Routing apparatus for supporting IPv6 anycast service and method thereof
First Claim
1. An anycast routing apparatus comprising:
- a receiving unit receiving a neighbor discovery protocol (NDP) message;
a routing entry unit adding or deleting a host route for an IPv6 anycast address and a neighbor entry for the IPv6 anycast address according to the NDP message, if the NDP message comprises the IPv6 anycast address; and
an anycast address manager managing the host route or the neighbor entry according to a neighbor unreachability detection (NUD) process.

Abstract
A routing apparatus for supporting an IPv6 anycast service and a method thereof are provided. The anycast routing apparatus includes: a receiving unit receiving a neighbor discovery protocol (NDP) message; a routing entry unit adding or deleting a host route for an IPv6 anycast address and a neighbor entry for the IPv6 anycast address according to the NDP message, if the NDP message includes the IPv6 anycast address; and an anycast address manager managing the host route or the neighbor entry according to a neighbor unreachability detection (NUD) process. Accordingly, an IPv6 anycast address can be transmitted between a host and a router, thereby configuring routing information effectively.
