PROTOCOL-INDEPENDENT CONFIGURATION COMMANDS
The following sections detail the Protocol-independent configuration commands in
the OmniAccess 5740 USG.

ONFIGURE STATIC ROUTES
Static routes are user-defined routes that cause packets moving between a
source and a destination to take a specified path. Static routes can be important if
the routing protocol cannot build a route to a particular destination.
When an interface goes down, all static routes through that interface are removed
from the IP routing table. Also, when the address specified for the forwarding
router in a static route is invalid (not reachable), the static route is removed from
the IP routing table.
• Static routes for Point-to-point links (like Serial, GRE tunnel interfaces) can be
configured without Gateway IP address.
• Static routes for Ethernet interfaces have to be configured with gateway IP
address.
• If gateway address as well as interface name is specified in the static route, then
route is activated only if gateway is reachable through the specified interface.
Router might not be able to determine the routes to all other networks. In that
case, you can configure default static route.
Note: You can override static routes with dynamic routing information by assigning
administrative distance.
You can configure route for same network through different interfaces, and with
different weights. In this case, route with less administrative distance is used for
forwarding. But, when route with less administrative distance becomes unreachable,
router starts using route with the next highest administrative distance.

XAMPLE
ALU(config)# ip route 1.1.1.0/24 2.2.2.2
Command (in CM) Description
ip route {vrf <name>|destination
network subnet-mask|destination
network/prefix-length} {<gateway-ip-
address>|<interface-name> [<gateway-
ip-address>]}[<1-255>]
This command is used to
configure a static route.
