AIX

Hello guys.

I have a AIX running an ip of 128.2.1.85 255.255.255.0, Main office router is 128.2.1.2 .we just got an t1 line point to point for a remote office with to pcs.

My question.

I'm not able to ping those pcs one of them is using this ip 128.2.2.128 255.255.255.0 Remote router ip is 128.2.2.2
We have an NT server using this routing entry route -t -p add 128.2.2.0 mask 255.255.255.0 128.2.1.2 and it works just fine.

I know that there is got to be a command like route add net but i dont know how to doit .
I any of you guys can give me a hando on these i will really apreciate it.

Thanks a lot guys.

route (add/delete) (-net/-host) (destination) (gateway)
Adds or deletes routes to other networks or hosts, does not update
the ODM database and will be lost at reboot.

I think your problem is not the routing of AIX but a misconfiguration of the routers. Your network layout looks like:

Code:

Your location                                    remote location
=============                                    ===============
Several machines                                 several machines
in net 128.2.1/24                                in net 128.2.2/24

85 = your AIX box         [a T1 line]            128 = a PC
2  = your router   <------------------------->   2   = another router

Usually it is the job of the routers (not the servers) to know how to relay packets from one network to another, therefore the machines (regardless of being servers or clients) should have only three entries in their routing table:

1. a loopback route

2. a net route for their own net pointing to their own interface. In case of your AIX box this would be "route add -net 128.2.1 -netmask 255.255.255.0 128.2.1.85". As this route would be lost upon reboot use SMIT to insert it in a lasting way. You can find the panel by typing "smitty tcpip" on the commandline, then select further "configuration/static routes".

3. a default route[/b], pointing to their nearest router. This would be 128.2.1.2 for all machines in your location and 128.2.2.2 for all machines in the remote location. Use SMIT to add the default route by issuing "smitty tcpip" at the commandline, then select "minimum configuration" and your interface, presumably "en0". In the upcoming screen there will be the option "default route".

This procedure will be the same for any machine on your network, regardless of being server or client, Windoze or *NIX machine.

The routing between the networks should be handled by the router (after all, that's his genuine job). Consult your routers manual on how to do this. The principle is the same as with the servers: you basically tell the machine to send al packets with destination net A to this interface, all packets with destination B to that interface and usually add a "default" route as a last resort - it means "if there's no explicit rule where to send the packet then send it there and hope for the best".

Hope this helps
