Adding a static IP route
To configure an IP static route with a destination address of 192.0.0.0 255.0.0.0 and a next-hop router IP address of 195.1.1.1, enter
the following.
device(config)# ip route 192.0.0.0 255.0.0.0 195.1.1.1
To configure a default route, enter the following.
device(config)# ip route 0.0.0.0 0.0.0.0
To configure a static IP route with an Ethernet port instead of a next-hop address, enter a command such as the following.
device(config)# ip route 192.128.2.69 255.255.255.0 ethernet 1/4/1
The command configures a static IP route for destination network 192.128.2.69/24. Since an Ethernet port is specified instead of a
gateway IP address as the next hop, the Brocade device always forwards traffic for the 192.128.2.69/24 network to port 1/4/1.
To configure an IP static route that uses virtual interface 3 as its next hop, enter a command such as the following.
device(config)# ip route 192.128.2.71 255.255.255.0 ve 3
Syntax: [no] ip route dest-ip-addr dest-mask | dest-ip-addr / mask-bits next-hop-ip-addr | ethernet unit / slot / port | ve num [ metric ]
[ tag num ] [ distance num ] [ name string ]
NOTE
Using the no form of the command only removes the name if configured. Another no command must be issued to remove the
actual Static Route.
The dest-ip-addr is the route’s destination. The dest-mask is the network mask for the route’s destination IP address. Alternatively, you
can specify the network mask information by entering / 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.
For a default route, enter 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx (use 0 for the mask-bits if you specify the address in CIDR format).
If you do not want to specify a next-hop IP address, you can instead specify a port or interface number on the Brocade device. The num
parameter is a virtual interface number. The unit/slot/port is the port’s number of the Brocade device. If you specify an Ethernet port, the
Brocade device forwards packets destined for the static route’s destination network to the specified interface. Conceptually, this feature
makes the destination network like a directly connected network, associated with a Brocade device interface.
NOTE
The port or virtual interface you use for the static route’s 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.
