Backup Static Routes
Backup Static Routes Description
Static routes can become unavailable if the interface related to the currently
configured gateway is down. In this scenario, a backup static route can be
used instead.
In order to implement backup static routes, you need to prioritize them. The
priority values range from 1 to 8, with 1the highest priority. If there is more
than one gateway that belongs to the same priority, then a multipath static
route is installed. If a directly attached interface is down, then all the gateways
that belong to the interface are deleted from the list of next hop selections.
Backup static routes are useful for default routes, but they can be used for any
static route.
Creating a Backup Static Route
1.
Click
C
ONFIG
on the home page.
2.
Click the Static Routes link in the Routing Configuration section.
Note
This example assumes that a static route has already been configured
and the task is to add backup gateways.
3. Enter the IP address of the gateway in the A
DDITIONAL GATEWAY
edit
box.
4. Enter the priority value in the P
RIORITY
edit box; then click A
PPLY
.
The IP address of the additional gateway that you entered appears in the
Gateway column, and new
A
DDITIONAL GATEWAY
and P
RIORITY
edit
boxes are displayed.
To add more backup static routes, repeat steps 3 and 4.
