Configuring IP parameters for devices running Layer 3 software
This section describes how to configure IP parameters for devices running Layer 3 software.
Configuring IP addresses
You can configure an IP address on the following types of Layer 3 interfaces:
•
Ethernet port
•
Virtual routing interface (also called a Virtual Ethernet or "VE")
•
Loopback interface
By default, you can have up to 24 IP addresses on each interface, but you can increase this number to 128 IP addresses.
NOTE
Once you configure a virtual routing interface on a VLAN, you cannot configure Layer 3 interface parameters on individual
ports in the VLAN. Instead, you must configure the parameters on the virtual routing interface itself.
Assigning an IP address to an Ethernet port
Enter the following commands to assign an IP address to port 1/1/1.
Brocade(config)# interface ethernet 1/1/1
Brocade(config)# ip address 10.45.6.1 255.255.255.0
You also can enter the IP address and mask in CIDR format, as follows:
Brocade># ip address 10.45.6.1/24
Syntax:
[no] ip address
{
ip-addr
ip-mask
|
ip-addr
/
mask-bits
}
Assigning an IP address to a loopback interface
Loopback interfaces are always up, regardless of the states of physical interfaces. They can add stability to the network because they are
not subject to route flap problems that can occur due to unstable links between a Layer 3 device and other devices. You can configure up
to four loopback interfaces on a Layer 3 device.
You can add up to 24 IP addresses to each loopback interface.
NOTE
If you configure the device to use a loopback interface to communicate with a BGP4 neighbor, you must also configure a
loopback interface on the neighbor and configure the neighbor to use that loopback interface to communicate with the Brocade
device.
To add a loopback interface, enter commands such as those shown in the following example:
Brocade(config)# exit
Brocade(config)# interface loopback 1
Brocade(config)# ip address
10.0.0.1/24
Syntax:
interface loopback
num
The
num
parameter specifies the virtual interface number. You can specify from 1 through the maximum number of virtual interfaces
supported on the device. To display the maximum number of virtual interfaces supported on the device, enter the
show default values
command.
