1 IPv6 Configuration Guide
This document describes the IPv6 features and configurations supported by Supermicro Layer 2 / Layer 3
switches.
The majority of this document applies to the above listed Supermicro switch products. In any particular
subsection however, the contents might vary across these product models. In those sections the
differences are clearly identified with reference to a particular model(s). If any particular model is not
referenced, the reader can safely assume that the content is applicable to all the above listed models.
Throughout this document, the common term “switch” refers to any of the above listed
Supermicro switch models unless a particular model is noted.
1.1 IPv6 Overview
IPv6 is designed to replace IPv4, providing an increase in the number of network address bits from 32 to
128 bits. IPv6 is based on IPv4, however IPv6 has a much larger address space and simplified main
header and extension headers.
The large IPv6 address space enablesextends network scalability and global reachability. The simplified
IPv6 packet header format handles packets more efficiently. The flexibility of the IPv6 address space
reduces the need for private addresses and the use of Network Address Translation (NAT), which
translates private (not globally unique) addresses into a limited number of public addresses.

IPv6 functionality like prefix aggregation, simple network renumbering and site multihoming capabilities,
enable efficient routing. IPv6 in Supermicro switches supports Routing Information Protocol (RIP), Open
Shortest Path First (OSPF) for IPv6, and Protocol Independent Multicast-Sparse Mode (PIM-SM).
1.1.1 IPv6 Addresses
IPv6 addresses are denoted by eight groups of hexadecimal quartets separated by colons. Any four-digit
group of zeroes within an IPv6 address may be reduced to a single zero or omitted altogether.
For example,
2001:cdba:0000:0000:0000:0000:3257:9652
2001:cdba:0:0:0:0:3257:9652
2001:cdba::3257:9652
Parts of an IPv6 Address
X : X : X : X : X : X : X : X
X : X : X – First 3 Hexadecimal numbers represent Prefix
X : X – Next 2 Hexadecimal numbers represents Subnet ID
X : X : X – Last 3 Hexadecimal numbers represent Interface ID
1.1.1.1 IPv6 Address Types
IPv6 addresses are broadly classified into three categories:
1) Unicast addresses: A Unicast address is an identifier for a single interface. An IPv6 packet sent to a
Unicast address is delivered to the interface identified by that address.
2) Multicast addresses: A Multicast address is an identifier for a group/set of interfaces that belongs to
different nodes. An IPv6 packet delivered to a Multicast address is delivered to the multiple interfaces.
3) Anycast addresses: Anycast address is an identifier for a set of interfaces that may belong to the
different nodes. An IPv6 packet destined for an Anycast address is delivered to one of the interfaces
identified by the address.

Local Addresses
These addresses are used on a
single link or a non-routed
common access network, such as
an Ethernet LAN.
Link-local addresses may appear
as the source or destination of
an IPv6 packet. Routers must not
forward IPv6 packets if the
source or destination contains a
link-local address.

1.1.2 IPv6 Header
The IPv6 header format is similar to IPv4 header fields. Even though IPv6 addresses are four times longer
than IPv4 addresses, the IPv6 header is only twice the size of the IPv4 header.
The IPv6 packet header has 8 fields with a size of 40 octets (320 bits). Fragmentation is handled by the
source of a packet and checksums at the data link layer and transport layer.

Version
Similar to
the
IPv4 packet header, except that the field lists number
6 for IPv6 instead of number 4 for IPv4.
Traffic Class
Similar to
the
IPv4 packet header. The Traffic Class
field tags packets
with a traffic class that is used in differentiated services.
Flow Label
New field in the IPv6 packet header. The Flow Label field tags
packets with a specific flow that differentiates the packets at the
network layer.

