The following example shows how to enable IPv6:

Switch# configure terminal
Switch(config)# ipv6 enable

7.3.2. max-static-v6routes

ipv6 address LINK-LOCAL link-local

no ipv6 address LINK-LOCAL link-local

ipv6 address auto link-local

no ipv6 address auto link-local

no ipv6 address

Parameter

Parameter Description

Parameter Value

GOLBAL_FREFIX

Global IPv6 address and prefix length. In X:X::X:X/M format

IPv6 Address and mask length in X:X::X:X/M format

LINK-LOCAL

Link-local IPv6 address. In X:X::X:X format

IPv6 Address in X:X::X:X format

Command Mode

Interface Configuration

Default

There is not any ipv6 address on the interface by default.

Usage

Use this command to configure ipv6 address on the interface. Use the no form of this command to remove the ipv6 address. This configuration should not affect the ipv4 functions and other ipv6 configuration on the interface.

The maximum count of the Link-local address is 1; the maximum count of the global address address is 8.

Use this command with the keyword “auto link-local” to automatically generate a link-local address, if there is no link-local address on this interface. Use the no form of this command with the keyword “auto link-local” to remove the automatically generated link-local address, if there is only that automatically generated link-local address left on this interface.

Use this command with a specified ipv6 address (e.g. 3ffe:506::1/48) to configure a global unicast ipv6 address. Use this command with the keyword “eui-64” to generate interface id automatically by the eui-64 algorithm. The global address should not be same. Use the no form of this command the remove the specified ipv6 global unicast address.

If there is no link-local address on the interface, system should automatically generate one when configure a global unicast ipv6 address.

Use this command with a specified ipv6 address (e.g. fe80::1) and a keyword “link-local” to configure a link-local address. Use the no form of this command with the specified ipv6 address and the keyword “link-local” to remove the specified ipv6 link-local address. The specified link-local address has a higher priority than the automatically generated the link-local address, that can overwrite the automatically generated one.

Use the no form of this command without any parameters or keywords to remove all ipv6 addresses on the interface, include ipv6 global addresses and link-local addresses.

Examples

The following example shows how to configure link local address and global unicast address:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# ipv6 address fe80::1233 link-local
Switch(config-if)# ipv6 address 3001:1::1234/64
