Customer has requested to add the following route on xyz houst:

Route to                     System            add/delete     Netmask                     Gateway

195.233.141.105         xyz         add                  255.255.255.255         195.233.141.1    

xyz:/root#netstat -nr|grep 195.233.141.105

While Adding the route, I am getting the following error:

anldeabh:/root#route add host 195.233.141.105 195.233.141.1 1
add host 195.233.141.105: gateway 195.233.141.1: entry in use

Please suggest where is the mistake

Look at the first line of your netstat output.  The host 195.233.141.105 is already there. 

195.233.141.105       195.233.141.105    UH        0  lan5       4136

This probably needs to be removed before you try to add it again.

Hi Patrick

Would there be any issue in removing the route:

195.233.141.105       195.233.141.105    UH        0  lan5       4136

Is 195.233.141.105 the IP address of the local host?  If so, you don't really need a route  to 195.233.141.1 to get to it.

[Indrajit Bhagat]

Hi Patrick

The Ip address 195.233.141.105  belongs to lan5

anldeabh:/etc#  ifconfig lan5
lan5: flags=1843<UP,BROADCAST,RUNNING,MULTICAST,CKO>
        inet 195.233.141.105 netmask ffffff00 broadcast 195.233.141.255

Also I tried to delete this route, but not able to delete it

anldeabh:/etc#route delete 195.233.141.105 195.233.141.105
delete host 195.233.141.105: gateway 195.233.141.105: no such route
anldeabh:/etc#route delete host 195.233.141.105 netmask 255.255.255.255 195.233.141.105
netmask: bad value
anldeabh:/etc#route delete net 195.233.141.105 netmask 255.255.255.255 195.233.141.105
delete net 195.233.141.105: gateway 195.233.141.105: no such route

OK, I am now confused.  What exactly are you trying to accomplish?

You said:

Customer has requested to add the following route on xyz houst:

Route to          System     add/delete     Netmask                  Gateway

195.233.141.105     xyz         add         255.255.255.255         195.233.141.1

If 195.233.141.105 is on lan5, why do you need to get to it via 195.233.141.1?
