How to set default route for all subnet at once

[j9678]

A router at the center of a star topology. Lets say it has 4 interfaces (different subnet) connected to another 4 routers (non cisco router).

At this time. All I want is just those 5 routers can ping each other.

I don't know this situation should use static or dynamic route. I try both but not work.

Use dynamic route (RIP & OSPF) even not show in "show ip route".

Hi there,

The four spoke routers should have a static default route directing traffic to the hub routers IP address on the subnet they are connected by.

When you start to add more subnets to the spoke routers you will have to add routing entries to the hub router. Depending on your subnet summarisation, at this point you will want to look at a dynamic routing protocol.

cheers,

Seb.

Sorry. I forgot to set default route in those 4 adjacent routers. Case solved