Payload Length field indicates the total length of the data portion of
the packet.
Next Header
Similar to
the
IPv4 packet header. The value of the Next Header field
determines the type of information following the basic IPv6 header
,
for example, a TCP or UDP packet or an Extension header.
Hop Limit
Similar to
the
Time to Live field in the IPv4 packet header. The value
of the Hop Limit field specifies the maximum number of routers th
at
an IPv6 packet can pass through before the packet is considered
invalid. Each router decrements the value by one. Because no
checksum is in the IPv6 header, the router can decrement the value
without needing to recalculate the checksum, which saves
processing resources.
Source
Address
Similar to the Source Address field in the IPv4 packet header, except
that this contains a 128-bit source address for IPv6.
Destination
Address
Similar to the Destination Address field in the IPv4 packet header,
except that the field contains a 128-bit destination address for IPv6.
Following the basic IPv6 packet header are optional extension headers and the data portion of the
packet. If present, each extension header is limited to 64 bits. There is no limit to the number of
extension headers in an IPv6 packet. Each extension header is identified by the Next Header field of the
previous header.
The extension header types and their Next Header field values are mentioned in the table below.

17 (UDP)
Headers inside a packet to transport the data. The two
main transport protocols are TCP and UDP.
1.1.3 IPv6 Tunnel
Because most networks use the IPv4 protocol, IPv6 networks currently require a way to communicate
outside their borders. IPv6 networks use tunnels for this purpose. In most IPv6 tunneling scenarios, the
outbound IPv6 packet is encapsulated inside an IPv4 packet. The boundary router of the IPv6 network
sets up a point-to-point tunnel over various IPv4 networks to the boundary router of the destination
IPv6 network. The packet travels over the tunnel to the destination network's boundary router, which
decapsulates the packet. Then, the router forwards the separate IPv6 packet to the destination node.
1.1.4 Neighbor Discovery Protocol
Neighbor Discovery permits nodes on the same link to advertise their existence to their neighbors and
to learn about the existence of their neighbors. Neighbor Discovery is built on top of Internet Control
Message Protocol version 6 (ICMPv6).
Neighbor Discovery uses router advertisement messages to detect neighbors, advertise IPv6 prefixes,
address provisioning, and share link parameters such as MTU, hop limit, advertisement intervals, and
lifetime.
Neighbor Discovery uses the following message types:
Router Advertisement (RA) —Messages sent to announce the presence of the router, advertise prefixes,
assist in address configuration, and share other link information such as MTU size and hop limit. The
IPv6 nodes on the link can use this information to configure themselves with an IPv6 address and
routing information such as the default gateway.
Router Solicitation (RS)—Messages sent by IPv6 nodes when they come online to solicit immediate
router advertisements from the router.
Neighbor Solicitation (NS)—Messages used for duplicate address detection and to test the reachability
of neighbors. A host can verify that its address is unique by sending a neighbor solicitation message
destined to the new address. If the host receives a neighbor advertisement in reply, the address is a
duplicate.
Neighbor Advertisement (NA)—Messages used for duplicate address detection and to test the
reachability of neighbors. Neighbor advertisements are sent in response to neighbor solicitation
messages.
Supermicro L2/L3 Switches Configuration Guide
11
Redirect Routers use redirect messages to inform hosts of a better first hop for a destination, or that
the destination is on the same link.
1.1.4.1 Router Advertisement (RA)
Each router periodically sends to the multicast group a router advertisement packet that announces its
availability. This is applicable only on multicast-capable links and point-to-point links routers generate
router advertisements frequently so hosts learn of their neighbors within a few minutes.
Router advertisement messages also contain parameters such as the hop limit and link MTU. This
feature enables the centralized administration of critical parameters since parameters are set on routers
and propagated to all attached hosts.
1.1.4.2 Neighbor Solicitation
Neighbor solicitation messages determine if more than one node is assigned the same unicast address.
Neighbor unreachability detection detects the failure of a neighbor or the failure of the forward path to
the neighbor. This detection requires positive confirmation that the packets that are sent to a neighbor
are actually reaching that neighbor.
Neighbor unreachability detection uses confirmation from two sources: upper-layer protocols and
