how to modify routing table

Mauro Gatti — Mon, 23 Sep 2002 14:59:59 GMT

Hi all, this is my netstat -rnv output:

gemini# netstat -rnv
Routing tables
Dest/Netmask Gateway Flags Refs Interface Pmtu
127.0.0.1/255.255.255.255 127.0.0.1 UH 0 lo0 4136
194.63.1.31/255.255.255.255 194.63.1.31 UH 0 lan0 4136
194.63.0.0/255.255.0.0 194.63.1.31 U 2 lan0 1500
127.0.0.0/255.0.0.0 127.0.0.1 U 0 lo0 0
default/0.0.0.0 194.63.131.20 UG 0 lan0 0

I'd like to remove 2nd rule
but "route delete 194.63.1.31 netmask 255.255.255.255 194.63.1.31" returns:

usage: delete destination [netmask mask] gateway

how could i remove it?

Thank you

Looks like it was added in using the route add host option (flags UH) so try route delete host ... to remove it.

Try

route delete 194.63.1.31 194.63.1.31

If you get error , route not in table, try

route delete net 194.63.1.31 194.63.1.31

ps

It does look as though the entry is incorrect though as I would expect to see a route to a network via a gateway. In your example you have a route to a network via the same address as the gateway

Hi,

???...

Why do you want to delete this route?.

You can try not using netmask and mask parameters. It is a host entry.

gemini# route delete 194.63.1.31 194.63.1.31
delete host 194.63.1.31: gateway 194.63.1.31: no such route

route delete net 194.63.1.31 194.63.1.31 delete rule 3!

gemini# route delete host 194.63.1.31 netmask 255.255.255.255 194.63.1.31
usage: delete destination [netmask mask] gateway

I'd like to have a final situation like:

Routing tables
Dest/Netmask Gateway Flags Refs Interface Pmtu
127.0.0.1/255.255.255.255 127.0.0.1 UH 0 lo0 4136
194.63.0.0/255.255.0.0 194.63.1.71 U 2 lan0 1500
127.0.0.0/255.0.0.0 127.0.0.1 U 0 lo0 0
default/0.0.0.0 194.63.131.20 UG 0 lan0 0

Hi (again),

As I mentioned before, it is a host route internal to the system and I am not positive if we can delete it.

Mauro,

I am sure you can delete that route. But what i would like to question alongwith with Sri, is that why are u deleting your system route.

That route pertains to your network interface.

Also, why are you keeping the other routes without your primary network route.

Anil
