EVPN lab – EVPN-VXLAN to EVPN-MPLS stitching

EVPN lab – EVPN-VXLAN to EVPN-MPLS stitching

Last big topic that I need to practice – Data Center Interconnect (DCI). Fortunately I pretty confident in my skills in the MPLS L3VPN area, so I think I shouldn’t spend much time for this topic. The most complex DCI option remains – EVPN stitching. In this topic I will show you my example of EVPN-VXLAN to EVPN-MPLS stitching (there is also option of EVPN-VXLAN to EVPN-VXLAN stitching, but configuration should be similar to my example). EVPN stitching concept is…

EVPN-VXLAN to EVPN-MPLS stitching

For full configuration eample of EVPN-VXLAN to EVPN-MPLS stitching refer to MX Layer 2 VPNs Feature Guide, Chapter 28. First of all, you need to configure Logical Tunnel (lt-) interface for traffic between EVPN-VXLAN and EVPN-MPLS instances: interfaces lt-1/0/10 {     esi {         36:36:36:36:36:36:36:36:36:36;         all-active;     }     unit 3 {         encapsulation ethernet-bridge;         peer-unit 4;         family bridge {    …

DCI options for EVPN

Four Data Center InterConnect (DCI) options for EVPN-VXLAN service are described in detail in the Advanced Data Center Switching (ADCX) course materials. These options are: EVPN-VXLAN session over L3VPN-MPLS service; EVPN-VXLAN to EVPN-MPLS stitching; EVPN-VXLAN to EVPN-VXLAN stitching; EVPN-VXLAN session over dark fiber. First and last options are not so interesting – simple EVPN-VXLAN session between DC devices over direct IP connectivity or via L3VPN service. Basic L3VPN/MPLS stuff. But EVPN stitching is a slightly different story. Resembles Inter-AS VRF Option-A….
