Configuring IP parameters – Layer 3 Switches
Brocade(config)# ip route 192.128.2.71 255.255.255.0 ve 3
The command in the following example configures an IP static route that uses port 2/2 as its next
hop.
Brocade(config)# ip route 192.128.2.73 255.255.255.0 ethernet 2/2
Syntax: ip route <dest-ip-addr> <dest-mask>
<next-hop-ip-addr> |
ethernet [<slotnum>/]<portnum> | ve <num>
[<metric>] [distance <num>]
or
Syntax: ip route <dest-ip-addr>/<mask-bits>
<next-hop-ip-addr> |
ethernet [<slotnum>/]<portnum> | ve <num>
[<metric>] [distance <num>]
The <dest-ip-addr> is the route destination. The <dest-mask> is the network mask for the route
destination IP address. Alternatively, you can specify the network mask information by entering a
forward slash followed by the number of bits in the network mask. For example, you can enter
192.0.0.0 255.255.255.0 as 192.0.0.0/.24.
The <next-hop-ip-addr> is the IP address of the next-hop router (gateway) for the route.
If you do not want to specify a next-hop IP address, you can instead specify a port or interface
number on the Layer 3 Switch. The <num> parameter is a virtual interface number. If you instead
specify an Ethernet port, the <portnum> is the port number (including the slot number, if you are
configuring a Chassis device). In this case, the Layer 3 Switch forwards packets destined for the
static route destination network to the specified interface. Conceptually, this feature makes the
destination network like a directly connected network, associated with a specific Layer 3 Switch
interface.
NOTE
The port or virtual interface you use for the static route next hop must have at least one IP address
configured on it. The address does not need to be in the same subnet as the destination network.
The <metric> parameter can be a number from 1 through 16. The default is 1.
NOTE
If you specify 16, RIP considers the metric to be infinite and thus also considers the route to be
unreachable.
The distance <num> parameter specifies the administrative distance of the route. When
comparing otherwise equal routes to a destination, the Layer 3 Switch prefers lower administrative
distances over higher ones, so make sure you use a low value for your default route. The default is
1.
NOTE
The Layer 3 Switch will replace the static route if the it receives a route with a lower administrative
distance. Refer to “Administrative distance” on page 1265 for a list of the default administrative
distances for all types of routes.
NOTE
You can also assign the default router as the destination by entering 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx.
