Question

Configuring Winodws XP Routing Tables

Asked by: adimit

I have multiple multi-homed PC`s running windows XP, eah with three netwrok cards. Each NIC is connected to a unique sqitch.

Each switch connets to a unique data source. The application is configured to know the IP addresses of the data source.

I want to make sure that information is routed correctly. I don`t have nwtork addresses yet, but lets say that the following represents my network addresses:
Network adapter 1 (10 MB)
IP address: 10.0.0.169
Subnet mask: 255.0.0.0

Network adapter 2 (100 MB)

IP address: 192.168.0.200
Subnet mask: 255.255.0.0


Network adapter 2 (100 MB)
IP address: 172.168.0.50
Subnet mask: 255.255.255.0

I also have a domain controller on network 2

What should my default gateway be.

In my routing table if I see the same netmask for different network destinations, is that an indication that packets could go in different routes.

Dows my cisco switch at as a gateway

is ther esomething i need to do on the switch to facilitate routing

I have read several articles including the following

--> What should my default gateway be.

We can't tell you that.  You need to known this.  Which router will get you to remote hosts if you don't have a specific route to them.  Normally this is the router that either gets you to the Internet, or has the shortest path to get you to the Internet.

--> Dows my cisco switch at as a gateway

It depends.  If it is a L3 switch, then yes it COULD act as a gateway/router if configured to do so.

In order to route between different subnets or LANs you need a router or a Layer 3 switch. there are also software routers but their performance lack behind hardware routing devices. for each subnet you have to configure the default gateway for that subnet, which must be an ip address on the same range. if you are going to use a router, in case your switches do not support Layer 3, you need to configure this router with interfaces or subinterfaces on all subnets/LANs. You can find plenty of material on the Cisco site on how to configure Cisco gear.

Windows can only accept one default gateway. It accepts the gateway for the default NIC.  In that case then would I need a router?

 

by: giltjrPosted on 2009-09-01 at 08:04:58ID: 25232306

You only need a router if you plan to talk to IP addresses that are NOT within your IP subnet.

Just as a F.Y.I., a gateway and a router are really the same thing.

The default gateway is the router your computer will use if it does not have a specific route for the host/subnet you are trying to get to.
