Configuring IP parameters
19
The donor interface must be one of the following:
• Loopback interface
• VE interface
• Ethernet interface (can be part of a LAG interface; must be untagged if in a VLAN)
The unnumbered interfaces can be the following:
• VE interface
• Ethernet interface (must be untagged if in a VLAN)
Configuring an unnumbered interface
To enable an unnumbered interface to inherit the IP address of a donor interface, enter commands
such as the following:
Brocade (config)# interface ve 10
Brocade (config-vif-10)# ip unnumbered ve 9
The commands enable interface ve 10 to inherit the IP address of ve 9. Interface ve 10 is the
unnumbered interface and interface ve 9 is the donor interface.
Syntax: [no] ip unnumbered [ ethernet slot/port | ve num | loopback num ]
The ethernet slot/port parameter specifies the donor interface by an Ethernet port number.
The ve num parameter specifies the donor interface by virtual interface number.
The loopback num parameter specifies the donor interface by loopback interface number.
Use the no ip unnumbered command to remove the IP address from the unnumbered interface.
NOTE
You do not need to configure an interface to be a donor interface. An interface becomes a donor
interface automatically when an unnumbered interface inherits its IP address.
Displaying unnumbered interfaces
The show ip interface command displays information about unnumbered interfaces.
In the following example, note that interfaces ve 9 and ve 10 have the same IP address. Interface
ve 10 is an unnumbered interface, as indicated by the U in the Flag column.
Brocade# show ip interface
Interface IP-Address OK? Method Status Protocol VRF FLAG
mgmt 1 10.21.108.35 YES NVRAM up up default-vrf
ve 6 6.1.1.1 YES NVRAM up up default-vrf
ve 9 1.1.1.1 YES NVRAM up up default-vrf
ve 10 1.1.1.1 YES NVRAM up up default-vrf U
In the following example, the first highlighted line indicates that interface ve 10 is an unnumbered
interface, inheriting the IP address of ve 9, which is the donor interface.
Brocade# show ip interface ve 10
Interface Ve 10
