IPv6 Tunnels

Automatic 6to4 Tunnel

Tunnel format

2002(16 bits) + IPv4 address(32 bits) + Subnet(16 bits) + Interface ID(64 bits)

First 16 bits of 6to4 tunnel always starts with 2002.
Tunnel is point-to-multipoint in nature.
IPv4 address bits are written in HEX value here, for example, 1.1.1.1 = 0101:0101
When routed a packet through the tunnel, router looks at the IPv4 bits portion and forwards to the appropriate destination router.

IPv6 Routing with OSPFv3(Summarization and virtual-link)

In this lab, R4 will announce 2001:4::4/128 prefix into area 24.
When the advertisment reach ABR(R2) of area 24, R2 will summarize it into /64.
Likewise, R1 is also redistributing 2001:1::1/128 route into OSPF domain, since R1 is the ASBR itself, we can summarize it on R1. In this case, we will summarize it into /64.
R3 is not connecting to backbone area, R3 is announcing 2001::3/128 into area 3. The advertisement cannot reach to the rest of the OSPF domain.
In order to reach every other routers, R3 needs to be connected to backbone area which is area 0, so we will build virtual link between R1 and R3 to extend the backbone area to R3.
