Configuring IP parameters – Layer 3 Switches
To disable ICMP redirect messages globally, enter the following command at the global CONFIG
level of the CLI:
Brocade(config)# no ip icmp redirect
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:
Brocade(config)# interface ethernet 1/1/1
Brocade(config-if-e10000-1/1/1)# no ip redirect
Syntax: [no] ip redirect
Static routes configuration
The IP route table can receive routes from the following sources:
•Directly-connected networks – When you add an IP interface, the Layer 3 Switch automatically
creates a route for the network the interface is in.
•RIP – If RIP is enabled, the Layer 3 Switch can learn about routes from the advertisements
other RIP routers send to the Layer 3 Switch. If the route has a lower administrative distance
than any other routes from different sources to the same destination, the Layer 3 Switch
places the route in the IP route table.
•OSPF – Refer to RIP, but substitute “OSPF” for “RIP”.
•BGP4 – Refer to RIP, but substitute “BGP4” for “RIP”.
•Default network route – A statically configured default route that the Layer 3 Switch uses if
other default routes to the destination are not available. Refer to “Configuring a default
network route” on page54.
•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 I P 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 Layer 3 Switch interface through which you want the Layer 3 Switch 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.
