To configure the Cisco X:X:X:X::X/IPv6 addresses on an interface using the IPv6 address <0-128> command in interface configuration mode. Note IPv6 addressing does not explicitly address the subnet mask, but using the CIDR notation. Example IPv4 address 10.55.82.23/24,IPv6 address: 2001:dabd:32bf::1/64. Keep in mind that a host ID portion of the IPv6 address is 64 bits in length. (Half of the IPv6 IP address)
Auto IPv6 advantages one of one node to automatically set a globally unique IPv6 addresses do not need IPv6 DHCP server capability is very attractive, looks forward to the same enterprise of a dime.
Diving in front of you to configure IPv6 settings for the first time let us dive into the depth and how it works and more. The IPv6 Neighbor Discovery protocol uses a (NDP), which makes IPv6-and-plug and play features a unique mechanism. NDP performs multiple functions are listed below;
Router discovery assistance--to find there is no DHCP server node for the local router on the network segment.
Parameter discovery – a node discovery link parameters, such as its ability to link MTU and hop limit.
Prefix discovery--to find the prefix or prefixes assigned to the specific IPv6 node of the link capacity.
Automatic setting – node address to identify its complete unique addresses does not have DHCP server capability.
Duplicate address detection (dad)-capacity, but to identify one of the nodes or IPv6 address, it attempts to use already exists.
Address resolution – a node to discover does not use address resolution Protocol (ARP) link-layer addresses of other nodes on the link capacity.
Next-hop determination – the ability for a node to determine the next network link layer link; target the local router or node.
Neighbor unreachability detection – the ability to determine when the interfaces on the device node of the network link is no longer reachable.
Reset--path of routers to inform hosts of a better ability to reach the given destination.
IPv6 Stateless on an interface configuration set automatically the first time you configure the router to propagate them prefixes using the NDP router advertisement (RA) message link. Without this advertising network links will not know what address is automatically set to the host.
Advertise Cisco router Ethernet interface you want to configure neighbors set IPv6 IPv6 prefix, you must first enable IPv6 unicast routing on the router through global implementation of IPv6 unicast routing commands. IPv6 unicast routing is enabled, you can then proceed to configure the prefix advertised by using the IPv6 ND prefix x:x:x:x::/x command in interface configuration mode. Once you have configured the prefix, the router advertisement specified in Network Discovery Protocol (NDP), router advertisement (RA) and regularly received router solicitation (RS) after the interface prefix.
In this lab, you will configure the FastEthernet0/0 interfaces of R1 and R2, and R1 and R2 static allocation of globally-unique IPv6 unicast address will automatically set its globally unique IPv6 address link.
Familiarize yourself with the following new command(s);
Configure R1 ′ s FastEthernet0/0 interface's IPv6 address; 2001:Abad:beef::1/64.
Configure R1 ′ s FastEthernet0/0 interface to advertise 2001:Abad:beef::/64 prefix NDP router advertisements on an Ethernet segment.
R2 ′ s FastEthernet0/0 interface configuration is automatically set to its unique global unicast IPv6 addresses, please wait a few minutes and verify the interface automatically sets globally unique IPv6 addresses.
Verify IPv6 traffic between the R2 and R1 use Ping.
