IPv6 anycast addresses identify a group of interfaces on different IPv6 nodes. Each group of interfaces is known as an anycast group. When a packet is sent to the anycast address, the anycast group member that is physically closest to the sender receives the packet.
The Oracle Solaris implementation of IPv6 does not support the creation of anycast addresses and groups. However, Oracle Solaris IPv6 nodes can send packets to anycast addresses. For more information, see Considerations for Tunnels to a 6to4 Relay Router.
