IPv6 Addressing | 491
Assign an IPv6 Address to an Interface
IPv6 Addresses are supported on platforms c e s
Essentially IPv6 is enabled in FTOS simply by assigning IPv6 addresses to individual router interfaces.
IPv6 and IPv4 can be used together on a system, but be sure to differentiate that usage carefully. Use the
ipv6 address command to assign an IPv6 address to an interface.
Assign a Static IPv6 Route
IPv6 Static Routes are supported on platforms c e s
Use the ipv6 route command to configure IPv6 static routes.
Command Syntax Command Mode Purpose
ipv6 address ipv6 address/mask CONFIG-INTERFACE Enter the IPv6 Address for the device.
ipv6 address : x:x:x:x::x
mask : prefix length 0-128
IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a
colon (:). Omitting zeros is accepted as described in Addressing earlier in this chapter.
Command Syntax Command Mode Purpose
ipv6 route prefix type {slot/
port} forwarding router tag
CONFIGURATION Set up IPv6 static routes
prefix: IPv6 route prefix
type {slot/port}: interface type and slot/port
forwarding router: forwarding router’s address
tag: route tag
Enter the keyword interface followed by the type of
interface and slot/port information:
• For a 10/100/1000 Ethernet interface, enter the
keyword GigabitEthernet followed by the slot/port
information.
• For a Gigabit Ethernet interface, enter the keyword
GigabitEthernet followed by the slot/port information.
• For a 10 Gigabit Ethernet interface, enter the keyword
TenGigabitEthernet followed by the slot/port
information.
• For a loopback interface, enter the keyword loopback
followed by the loopback number
• For a linecard interface, enter the keyword linecard
followed by the slot number
• For a port-channel interface, enter the keyword
port-channel followed by the port-channel number
• For a VLAN interface, enter the keyword vlan
followed by the VLAN ID
• For a Null interface, enter the keyword null followed
by the Null interface number
