Configuring basic IPv6 connectivity on a Layer 3 switch
5
The eui-64 keyword configures the global address with an EUI-64 interface ID in the low-order 64
bits. The interface ID is automatically constructed in IEEE EUI-64 format using the interface MAC
address.
Configuring a link-local IPv6 address on an interface
To explicitly enable IPv6 on a router interface without configuring a global or site-local address for
the interface, enter commands such as the following.
PowerConnect(config)# interface ethernet 1
PowerConnect(config-if-e10000-1)# ipv6 enable
These commands enable IPv6 on Ethernet interface 1 and specify that the interface is assigned an
automatically computed link-local address.
Syntax: [no] ipv6 enable
NOTE
When configuring VLANs that share a common tagged interface with a physical or Virtual Ethernet
(VE) interface, Dell recommends that you override the automatically computed link-local address
with a manually configured unique address for the interface. If the interface uses the automatically
computed address, which in the case of physical and VE interfaces is derived from a global MAC
address, all physical and VE interfaces will have the same MAC address.
To override a link-local address that is automatically computed for an interface with a manually
configured address, enter commands such as the following.
PowerConnect(config)# interface ethernet 1
PowerConnect(config-if-e10000-1)# ipv6 address FE80::240:D0FF:FE48:4672
link-local
These commands explicitly configure the link-local address FE80::240:D0FF:FE48:4672 for
Ethernet interface 1.
Syntax: ipv6 address ipv6-address link-local
You must specify the ipv6-address parameter in hexadecimal using 16-bit values between colons
as documented in RFC 2373.
The link-local keyword indicates that the router interface should use the manually configured
link-local address instead of the automatically computed link-local address.
Configuring an IPv6 anycast address on an interface
In IPv6, an anycast address is an address for a set of interfaces belonging to different nodes.
Sending a packet to an anycast address results in the delivery of the packet to the closest interface
configured with the anycast address.
An anycast address looks similar to a unicast address, because it is allocated from the unicast
address space. If you assign an IPv6 unicast address to multiple interfaces, it is an anycast
address. On the PowerConnect device, you configure an interface assigned an anycast address to
recognize the address as an anycast address.
For example, the following commands configure an anycast address on interface 1.
PowerConnect(config)# int e 1
PowerConnect(config-if-e10000-1)# ipv6 address 2002::/64 anycast
Syntax: ipv6 address ipv6-prefix / prefix-length [ anycast ]
