IPv6 on vRacks

Do you guys have the IPv6 RA DoS vs windows boxes protected against?

Hello everyone,

Now, you have a /56 block of IPv6 in each virtual rack. In
addition, you can configure the reverses or manage directly
the reverse zone.

The IPv6 block is automatically configured if you have an IPv4
block. Also, if you use a virtual rack only as a
private network, you won't have IPv6 (so to guarantee the
privacy precisely...).

To find out the IPv6 block and the network parameters for it, go
to the manager and select the virtual rack infrastructure in the list.

Some other notes:

IPv6 is not yet available for the ACE and the firewall on the
virtual racks.

The router doesn't announce the Remote Advertisement so
you can allocate your address block automatically. If you
want that, you can put in place a RA or DHCPv6 dameon
in your vlan.

As with IPv4, IPv6 routing is redundant (HSRP + OSPF)
between the routers rbx-s1 and rbx-s2 (hence the 2 IP
before the gateway IP are reserved and should never
be used).

The first IP in the subnet and 128 first IPs are normally
reserved (anycast).
