Section7.1.4.3
Deleting an IPv6 Address
To delete an IPv6 address for a routable interface, do the following:
1. Make sure the CLI is in Configuration mode.
2. Delete the address by typing:
no ip interface ipv6 address address
Where:
• interface is the name of the interface
• address is the IPv6 address
3. Type commit and press Enter to save the changes, or type revert and press Enter to abort.
Section7.1.5
Configuring IPv6 Neighbor Discovery
The Neighbor Discovery (ND) protocol in IPv6 is a replacement for IPv4 ARP messages. The protocol uses ICMPv6
messages with for various purposes including:
• Find a link-layer address of a neighbor
• Discover neighbor routers
• Determine any change in the link-layer address
• Determine when a neighbor is down
• Send network information from routers to hosts, which includes hop limit, MTU size, determining the network
prefix used on a link, address auto configuration, and the default route information
The Neighbor Discovery protocol uses five types of ICMPv6 messages:
• Router Solicitation (ICMPv6 type 133)
This message is sent by hosts to routers as a request to router advertisement message. It uses a destination
multicast address (i.e. FF02:2).
• Router Advertisement Messages (ICMPv6 type 134)
This message is used by routers to announce its presence in a network. The message includes network
information related to IPv6 prefixes, default route, MTU size, hop limit and auto configuration flag. It uses a
destination multicast address (i.e. FF02:1).
• Neighbor Solicitation Messages (ICMPv6 type 135)
This message is sent by hosts to determine the existence of another host on the same link. The goal is to find
the link-layer of neighboring nodes.
• Neighbor Advertisement Messages (ICMPv6 type 136)
This message is sent by hosts to indicate the existence of the host and it provides information about its own
link-layer address.
• Redirect Messages (ICMPv6 type 137)
This message is sent by a router to inform a host about a better router to reach a particular destination address.
Neighbor Discovery should be configured on all Ethernet interfaces enabled for IPv6.
To enable and configure settings for IPv6 Neighbor Discovery, do the following:
