IP Addressing Commands 221ExampleThe following example configures an IPv6 address FE80::260:3EFF:FE11:6770 for interface g1.ipv6 address link-localThe ipv6 address link-local Interface Configuration mode command configures an IPv6 link-localaddress for an interface. Use the no form of this command to return to the default link local address onthe interface.Syntax• ipv6 address ipv6-address link-local• no ipv6 address link-local• ipv6-address — The IPv6 network address assigned to the interface. The address is specified inhexadecimal using 16-bit values between colons.Default ConfigurationIPv6 is enabled on the interface. Link local address of the interface is FE80::EUI64 (interface MACaddress).Command ModeInterface configuration (Ethernet, VLAN, Port-channel). Cannot be configured for a range ofinterfaces (range context).User Guidelines• Using the no ipv6 link-local address command removes the manually configured link local IPv6address from an interface. Multiple IPv6 addresses can be configured per interface, but only one link-local address. When the no ipv6 link-local address command is used, the interface is reconfigured withthe standard link local address (the same IPv6 link-local address that is set automatically when theenable ipv6 command is used). The system automatically generates a link-local address for an interfacewhen IPv6 processing is enabled on the interface. To manually specify a link-local address to be used byan interface, use the ipv6 link-local address command. The system supports only 64 bits prefix lengthfor link-local addresses.Console# Console (config)# interface g1Console (config-if)# ipv6 address FE80::260:3EFF:FE11:67705400_CLI.book Page 221 Wednesday, December 17, 2008 4:33 PM
