Adding a static IP route
To congure 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
congure a default route, enter the following.
device(config)# ip route 0.0.0.0 0.0.0.0
To
congure 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
congures a static IP route for destination network 192.128.2.69/24. Since an Ethernet port is specied instead of a
gateway IP address as the next hop, the Brocade device always forwards trac for the 192.128.2.69/24 network to port 1/4/1.
To congure 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 congured. 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 specied 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 congured on it. The
address does not need to be in the same subnet as the destination network.