neighbor solicitation messages. When possible, upper-layer protocols provide a positive confirmation
that a connection is making forward progress. For example, when new TCP acknowledgments are
received, it is confirmed that previously sent data has been delivered correctly.
When a node does not receive positive confirmation from upper-layer protocols, the node sends unicast
neighbor solicitation messages. These messages solicit neighbor advertisements as reachability
confirmation from the next hop.
1.1.4.3 Duplicate Address Detection
Duplicate address detection is performed on a new link-local IPv6 address before the address is assigned
to an interface:
A node sends a neighbor solicitation message with an unspecified source address and a
tentative link-local address in the body of the message.
If another node is already using that address, the node returns a neighbor advertisement
message that contains the tentative link-local address.
If another node is simultaneously verifying the uniqueness of the same address, that node also
returns a neighbor solicitation message.
If no neighbor advertisement messages are received in response to the neighbor solicitation
message and no neighbor solicitation messages are received from the other nodes that are
attempting to verify the same tentative address, the node that sent the original neighbor
Supermicro L2/L3 Switches Configuration Guide
12
solicitation message considers the link-local address to be unique and assigns the address to the
interface.
1.1.4.4 RA Prefixes
Router advertisements contain subnet prefixes, which are used to determine if a host is on the same link
(on-link) as the router. Hosts use the advertised prefixes to build and maintain a list that is used to
decide when a packet's destination is on-link or beyond a router.
Router advertisements and per-prefix flags provide stateless address auto configuration.
1.1.4.5 Stateless Autoconfiguration
All interfaces on IPv6 nodes have a link-local address on startup, which is usually automatically
configured from the identifier for an interface and the link-local prefix FE80::/10. A link-local address
enables a node to communicate with other nodes on the link and can be used to further configure the
node.
Nodes can connect to a network and automatically generate global IPv6 addresses without the need for
manual configuration or the help of a server such as a Dynamic Host Configuration Protocol (DHCP)
server.
1.1.4.6 Timers
Supermicro switches enable the configuration of the following Neighbor Discovery timers:
Router Advertisement Interval
By default, router advertisements are sent out every 200 seconds. Supermicro allows user to
change the interval between router advertisement transmissions on an interface.
Neighbor Reachable Time
The neighbor reachable time enables the detection of unavailable neighbors. Shorter configured
times enable detecting unavailable neighbors more quickly, however, this consumes more
network bandwidth and processing resources in all IPv6 network devices. Very short configured
times are not recommended in normal IPv6 operations.
Router Lifetime
The router lifetime value specifies how long nodes on the local link should consider the switch as
the default router on the link.
Supermicro L2/L3 Switches Configuration Guide
13
Retransmit Time
The retransmission timer is used to control the time between retransmissions of neighbor
solicitation messages.
1.1.4.7 Hop Limit
The Hop Limit field specifies the maximum number of routers that an IPv6 packet can pass through
before the packet is considered invalid. Each router decrements the value by one. Because no checksum
is in the IPv6 header, the router can decrement the value without needing to recalculate the checksum,
which saves processing resources
.
1.1.4.8 Static Neighbor
Supermicro provides manual configuration of a neighbor in the IPv6 neighbor cache. If an entry for the
specified IPv6 address already exists in the neighbor discovery cache (learned through the IPv6 neighbor
discovery process) the entry is automatically converted to a static entry. Static entries in the IPv6
neighbor discovery cache are not modified by the neighbor discovery process.

The command no ipv6 nd dad attemptsresets the duplicate address detection attempts
to its default value of 1.
The command no ipv6 nd reachable-time resets the advertised reachability time to its
default value of 30.
The command no ipv6 nd retrans-time” resets the advertised retransmit time to its default
value of 1.
The command no ipv6 nd ra-intervalresets the IPv6 router advertisement interval to its
default value of 600.
The command “no ipv6 nd prefix {<prefix addr> <prefix len> | default}” removes the prefix
from the IPv6 router advertisement.
1.2.4 Configuration Example
The example below shows the commands used to enable IPv6 between two switches switch A and
switch B.
Configuration on switch A
SMIS# configure terminal
SMIS(config)# vlan 10
