The implementation of ISATAP router

ISATAP is an IPv6 transition mechanism that allows IPv6-in-IPv4 tunnels to be created automatically within a site. Each host queries an ISATAP router within the site to obtain address and routing information. Packets sent to the IPv6 Internet are routed via the ISATAP router, and packets destined for other hosts within the same site are tunneled directly to the destination. Since the ISATAP router must to be a key player above the mechanism, this paper is trying to show the implementation ISATAP router based on Linux platform
