SunOS: Route delete problem

If you ever encouter problem deleting routing in SunOS, make sure you specify the netmask.

For example:
1. add routing:
root@xyz # route add -net 123.45.57.0 34.56.78.1 -netmask 255.255.255.192

2. out of no reason, you want to delete routing that u just add:
root@xyz # route delete -net 123.45.57.0 34.56.78.1
delete net 123.45.57.0: gateway 34.56.78.1: not in table
root@xyz #

you will received error msg as above.

So, what you need to do is to specify the netmask, such as:
root@xyz # route delete -net 123.45.57.0/26 34.56.78.1

* to check netmask for the specific entry, use command: root@xyz # netstat -rvn
Voila!
