DCI was always a challenge in days of VPLS and other vendor specific layer 2 extension technologies. Main challenge was how and where to integrate layer 2 and layer 3 e.g VPLS does offer layer 2 extension between 2 DCs but main challenge was where to configure layer 3 gateways and how to maintain ARP entry for gateway inside a Virtual Machine (VM) if VM moves from once DC to another DC.
EVPN gives answer to all those questions as we can create MAC-VRF along with Integrated Routing and Bridging (IRB) interface for a VLAN and that IRB interface can also be referred under standard L3 VRF if L3 extension is required between DCs. Thus, EVPN allows to combines L2 and L3 at L3 VTEP layer. Furthermore, we can configure same “virtual-gateway” on all L3 VTEPs for a VLAN. This scenario will allow a VM to maintain the ARP entry for the gateways if it moves from one DC to another DC.
In each Data Center “Collapsed IP CLOS” is recommended to be configured if DCI Option 1 is selected for Layer 2 extension between the DCs. Continue reading
