Using Routing Commands

To display the contents of the routing table, use the command netstat with the -R option. To make a manual change to the routing table, use the route command with the add or delete option. For example,

% 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

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, an SL range from C to TS, a RIPSO label = top_secret sci, and a RIPSO error = genser;sci. 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 (t
op_secret sci),ripso_error=0xa0000000 (genser;sci)
        metric=3,min_sl=ADMIN_LOW,max_sl=S,doi=3
