文档介绍：? ICMPv6( RFC 2463 ) "Super" Protocol ? rfc4443 ? MLD (Multicast Listener Discovery) ( RFC 2710 ) – Based on IGMPv2 – Current version: MLDv2 ( RFC 3810 ) (= IGMPv3 in IPv4) ? Neighbor Discovery (ND) ( RFC 2461 -> rfc4861 ) – Neighbor cache – DAD - Duplicate Address Detection – Redirection – SEND - Secure Neighbor Discovery ( RFC 3971 ) ? Auto-configuration : – Stateless Address Autoconfiguration ( RFC 2462 -> rfc4862 ) – DHCPv6: Dynamic Host Configuration Protocol ( RFC 3315 ) – Path MTU discovery ( pMTU ) (RFC 1981) – Router Renumbering (RFC 2894 ) ? IPv6 DNS – IPv6 records and IPv6 transport ( RFCs related to DNS: 1886, 2672, 2673, 2874, 3363, 3364) – Current state of deployment (RFC 3901) Overview rfc 1112 IGMPv1 rfc2236 IGMPv2 rfc3376 IGMPv3 ? IPv6 nodes which share the same physical medium (link) use Neighbor Discovery (ND) ? not directly applicable to NBMA ( Non Broadcast Multi Access) networks (RFC 2491), ND uses multicast for certain services. ? ND is a sub-protocol of ICMPv6 , that is, ND message types are a subset of the set of ICMPv6 messages, and ND messages are identified in IPv6 packets by a preceding Next Header value of 58. 3 Neighbor Discovery (RFC 2461) -> rfc4861 Type Meaning 1 Destination Unreachable 2 Packet Too Big 3 Time Exceeded 4 Parameter Problem 128 Echo Request 129 Echo Reply 130 Group Membership Query 131 Group Membership Report 132 Group Membership Reduction 133 Router Solicitation 134 Router Advertisement 135 Neighbor Solicitation 136 Neighbor Advertisement 137 Redirect 144 ICMP Home Agent Address Discovery Request Message 145 ICMP Home Agent Address Discovery Reply Message 146 ICMP Mobile Prefix Solicitation Message Format 147 ICMP Mobile Prefix Advertisement Message Format Types of ICMPv6 messages RFC 2461 RFC 4861 RFC 3775 RFC 2710 RFC 2463 Packets Usage IPv4 Neighbor Functions and IPv6 Equivalents IPv4 Neighbor Function IPv6 Neighbor Function ARP Request message Neighbor Solicitat
