EXAMPLE
The following example defines a default gateway for this device:
Console(config)#ipv6 default-gateway FE80::269:3EF9:FE19:6780
Console(config)#
RELATED COMMANDS
show ipv6 default-gateway (979)
ip default-gateway (963)
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 ip ipv6 address autoconfig command.
◆ If a link-local address has not yet been assigned to this interface, this
command will assign the specified static global unicast address and also
dynamically generate a link-local unicast address for the interface. (The
link-local address is made with an address prefix of FE80 and a host
portion based the switch’s MAC address in modified EUI-64 format.)
◆ If a duplicate address is detected, a warning message is sent to the
console.
