Configuring forwarding parameters

NOTE
The device forwards misdirected traffic to the appropriate router, even if you disable the redirect
messages.
To disable ICMP redirect messages globally, enter the following command at the global CONFIG
level of the CLI.
BigIron RX(config)# no ip icmp redirects
Syntax: [no] ip icmp redirects
To disable ICMP redirect messages on a specific interface, enter the following command at the
configuration level for the interface.
BigIron RX(config)# interface ethernet 3/11
BigIron RX(config-if-e100-3/11)# no ip redirect
Syntax: [no] ip redirect
Configuring static routes
The IP route table can receive routes from the following sources:
• Directly-connected networks – When you add an IP interface, the device automatically creates
a route for the network the interface is in.
• RIP – If RIP is enabled, the device can learn about routes from the advertisements other RIP
routers send to the device. If the route has a lower administrative distance than any other
routes from different sources to the same destination, the device places the route in the IP
route table.
• OSPF – See RIP, but substitute “OSPF” for “RIP”.
• BGP4 – See RIP, but substitute “BGP4” for “RIP”.
• Statically configured route – You can add routes directly to the route table. When you add a
route to the IP route table, you are creating a static IP route. This section describes how to add
static routes to the IP route table.
Static route types
You can configure the following types of static IP routes:
• Standard – the static route consists of the destination network address and network mask,
and the IP address of the next-hop gateway. You can configure multiple standard static routes
with the same metric for load sharing or with different metrics to provide a primary route and
backup routes.
• Interface-based – the static route consists of the destination network address and network
mask, and the device interface through which you want the device to send traffic for the route.
Typically, this type of static route is for directly attached destination networks.
• Null – the static route consists of the destination network address and network mask, and the
“null0” parameter. Typically, the null route is configured as a backup route for discarding traffic
if the primary route is unavailable.
Static IP route parameters
When you configure a static IP route, you must specify the following parameters:
