FIGURE 17 Standard and interface routes to the same destination network
To configure a standard static IP route and a null route to the same network as shown in Figure 16
on page 74, enter commands such as the following.
Virtual ADX(config)# ip route 192.168.7.0/24 192.168.6.157/24 1
Virtual ADX(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 Virtual
ADX 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, refer to “Configuring a static IP route” on page 70.
To configure a standard static route and an interface-based route to the same destination, enter
commands such as the following.
Virtual ADX(config)# ip route 192.168.6.0/24 ethernet 1/1 1
Virtual ADX(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 Virtual ADX to always prefer this route
when it is available. If the route becomes unavailable, the Virtual ADX uses an alternate route
through the next-hop gateway 192.168.8.11/24.
