Revision 1.14.3 54 RX1000/RX1100™
Note
A "blackhole", or "null" route may be installed by entering "null0" in the interface field.
The Metric field specifies an integer cost metric for the route, which is used when choosing among
multiple routes in the routing table that most closely match the destination address of a packet being
forwarded. The route with the lowest metric is chosen as the active route.
Note
Multiple routes to the same destination subnet may also be specified using identical metrics in
order to create multipath routes. Please refer to
Multipath .
The Comment field shows the status of the static route, and provides a basic cause when the route
is not installable.
The Save button below the table will perform the following sanity checks on routing entries that have
been added or modified. If the tests pass, the routes will be saved and immediately installed.
• A specified Gateway must be reachable, and if a network interface is also specified, must be
reachable via that interface.
• If a specified network interface exists but is not active, the static route will be installed and
marked, "Inactive (interface is not active)".
• If a specified network interface does not exist (e.g. an on-demand modem PPP connection) the
static route will be installed and marked, "Inactive (interface does not exist)".
Delete routes by removing their Network/Mask addresses before saving.
Note
In order to redistribute static routes to other routers, the Redistribute Static option must be
enabled in the corresponding OSPF, RIP, or BGP configuration's Global parameters menu in
Webmin.
5.3.3.2. Other Static Routes
This table will be shown if there are active static routes which were not configured manually in the
Configured Static Routes table. The Save to Configured Static Routes link next to each route
entry in this table will make the corresponding route permanent.
Note
There are situations where manually entered routes should not be converted, e.g. routes
dynamically added by IPsec and GRE tunnels. Making these routes permanent may cause the
daemons that add them to fail.
