What is the method a device can use to generate its own IPv6 interface ID?
Neighbor Discovery protocol
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.
How do I enable Slaac on an interface?
Enable IPv6 SLAAC on Cisco Routers
- Step-1. Enable IPv6 Routing on R6.
- Step-2. Enable IPv6 and Add prefix on R6: interface Ethernet0/1. ip address 192.168.100.10 255.255.255.0.
- Step-3. Enable IPv6 Routing on R1. R1(config)#ipv6 unicast-routing.
- Step-4. Enable IPv6 and configure IPv6 auto-config R1: interface Ethernet0/0.
How to configure a Static IPv6 address on a VLAN?
This option enables configuring of unique, static unicast IPv6 addresses for global and link-local applications, including: link-local unicast (including EUI and non-EUI interface identifiers) global unicast (and unique local unicast) If IPv6 is not already enabled on the VLAN, this command enables IPv6 and configures a static link-local address.
How to add an IPv6 address to an interface?
The default prefix type is set as unicast. You can configure the prefix type as anycast, eui64, or link-local address by defining the prefix type in the command. Configure the IPv6 link-local address for the interface. SEFOS(config-if)# ipv6 address fe80::203:2ff:fe03:501 link-localSEFOS(config-if)# end
Is it possible to disable IPv6 on a VLAN?
If IPv6 was enabled only by a statically configured link-local address, deleting the link-local address disables IPv6 on the VLAN.
What is the prefix for a Static IPv6 address?
NOTE: An existing link-local address is replaced, and is not deprecated, when a static replacement is configured. The prefix for a statically configured link-local address is always 64 bits, with all blocks after fe80 set to zero. That is: fe80:0:0:0.
