Usage Information
Neighbor Discovery Protocol for IPv6 is defined in RFC 2461 as part of the Stateless
Address Autoconfiguration protocol. It replaces the Address Resolution Protocol
used with IPv4. It defines mechanisms for solving problems, such as:
• Router discovery: Hosts can locate routers residing on a link
• Prefix discovery: Hosts can discover address prefixes for the link.
• Parameter discovery
• Address autoconfiguration — configuration of addresses for an interface
• Address resolution — mapping from IP address to link-layer address
• Next-hop determination• Neighbor Unreachability Detection (NUD): Determine
that a neighbor is no longer reachable on the link
• Duplicate Address Detection (DAD): Allow a node to check whether a proposed
address is already in use.
• Redirect: The router can inform a node about a better first-hop.
Use the ipv6 neighbor command to manually configure the IPv6 address of a
neighbor to be discovered by the switch.
ipv6 ospf area
Enable IPv6 OSPF on an interface.

To disable OSPFv6 routing for an interface, use the no ipv6 ospf process-id
area area-id command.
Parameters
process-id Enter the process identification number.
area area-id Specify the OSPF area. The range is from 0 to 65535.
Defaults none
