day One book; L3GW VMTO whitepaper; MX L2VPN Feature Guide; QFX EVPN/VXLAN Feature Guide. EVPN is definitely the core topic of JNCIE-DC lab, so I need to study all of this thoroughly. Firstly I need to read (and understand) all this stuff, and later on I plan to heavily practice all…

VXLAN Multicast

VXLAN Multicast

Comments 0 Comment

VXLAN with Multicast control plane is not explicitly stated in JNCIE-DC lab exam topics, so I not expect it on the exam. But anyway I decided to start Overlay topics from the simple case and later on continue to more advanced ones. Firstly, for Multicast VXLAN of course you need to configure Multicast protocol in the Underlay. Nothing complex, just basic PIM stuff: configure PIM interfaces and some kind of RP (static/local/anycast-RP). Configure VTEP source interface: set switch-options vtep-source-interface lo0.0 …

In this post I tried to collect all useful links to technical documentation that I plan to use during my study for JNCIE-DC lab attempt. This materials will be used primarily for repetition and more focused, deep-dive study of lab topics – should be used only after studying Juniper DC base materials from previous post. So, the complete JNCIE-DC exam blueprint: Management On-box Scripts                               –>…
