Configuring IPv6
Overview
IPv6 is the next generation of the Internet Protocol. With 128-bit addresses, versus 32-bit addresses
for IPv4, IPv6 solves the address depletion issues seen with IPv4 and removes the requirement for
Network Address Translation (NAT), which is used in IPv4 networks to reduce the number of
globally unique IP addresses required for a given network. Its aggregate addresses can dramatically
reduce the size of the global routing table through well known address combinations. Security is
more integrated and network configuration is simplified yet more flexible.
On the PowerConnect M6220/M6348/M8024, IPv6 coexists with IPv4. As with IPv4, IPv6 routing
can be enabled on loopback and VLAN interfaces. Each L3 routing interface can be used for IPv4,
IPv6, or both. IP protocols running over L3 (for example, UDP and TCP) do not change with IPv6.
For this reason, a single CPU stack is used for transport of both IPv4 and IPv6, and a single sockets
interface provides access to both. Routing protocols are capable of computing routes for one or both
IP versions.
The IPv6

•OSPFv3
•IPv6 Routes
Note: CLI commands are not available for all the IPv6 pages.
