60 IPv6 Interface Commands

universal/local bit in the address and inserting the hexadecimal number FFFE between the upper and lower three bytes of the of the MAC address.

For example, if a device had an EUI-48 address of 28-9F-18-1C-82-35, the global/local bit must first be inverted to meet EUI-64 requirements (i.e., 1 for globally defined addresses and 0 for locally defined addresses), changing 28 to 2A. Then the two bytes FFFE are inserted between the OUI (i.e., company id) and the rest of the address, resulting in a modified EUI-64 interface identifier of 2A-9F-18-FF-FE-1C-82-35.

•This host addressing method allows the same interface identifier to be used on multiple IP interfaces of a single device, as long as those interfaces are attached to different subnets.

Example

This example uses the general network prefix of 2001:0DB8:0:1::/64 used in an earlier example, and specifies that the EUI-64 interface identifier be used in the lower 64 bits of the address.

Console(config)#interface vlan 1 Console(config-if)#ipv6 address 2001:0DB8:0:1::/64 eui-64 Console(config-if)#end

Console#show ipv6 interface Vlan 1 is up

IPv6 is enable. Link-local address:

FE80::200:E8FF:FE90:0/64 Global unicast address(es):

2001:DB8::1:200:E8FF:FE90:0, subnet is 2001:DB8:0:1::/64 Joined group address(es):

FF01::1/16

FF02::1/16

FF02::1:FF90:0/104 MTU is 1500 bytes.

ND DAD is enabled, number of DAD attempts: 1. ND retransmit interval is 1000 milliseconds
