IPv6 over IPv4 tunnels in hardware

To enable communication between the isolated IPv6 domains using the IPv4 infrastructure, you
can configure IPv6 over IPv4 tunnels.
Brocade supports the following IPv6 over IPv4 tunneling in hardware mechanisms:
•
In general, a manually configured tunnel establishes a permanent link between routers in IPv6
domains. A manually configured tunnel has explicitly configured IPv4 addresses for the tunnel
source and destination.
This tunneling mechanism requires that the router at each end of the tunnel run both IPv4 and IPv6
protocol stacks. The routers running both protocol stacks, or dual-stack routers, can interoperate
directly with both IPv4 and IPv6 end systems and routers.
Configuring a manual IPv6 tunnel
You can use a manually configured tunnel to connect two isolated IPv6 domains. You should deploy
this point-to-point tunnel mechanism if you need a permanent and stable connection.

NOTE
IPV6 over IPV4 tunnel will not work when used with transperant VLAN flooding mode .

To configure a manual IPv6 tunnel, enter commands such as the following on a Layer 3 Switch
running both IPv4 and IPv6 protocol stacks on each end of the tunnel.

Manually configured tunnels
The tunnel mode should be ipv6ip indicating that this is ipv6 manual tunnel
Both source and destination addresses needs to be configured on the tunnel.
On the remote side we need to have exactly opposite source or destination pair.
The tunnel destination should be reachable through the ipv4 backbone.
The ipv6 address on the tunnel needs to be configured for the tunnel to come up
Both static and dynamic IPv6 routing protocols on top of the tunnel are supported
The tunnel source can be ip address or interface name
Manual tunnels provide static point-point connectivty
