I've got a weird situation. Three doctors offices are merging in two cities and we are planning on merging them into one building in each city. Due to politics and crappy software each office will run pseudo-independently, meaning we have three networks with their own (overlapping) VLAN's. I'm in charge of networking and our office has the nicest networking gear that will get re-purposed for each building. We're running Arista 7150's with EOS 4.21.1F (and also have 7124SX EOS-4.13.14M) and I plan on getting a 1G carrier ethernet circuit between the two buildings. I would use QinQ, but for whatever reason I have never got QinQ to work over WAN links (works everytime in the lab). I've asked the carrier for more information or to allow QinQ before and gotten nowhere, so I'm going to assume it's not in play. My next thought is to go to VXLAN.
I plan on the following physical design (if I can):
---- Site A (Arista 7150) ---- Site B (Arista 7150) ----
| |
Office 1 (Arista 7124SX) -| |- Office 1 (Arista 7124SX)
Office 2 (Arista 7124SX) -| |- Office 2 (Arista 7124SX)
Office 3 (Arista 7124SX) -| |- Office 3 (Arista 7124SX)
- Can I use QinQ over VXLAN? This would make my life easy as I could assign a SVLAN to each office and be done with it.
- Assuming I can't use QinQ over VXLAN, would I in theory have to manually map each vlan to an SVI? If so, to make my life easier, can I map each office to a range? AKA Office 1 [VLAN 1-4096 - VNI 10000-14096], Office 2 [VLAN 1-4096 - VNI 20000-24096], Office 3 [VLAN 1-4096 - VNI 30000-34096]
I've also put together the following basic config between sites, but it doesn't seem to be working.
## Site A
interface Ethernet1
description Customer Port 1 Site A
switchport access vlan 500
switchport mode dot1q-tunnel
interface Ethernet23
description Site A to Site B link
switchport mode trunk
interface Loopback0
description VXLAN VTEP IP address
ip address 1.1.1.1/32
interface Vxlan1
vxlan source-interface Loopback0
vxlan udp-port 4789
vxlan vlan 500 vni 1500
vxlan flood vtep 2.2.2.2
## Site B
interface Ethernet1
