Configuring IP
Two static routes to 192.168.7.0/24:
--Interface-based route through
port 1/1, with metric 1.
--Standard static route through
gateway 192.168.8.11, with metric 3.
Router A
192.168.6.69/24
If route through interface
1/1 becomes unavailable,
192.168.8.11/24
When route through interface
1/1 is available, Router A always
uses that route.
192.168.6.188/24
Port 1/1
192.168.8.12/24
Port 4/4
Router B
Router A uses alternate
Router C Router D
route through gateway
192.168.8.11/24.
Figure 6.4 Standard and interface routes to the same destination network
To configure the multiple static routes of different types to the same destination, use either of the following
methods.
USING THE CLI
To configure a standard static IP route and a null route to the same network as shown in Figure 6.3 on page 6-44,
enter commands such as the following:
HP9300(config)# ip route 192.168.7.0/24 192.168.6.157/24 1
HP9300(config)# ip route 192.168.7.0/24 null0 3
The first command configures a standard static route, which includes specification of the next-hop gateway. The
command also gives the standard static route a metric of 1, which causes the routing switch to always prefer this
route when the route is available.
The second command configures another static route for the same destination network, but the second route is a
null route. The metric for the null route is 3, which is higher than the metric for the standard static route. If the
standard static route is unavailable, the software uses the null route.
For complete syntax information, see “Configuring a Static IP Route” on page 6-38.
To configure a standard static route and an interface-based route to the same destination, enter commands such
as the following:
HP9300(config)# ip route 192.168.6.0/24 ethernet 1/1 1
HP9300(config)# ip route 192.168.6.0/24 192.168.8.11/24 3
The first command configured an interface-based static route through Ethernet port 1/1. The command assigns a
metric of 1 to this route, causing the routing switch to always prefer this route when it is available. If the route
becomes unavailable, the routing switch uses an alternate route through the next-hop gateway 192.168.8.11/24.
