Notes on IPv6

Aggregatable Global Unitcast Address	2000 - 3FFF: Original Routable Addresses
Link-Local Unicast Addresses	FE80: 1/1024th of all available for Link only, used to get Global Unicast Address via a Router or a DHCP.
Site-Local Unicast Addresses	FEC0: 1/1024th of all available IPv6 Space, its sort of Private IP Addressing Scheme. Deprecated.
Multicast Addresses	FFxx: Starts with FF, used for Multicasting.
Multicast to all hosts	FF02::1 essentially the same as 255.255.255.255

1. The Broadcast has been removed, multicasting has taken its place.
2. FrameRelay Inverse-Arp is not yet implemented, so Static Mapping should be used.
3. ICMPv6 Neighbor Discovery will ultimately replace IPv4 ARP.

ICMPv6 Neighbor Solicitation	Ask for Information about the neighbor
ICMPv6 Neighbor Advertisement	Advertise yourself to neighbor
ICMPv6 Router Solicitation	Ask for info about the Local Routers
ICMPv6 Router Advertisement	Advertise yourself as Local Router

4. Ipv6 unicast-routing enables IPv6 on a Router. It enables ICMPv6 ND and Dynamic Routing Support.
5. Debug ipv6 packet detail
6. Debug ipv6 nd

RIPng

RFC 2080 Defines Ripng for IPv6

UDP Port 521 is used instead of 520 with a Multicast Address of FF02::9

Configuration:

Interface Level : Ipv6 rip [process] enable

OSPFv3

7. Similar to OSPFv2
8. Router-id is an IPv4 Address
9. Configuration:
10. Interface Level: ipv6 ospf [process id] area [area-id]
11. Global Level: Automatically Enabled.
12. Multicast Address is: FF02::5

BGPv6

13. Same process for IPv6 as of IPv4.
14. Address-family configuration is used.

Static Tunneling:

15. GRE	The Default Tunnel Mode
    IPv6 IP	Running IPv4 to IPv6 Tunneling

Automatic Tunnels:

16. 6to4 Tunnels	IPv6 Address to IPv4 Tunneling
    ISATAP	Automatic Host to Host or Host to Router Tunneling
