How do routing paths and subnets work?
Networks in the internet are connected to each other via routers. Routers carry traffic from one network/subnet to another. Routers maintain a routing table to decide how to route the IP packets. Each routing entry consists of the destination address, subnet mask and “route to” field.
Can different VLANs communicate?
Devices in different VLANs cannot communicate when only using layer 2 switches. In other words, a layer 2 switch allows devices in the same VLAN or subnet to communicate. Any VLAN to VLAN communication will not be allowed with just a layer 2 switch.
How do you communicate between subnets?
Computers located on different subnets may need to communicate directly with one another….How to Connect Computers That Are on 2 Different Subnets
- Connect the computers to the network.
- Connect the routers to each other.
- Enable a routing protocol in each subnet’s router.
- Allow time for the routing tables to update.
How to make Linux routing between multiple subnets persistent?
On the non-routing boxes with only one interface, set the default route to point to 10.0.x.1. Of course you will also have to add the static addresses and netmasks on all the interfaces. The ip commands above do not make the settings persistent, how to do that is dependent on the distribution.
How to add static routes to another network?
You will need to add static routes to the other 10.0.x.0/24 networks on each router box, with commands something like this (EDITED!): and the corresponding routes on the other router boxes. On the non-routing boxes with only one interface, set the default route to point to 10.0.x.1.
