Introduction to IPv6


IPv6 Address

IPv432 bits= 4,294,967,296 possible addressable devices

IPv6128 bits: 4 times the size in bits= 3.4 x 1038 possible addressable devices= 340,282,366,920,938,463,463,374,607,431,768,211,456∼ 5 x 1028 addresses per person on the planet


IPv6 Address


IPv6 Global Unicast Addresses


IPv6 Address Allocation


Interface ID Assignment• Lowest-order 64-bit field of unicast addresses may be assigned in

several different ways

Manually configured

Stateless configuration

Assigned via DHCP

Auto-generated pseudo-random number (rfc3041)

DHCPv6 Request

Introduction Routing in IPv6


Routing in IPv6


Static Routing

Router(config)# ipv6 route ipv6-prefix/prefix-length {ipv6-address| interface-type interface-number [ipv6-address]} [administrativedistance][administrative-multicast-distance | unicast|multicast] [tag tag]

Router1(config)#ipv6 route 2002:0:1:3::/64 2002:0:1:2::2RouterA(config)#ipv6 route ::/0 serial1/0


RIPng for IPv6

Router(config)#ipv6 router rip process

Router(config-rtr)#interface type number

Router(config-if)#ipv6 rip process enable


OSPFv3 configuration example


OSPFv3 on IPV6 Tunnels over IPv4


BGP Configurations Non Link Local Peering


BGP Configurations Filtering Prefixes


Tunneling


Tunnels for IPv6 Deployment

� Tunneling is encapsulating the IPv6 packet into an IPv4 packet

Host to Router, Router to RouterRouter to Host, Host to Host

� Manually configured tunnels

Manual Tunnel (RFC 2893)

IPv6 over GRE (RFC 2473)

� Semi-automated tunnels

Tunnel broker (RFC 3053)

� Automatic tunnels

6to4 (RFC 3056)

ISATAP

Dynamic Multipoint VPN (DMVPN)


IPv6 over IPv4 Tunnels


Manually Configured Tunnels (RFC2893)


6to4 Tunnel ( RFC 3056 )
