we have two datacenters connected with a 1 Gbit fiber connection. I would like to configure a backup connection via the 1 Gbit uplinks. (A second fiber is NOT feasible as one of the DCs do not offer a second physical entry into the building. That means if one fiber is killed by a backhoe, both are killed…) As far as I understand this can be achieved with Vxlan. Unfortunately I simply do not understand the guidelines in http://www.arista.com/assets/data/pdf/Whitepapers/Arista_Design_Guide_DCI_with_VXLAN.pdf
I set up a demo env vie vEOS with two “datacenters” with two arista switches each. They are connected via a virtual linux box playing router.
DC1 / veos1:
interface Ethernet1 description routing / vboxnet3 switchport access vlan 3 ! interface Vlan3 ip address 10.199.0.10/24 ip route 0.0.0.0/0 172.16.0.1
DC2 / veos3:
interface Ethernet1 description routing / vboxnet4 switchport access vlan 4 ! interface Vlan4 ip address 172.16.0.10/24 ip route 0.0.0.0/0 172.16.0.1
eth1: 10.199.0.1/24 eth2: 172.16.0.1/24
How do I set up the tunnel to get a layer 2 connection between these virtual datacenters? Can someone point me into the right direction please?
In the real DCs we have Arista DCS-7050T-52-R with software image version 188.8.131.52
