Route Add Help

[Steven Chen_1]

I am add a route other than default route, which is working. I would like to confirm with guru if the setting on netconf is complete:

----------------------
ROUTE_DESTINATION[0]="default"
ROUTE_DESTINATION[1]="10.0.0.0"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="172.16.16.1"
ROUTE_GATEWAY[1]="172.16.16.80"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""
-----------------------
I add ROUTE_DESTINATION[1]="10.0.0.0" and ROUTE_GATEWAY[1]="172.16.16.80".

Is these completed? Any entries on route_count, route_args are needed?

Thank you very much,

Steven

Yes, I believe you should have

ROUTE_COUNT[1]="1"

Other than that everything looks like it should work.

I am concerned about this:

ROUTE_DESTINATION[1]="10.0.0.0"

Its not compatible with the 172 network.

It may work, it just stands out.

For our 10.1 network the default gateway is 10.1.10.1

Hi Steven,

A default gateway will take care of all the routes unless there is a static route for a particular destination. There will be only one default gateway per system.

I believe you are trying to configure a static gateway. It is better if you configure the routes in a modular way. For ex.,


ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="172.16.16.1"
ROUTE_COUNT[0]="1"

The above is the set for default gateway.

ROUTE_DESTINATION[1]="net 10.0.0.0"
ROUTE_MASK[1]=""
ROUTE_GATEWAY[1]="172.16.16.80"
ROUTE_COUNT[1]="1"

Add the word "net" to ROUTE_DESTINATION[1]

The above is the module for the static route to the destination 10.0.0.0. Are you sure you don't want to specify the ROUTE_MASK?. If so, then the default netmask will be taken.

Hi Steven,

First off net routes only need 3 or less octets - like 10.0.0

Second, I assume that 172.16.16.80 is a local IP on this system - correct?

If so then you need a ROUTE_COUNT[1]="0", to denote that the route goes out that NIC.

If NOT, then you need the ROUTE_COUNT[1]="1" - assuming the 172.16.16.80 is a router as well.

But IF your default router is on the same subnet, why do you need a static route? Can't the router handle the route?

Normally static routes are used to get traffic out a secondary NIC other than the NIC that would send to the default router.

Also, personally, I like to keep the route statements separately to make it easiser to see them. Although your way will work.

So I guess you need to tell us just what it is you're trying to do.

Rgds,
Jeff

Thank you all for instant help!

The default route is 172.16.16.1, while 172.16.16.80 is my newly-addition. 172.16.16.80 is a Ethernet port IP of another FW connected to other company using IPSec. 10.0.0.0 is their lan that I route to.

Therefore, the original netconf portion is:

----------------
ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="172.16.16.1"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""
----------------------

New netconf portion is:
******************
ROUTE_DESTINATION[0]="default"
ROUTE_DESTINATION[1]="10.0.0.0"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]="172.16.16.1"
ROUTE_GATEWAY[1]="172.16.16.80"
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""
*******************

I would like to know if I have made any mistake. Some point out I should have "10.0.0", instead of 10.0.0.0. I would like to have someone confirm it also.

Please help further.

Hi Steven,

Your configuration won't work because ROUTE_COUNT[0]="1" is not applicable to your second route. So you will have to have a seperate entry ROUTE_COUNT[1]="1".

Also it doesn't matter if you have the three octets or four octet as 0. Add 'net' to it as I mentioned.

You can also test it by running "/sbin/init.d/net start" command. Once it is run, use the command "netstat -rn" to find out if the route has been added.
