ipv6 address eui-64
Congures a global IPv6 address on an interface by entering only the network prex and length.
Syntax
ipv6 address ipv6-prefix/prefix-length eui-64
Parameters ipv6-prex — Enter an IPv6 prex in x:x::y/mask format.
Defaults None
Command Mode INTERFACE
Usage Information Use this command to manually congure an IPv6 address in addition to the link-local address generated with
stateless autoconguration. Specify only the network prex and length. The 64-bit interface ID is automatically
computed from the MAC address. This command enables IPv6 processing on the interface. The no version of this
command removes the IPv6 address conguration.
Example
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# ipv6 address 2111:dddd:0eee::/64 eui-64
Supported Releases 10.4.0E(R1) or later
ipv6 address link-local
Congures a link-local IPv6 address on the interface to use instead of the link-local address that is automatically congured with stateless
autoconguration.
Syntax
ipv6 address ipv6-prefix link-local
Parameters ipv6-prefix — Enter an IPv6 prex in x:x::y/mask format.
Defaults None
Command Mode INTERFACE
Usage Information
• An interface can have only one link-local address. By default, an IPv6 link-local address is automatically
generated with a MAC-based EUI-64 interface ID when a router boots up and IPv6 is enabled. Use this
command to manually congure a link-local address to replace the autocongured address. For example, to
congure a more user-friendly link-local address, replace fe80::eef4:bbff:fefb:fa30/64 with
fe80::1/64.
•
The no version of this command removes the specied link-local address.
Example
OS10(config)# interface mgmt 1/1/1
OS10(conf-if-ma-1/1/1)# ipv6 address 2111:dddd:0eee::22/64 link-local
Supported Releases 10.4.0E(R1) or later
ipv6 hop-by-hop
Enables and disables processing hop-by-hop options in IPv6 packet headers.
Syntax
ipv6 hop-by-hop
Parameters None
Defaults Hop-by-hop header options in an IPv6 packet are not processed on an interface.
