IPv6 Interface
– 907 –
◆ An IPv6 default gateway must be defined if a destination is located in a
different IP segment. An IPv6 default gateway can only be successfully set
when a network interface that directly connects to the gateway has been
configured on the switch.
Example
The following example defines a default gateway for this device:
Console(config)#ipv6 default-gateway FE80::269:3EF9:FE19:6780%1
Console(config)#
Related Commands

show ip route (949)
ip default-gateway (896)
ipv6 address This command configures an IPv6 global unicast address and enables IPv6 on an
interface. Use the no form without any arguments to remove all IPv6 addresses
from the interface, or use the no form with a specific IPv6 address to remove that
address from the interface.
Syntax
[no] ipv6 address ipv6-address[/prefix-length]
ipv6-address - A full IPv6 address including the network prefix and host
address bits.
prefix-length - A decimal value indicating how many contiguous bits (from
the left) of the address comprise the prefix (i.e., the network portion of the
address).
Default Setting
No IPv6 addresses are defined
Command Mode
Interface Configuration (VLAN)
Command Usage
◆ All IPv6 addresses must be according to RFC 2373 “IPv6 Addressing
Architecture,” using 8 colon-separated 16-bit hexadecimal values. One double
colon may be used in the address to indicate the appropriate number of zeros
required to fill the undefined fields.
◆ To connect to a larger network with multiple subnets, you must configure a
global unicast address. This address can be manually configured with this
command, or it can be automatically configured using the ipv6 address
autoconfig command.
