Couldn't add route on Solaris 10

UNIX Solaris

Hi Solaris Experts,

I am trying to add a routing table entry on our 5.1 Generic_144488-12 sun4v sparc Solaris 10 SUNW,SPARC-Enterprise-T5220 so that it is possible to ping 10.56.9.34 node

 
# netstat -rnv

# ping 10.56.0.1 (gateway)
10.56.0.1 is alive
# route add -net 10.56.0.0 -netmask 255.255.240.0 -gateway 10.56.0.1 
add net 10.56.0.0: gateway 10.56.0.1: Network is unreachable
# ping 10.56.9.34
no answer from 10.56.9.34

Also added IP address of gateway (10.56.0.1) to /etc/defaultrouter:

# more /etc/defaultrouter
10.56.120.1
10.56.0.1

Are there any services that needs to be restarted for it to query gateway when looking up 10.56.9.34?

I have followed some instructions available from Googling but could not understand why they are not working here.

Thanks in advance,
George

seems you have two default routes, perhaps thats the problem.
have you tried with
-net 10.56.0.0 -netmask 255.255.0.0

Thanks for your suggestion,

It turned out that the printer NIC was faulty and had nothing to do with router configuration on Solaris 10.

Thanks all the same,

George
