Yes, in a WISP (Wireless Internet Service Provider) implementation, it is entirely feasible to establish routes between all MikroTik routers on each node of the network.

This is commonly done to improve network management, optimize traffic routing, and increase system redundancy and resiliency.

Here's an overview of how you can configure routes between MikroTik routers on a WISP network:

1. Network Planning

Before starting, it is important to design a network topology that defines how all the nodes (MikroTik routers) will be connected. This may include mesh, ring, star topologies, or a combination of these, depending on redundancy requirements and geographic reach.

2. Interconnection Configuration

MikroTik routers can be interconnected using wireless or wired links. In a WISP scenario, wireless links are common to connect distant nodes.

Make sure each link is assigned a unique network IP to avoid conflicts and make routing management easier.

3. Static or Dynamic Routing

You can choose to use static or dynamic routing:

• Static Routing: Manually define the routes on each router. This may be simple on smaller networks but becomes complicated as the network grows.
• Dynamic Routing: Uses dynamic routing protocols such as OSPF (Open Shortest Path First) or BGP (Border Gateway Protocol). OSPF is ideal for internal networks while BGP is commonly used for exchanging routes between different autonomous systems.

4. OSPF implementation

For a WISP network using MikroTik routers, OSPF is an excellent choice because it is relatively easy to configure and handles alterations to the network topology well. Here's how you could set it up:

• Configure the Interfaces: Make sure that each interface that will participate in OSPF has an appropriate IP address.
• Enable OSPF on Routers: Configures OSPF on each router and defines the areas and interfaces that will participate.

/routing ospf instance
set [ find default=yes ] redistribute-connected=as-type-1
/routing ospf area
add area-id=0.0.0.0 name=backbone
/routing ospf network
add area=backbone network=192.168.88.0/24

• Monitor and Optimize- Use MikroTik tools to monitor OSPF status and adjust configurations as necessary.

5. Network Security

Don't forget to implement appropriate security measures to protect the routers and the network. This includes the use of firewalls, access lists, and encryption of wireless links.

6. Maintenance and Continuous Monitoring

Managing a WISP network involves continually monitoring network performance and adjusting configurations to optimize service. Use tools built into MikroTik and external network monitoring solutions to help with this task.

Implementing routes between all MikroTik routers in a WISP network using these strategies will help ensure a robust and efficient network, capable of adapting to changing user needs and network conditions.
