How do I set up a 6in4 tunnel?
How do I set up a 6in4 tunnel?
Configure switch C
- Configure the Tunnel Endpoint for Switch C.
- Configure VLAN 2 for the IPv6 Hosts on the 4000::/64 Network.
- Configure IPv6 Routing to Route into the Tunnel.
- Configure the VLAN Used to Reach the First Hop Router in the IPv4 Network.
- Configure the IPv4 Default Gateway.
How does IPv6 tunnel work?
IPv6 Tunneling allows hosts in one private IP network to communicate with hosts in another private IP network by providing a tunnel between two routers across the Internet. The IPv6 tunnel connection endpoints are terminated via a Virtual Tunnel Interface (VTI) configured in each device.
How do I configure IPv6 tunneling over IPv4?
How to Configure IPv6 Over IPv4 Tunnels
- Add the tunnel source addresses. Then, add the tunnel destination addresses. tsrc IPv4-source-addr tdst IPv4-destination-addr up.
- (Optional) Add a logical interface for the source and destination IPv6 addresses. addif IPv6-source-address IPv6-destination-address up.
What is the purpose of 6 to 4 technology?
The Solaris operating system includes 6to4 as a preferred interim method for making the transition from IPv4 to IPv6 addressing. 6to4 enables isolated IPv6 sites to communicate across an automatic tunnel over an IPv4 network that does not support IPv6.
How IPv4 and IPv6 tunnels work?
IPv6 over IPv4 tunnels are point-to-point tunnels made by encapsulating IPv6 packets within IPv4 headers to carry them over IPv4 routing infrastructures. An IPv6 over IPv4 tunnel allows IPv6 packets to be transmitted on an IPv4 network and connects all IPv6 sites.
How does IPv4 tunneling work?
Automatic tunnels require IPv4–compatible addresses. Automatic tunnels can be used to connect IPv6 nodes when IPv6 routers are not available. These tunnels work by dynamically determining the destination IPv4 address, the endpoint of the tunnel, by extracting the address from the IPv4–compatible destination address.
What port does 6to4 use?
Some IPv6 tunnels with the use of NetFlow to detect protocol 41 (this is protocol and not UDP/TCP port) or UDP port 3544 (which is the default Teredo UDP port) or traffic to 192.88. 99.1 (which is the default anycast address of 6to4 relays).
What is an IPv4 6to4 tunnel?
In automatic 6to4 tunnels, the IPv4 infrastructure is treated as a virtual nonbroadcast multiaccess (NBMA) link routers are not configured as point-to-point. The IPv4 address embedded in the IPv6 address is used to find the other end of the automatic tunnel.
What is the difference between 6to4 and IPv6?
A relay router connects to an IPv4 network and an IPv6 network. 6to4 packets arriving on an IPv4 interface will have their IPv6 payloads routed to the IPv6 network, while packets arriving on the IPv6 interface with a destination address prefix of 2002::/16 will be encapsulated and forwarded over the IPv4 network.
What is the difference between manual tunnels and automatic 6to4 tunnels?
The main difference between the manual tunnels and automatic 6to4 tunnels is that the tunnel is not point-to-point but it is point-to-multipoint. In automatic 6to4 tunnels, the IPv4 infrastructure is treated as a virtual nonbroadcast multiaccess (NBMA) link routers are not configured as point-to-point.
What is the default IPv6 default gateway for a 6to4 host?
To allow a 6to4 host to communicate with the native IPv6 Internet, it must have its IPv6 default gateway set to a 6to4 address which contains the IPv4 address of a 6to4 relay router. To avoid the need for users to set this up manually, the anycast address 192.88.99.1 used to be allocated.
