Configuring the Device
IP address configuration
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.
device(config)# interface ethernet 1/1/1
device(config)# ip address 10.45.6.1 255.255.255.0
You also can enter the IP address and mask in CIDR format.
device># ip address 10.45.6.1/24
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
Ruckus device.
To add a loopback interface, enter the interface loopback num and ip address num commands similar to the following
example.
device(config)# exit
device(config)# interface loopback 1
device(config)# ip address 10.0.0.1/24
You can specify from 1 through the maximum number of virtual interfaces supported on the device by using the interface
loopback num command.. To display the maximum number of virtual interfaces supported on the device, enter the show
default values command.
Assigning an IP address to a virtual routing interface
A virtual interface is a logical port associated with a Layer 3 Virtual LAN (VLAN) configured on a Layer 3 device. You can configure
routing parameters on the virtual interface to enable the Layer 3 device to route protocol traffic from one Layer 3 VLAN to the
other, without using an external router.
