IPv6 Interface
29
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 (608)
ip default-gateway (591)
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.
Example
This example specifies a full IPv6 address and prefix length.
Console(config)#interface vlan 1
Console(config-if)#ipv6 address 2001:DB8:2222:7272::72/96
Console(config-if)#end
Console#show ipv6 interface
VLAN 1 is up
