How do you EUI-64 based host portion in an IPv6 address?
The IPv6 EUI-64 format address is obtained through the 48-bit MAC address. The MAC address is first separated into two 24-bits, with one being OUI (Organizationally Unique Identifier) and the other being NIC specific. The 16-bit 0xFFFE is then inserted between these two 24-bits for the 64-bit EUI address.
How is EUI-64 address calculated?
You could (in interface configuration mode of your Cisco IOS router) enter the command:
- ipv6 address 2000:1::/64 eui-64.
- SCENARIO: Router R1 has a MAC address of 0015.2BE4.
- Step #1: Split the MAC address in the middle:
- Step #2: Insert FF:FE in the middle:
- Step #3: Change the format to use a colon delimiter:
What is used in the EUI-64 process to generate an interface ID for IPv6 on an interface that supports IPv6?
the MAC address of the IPv6 enabled interfacea randomly generated 64-bit hexadecimal addressan IPv6 address that is provided by a DHCPv6 serveran IPv4 address that is configured on the interfaceExplanation:The EUI-64 process uses the MAC address of an interface toconstruct an interface ID (IID).
Which IPv6 prefix is reserved?
Which IPv6 prefix is reserved for communication between devices on the same link? Answers Explanation & Hints: IPv6 link-local unicast addresses are in the FE80::/10 prefix range and are not routable. They are used only for communications between devices on the same link.
Is IPv6 the same as MAC address?
Address Length and Representation: In IP address, Ipv4 has an address length of 32-bits, while IPv6 has an address length of 128-bits. On the other hand, the MAC address is a 48-bits address. Also, the IP address is represented in the binary format with dots(.)
What is the subnet ID of the IPv6 unicast address?
IN IPv6, the subnet ID defines an administrative subnet of the network and is up to 16 bits in length. You assign a subnet ID as part of IPv6 network configuration. The subnet prefix defines the site topology to a router by specifying the specific link to which the subnet has been assigned.
Which IPv6 address is a global unicast address?
Global Unicast Address. Global unicast addresses (GUAs), also known as aggregatable global unicast addresses, are globally routable and reachable in the IPv6 Internet. They are equivalent to public IPv4 addresses. They play a significant role in the IPv6 addressing architecture.
What method can be used to generate an interface is by an IPv6 host that is using Slaac?
What two methods can be used to generate an interface ID by an IPv6 host that is using SLAAC? (Choose two.) Explanation: A host that is using SLAAC has two means to configure an interface ID: EUI-64 and random generation by the host operating system.
What are the two methods a device can use to generate its own IPv6 interface ID?
An interface ID must be unique within the subnet. IPv6 hosts can use the Neighbor Discovery protocol to automatically generate their own interface IDs. Neighbor Discovery automatically generates the interface ID, based on the MAC or EUI-64 address of the host’s interface.
