Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 64)

NOTE
Some FSX devices do not generate ICMP redirect and network unreachable messages.
NOTE
The device forwards misdirected traffic to the appropriate router, even if you disable the redirect
messages.
By default, IP ICMP redirect over global level is disabled and a Brocade Layer 3 Switch does not send
an ICMP redirect message to the source of a misdirected packet in addition to forwarding the packet to
the appropriate router. To enable ICMP redirect messages globally, enter the following command at
the global CONFIG level of the CLI:
device(config)# ip icmp redirect
Syntax: [no] ip icmp redirect
To disable ICMP redirect messages on a specific virtual interface, enter the following command at the
configuration level for the virtual interface:
Brocade(config-vlan-10)# interface ve 10
Brocade(config-vif-10)# 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.
• 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:
