To display the contents of the routing table, use the netstat --R command. To make a manual change to the routing table, use the route command with the add or delete option. For example, the following route command adds to the routing table a loop with the hosts at 129.150.115.0 and 129.150.118.39 with a distance metric of 2, a Label range from C to TS, a RIPSO label = top_secret sci, and a RIPSO error = genser;sci.
$ route add net 129.150.115.0 129.150.118.39 \ -m metric=2,min_sl=c,max_sl=ts,ripso_label="top_secret sci",\ ripso_error="genser;sci" add net 129.150.115.0: gateway 129.150.118.39
To see the results of the added loop, type:
$ netstat -Rn ... 129.150.115.0 129.150.118.39 UG 0 0 metric=2,min_sl=C,max_sl=TS, ripso_label=0x3d 0x20000000 (top_secret sci), ripso_error=0xa0000000 (genser;sci) ...
The new route is shown above. The other routes are replaced by ellipses (...). A second example of adding a route with two new emetrics and viewing the new routing table follows:
$ route add net 129.150.114.0 129.150.118.39 \ -m metric=3,min_sl=admin_low,max_sl=s,doi=3 \ -m metric=4,min_sl=c,max_sl=admin_high,doi=4,\ ripso_label="top_secret sci",ripso_error="genser;sci" add net 129.150.114.0: gateway 129.150.118.39 $ netstat -Rn ... 129.150.115.0 129.150.118.39 UG 0 0 metric=2,min_sl=C,max_sl=TS, ripso_label=0x3d 0x20000000 (top_secret sci), ripso_error=0xa0000000 (genser;sci) 129.150.114.0 129.150.118.39 UG 0 0 metric=4,min_sl=C,max_sl=ADMIN_HIGH,doi=4, ripso_label=0x3d 0x20000000 (top_secret sci), ripso_error=0xa0000000 (genser;sci), metric=3,min_sl=ADMIN_LOW,max_sl=S,doi=3 ...
