A possible solution to offloading clients on an existing network

[sajjidkhan67]

I am working with an existing network that services approximately 1500 rural wireless clients [diagram: Customer], and it uses a single core Arista 7050T layer3 switch [diagram: Main Router] hooked up to a 2 Gbit fiber connection. There are multiple wireless backbones in place that deliver layer2 connectivity between that switch and multiple Access Points [diagram: WiFi AP] (Ubiquity Rocket 5AC units) with the backbones being mostly Ubiquity AirFiber 5X units.

Since this would be a fairly big layer2 network, there's routing that is used on the Access Points as well as the core router, where every client is assigned a static IP address and then a route is setup on the core switch via the Access Point they connect to, see diagram below:

Hello @sajjidkhan67 ,

you should realize that there is no Cisco device in your network.

However, if your question is how can I offload traffic from some customers so they go out another internet facing uplink you need to find out the Arista equivalent of Cisco PBR = Policy Based Routing.

we see the customers are getting a direct public IP address that is fixed.

If you had a Cisco switch you would apply PBR on the rx direction of the interface VLAN facing the APs

You could then use an appropriate access-list to match those clients you would like to send to alternate upstream link

access-list 13 remark clients to be treated with PBR

access-list 13 permit host 217.29.53.12

access-list 13 permit host 217.29.53.77

...

route-map PBR-SOME-CLIENTS pemit 10

match address 13

set ip next-hop <upstream -link2-nexthop-ipaddress >

interface vlan 100

desc to APs and users

ip address 192.168.201.1 255.255.255.0

ip policy route-map PBR-SOME-CLIENTS

Hope to help
