Add a route persistently:
#
route -p add default ip-address
Eg:
#
route -p add 192.168.10.0/24 172.16.0.10
-p Make changes to the network route
tables per-
sistent across system
restarts. The operation
is applied to
the network routing
tables
first and, if successful, is then applied to
the list of
saved routes used
at system
startup. In determining whether an operation
was successful, a failure
to add a route that
already exists
or to delete a route that is
not in the routing table is
ignored. Particu-
lar care
should be taken when using host or
network names
in persistent routes,
as
network-based name
resolution services are
not available at the time
routes are added at
startup.
(Reference :Solaris man page)
For routes that are created by using this method,
use following command
to display all of the static routes
#route -p show
Following examples creates an IPv4 route to the destination
192.168.10.0 and subnet with the subnet mask of 255.255.255.0(/24):
#
route add 192.168.10.0/24 somegateway
#
route add 192.168.10.0 -netmask 255.255.255.0 somegateway
#
route add 192.168.10.0 somegateway 255.255.255.0
For IPv6, only “/” format
is accepting for subnet. The following example creates an IPv6 route to the
destination 35dd:: with netmask of 16 one-bits followed by 112 zero-bits.
# route add -inet6 35dd::/16
somegateway
