Default Router

Vivek_3 — Tue, 07 Aug 2001 22:54:02 GMT

Hi,

I have confusion regarding default router or dynamic routing. I have defined a default router entry in /etc/rc.config.d/netconf file. But when I rebooted my system I found that I have lost my network connectivity with other system.

So when I was trying to find some reason I found followings suspicious things:

I don?t ( netstat ?rn) have default router entry in my routing table even though my /etc/rc.config.d/netconf file has a entry for default router.

Second thing I found that in my /etc/rc.config.d/netconf file dynamic routing was set to on (GATED=1). I am not using dynamic routing.

Does it create any problem with default router? Because everything is fine after I added default entry to my router table.

I need to find out cause of the problem, so please do reply.

Thanks
vivek

Hi Vivek,

First thing, Since Dynamic Routing is not being used, you can comment GATED value or make it 0 in netconf file.

After doing so, still if the gateway problem continues, check for the Route Count value in the netconf file. It should be set to 1.

For me whenever I was rebooting the server, the default gateway was missing. Later we found that there was multiple entry of Route Count mentioned 1 as well as 0 in the last line of the file.

So check for the proper Route Count value in
the netconf file.

Hope this would help you.

Hello,
In the netconf file modify the entries.
change your GATED value to 0.
Enter your gateway ipaddress.
Change ROUTE_COUNT to 1.
ROUTE_GATEWAY[0]=xx.xx.xx.xx
ROUTE_COUNT[0]=1
ROUTE_DESTINATION[0]="default" .
Then do a reboot.
OR

If you want to add the route entry on the fly
Then,
#route add net default xx.xx.xx.xx 1

OR

Even you can use
#set_parms addl_netwrk to configure your gateway.

Thanks

Hi

As you seem to have lost the network connectibity after reboot it will help to check the /etc/rc.log to check if network startup scripts were executed without errors.

Hi,
#set_parms initial
once you set all the values including the gateway, your default gateway will remain unchanged

a count of 1 should be used when the gateway is a separate system. if you are using your own local IP address as the default route (aka proxy arp), the count should be 0
