Parameters

ipv6-address/prefix-length: Specifies an IPv6 address and IPv6 prefix length. The ipv6-address and prefix-length arguments jointly specify the prefix of an EUI-64 IPv6 address. The value range for the prefix-length argument is 1 to 64.

Usage guidelines

An EUI-64 IPv6 address is generated based on the specified prefix and the automatically generated interface identifier and is displayed by using the display ipv6 interface command.

The prefix length of an EUI-64 IPv6 address cannot be greater than 64.

Examples

# Configure an EUI-64 IPv6 address for VLAN-interface 100. The prefix of the address is the same as that of 2001::1/64, and the interface ID is generated based on the MAC address of the device.
