Dell™ PowerConnect™ 6200 Series User's Guide
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 (NATs), 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 6200 Series, 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 menu page contains links to the following features:

Use the Interface Configuration page to configure IPv6 interface parameters.
To display the page, click IPv6® Interface Configuration in the tree view.
Figure 11-2. IPv6 Interface Configuration
The IPv6 Interface Configuration page contains the following fields:
Interface — Selects the interface to be configured. When the selection is changed, a screen refresh occurs, causing all fields to be updated for the newly selected port. Shows only routing-enabled interfaces and tunnels.
IPv6 Mode — When IPv6 mode is enabled, interface is capable of IPv6 operation without a global address. In this case, an EUI-64 based link-local address is used. This selector lists the two options for IPv6 mode: Enable and Disable. Default value is Disable.
IPv6 Prefix — Choose to Add or Delete an IPv6 prefix on this interface. If adding a prefix, specify that prefix in the following IPv6 Prefix field. Clicking Delete causes deletion of a displayed IPv6 Prefix.
IPv6 Prefix — Specifies the IPv6 prefix with prefix length for an interface. When the selection is changed, the screen is refreshed and valid lifetime, preferred lifetime, on-link flag, and autonomous flag updated for selected IPv6 address.
EUI-64 — If checked, specifies 64-bit unicast prefix.
Valid Lifetime by Prefix — The value, in seconds, to be placed in the Valid Lifetime field of the Prefix Information option in a router advertisement. The prefix is valid for on-link determination for this length of time. Hosts that generate an address from this prefix using stateless address auto-configuration can use those addresses for this length of time. An auto-configured address older than the preferred lifetime but younger than the valid lifetime are considered "deprecated addresses." As defined by RFC 2462, a deprecated address is "An address assigned to an interface whose use is discouraged, but not forbidden. A deprecated address should no longer be used as a source address in new communications, but packets sent from or to deprecated addresses are delivered as expected. A deprecated address may continue to be used as a source address in communications where switching to a preferred address causes hardship to a specific upper-layer activity (for example, an existing TCP connection)." The valid range is from 0 to 4,294,967,295 seconds.
Preferred Lifetime by Prefix — The value, in seconds, to be placed in the Preferred Lifetime in the Prefix Information option in a router advertisement. Addresses generated from a prefix using stateless address autoconfiguration remain "preferred" for this length of time. As defined by RFC 2462, a preferred address is "an address assigned to an interface whose use by upper layer protocols is unrestricted. Preferred addresses may be used as the source (or destination) address of packets sent from (or to) the interface." The range is from 0 to 4,294,967,295 seconds.
Onlink Flag by Prefix — Specifies the selected prefix that can be used for on-link determination. Default value is Enable. This selector lists the two options for on-link flag: Enable and Disable.
Autonomous Flag by Prefix — Specifies the selected prefix that can be used for autonomous address configuration. Default value is Disable. This selector lists the two options for autonomous flag: Enable and Disable.
Current State by Prefix — Interface Operational status for selected IPv6 prefix.
Routing Mode — Specifies the routing mode of an interface. This selector lists the two options for routing mode: Enable and Disable. Default value is Disable.
IPv6 Routing Operational Mode — Specifies the operational state of an interface. Default value is Disable.
Interface Maximum Transmit Unit — Specifies the maximum transmit unit on an interface. If the value is 0 then this interface is not enabled for routing. It is not valid to set this value to 0 if routing is enabled. The valid range of MTU is 1280 to 1500.
Router Duplicate Address Detection Transmits — Specifies the number of duplicate address detections transmits on an interface. DAD transmits values must be in the range of 0 to 600.
Router Advertisement NS Interval — Specifies retransmission time field of router advertisement sent from the interface. A value of 0 means the interval is not specified for this router. The range of neighbor solicit interval is 1000 to 4294967295.
Router Lifetime Interval — Specifies the router advertisement lifetime field sent from the interface. This value must be greater than or equal to the maximum advertisement interval. 0 means do not use the router as the default router. The range of router lifetime is 0 to 9000.
Router Advertisement Reachable Time — Specifies the router advertisement time to consider neighbor reachable after the neighbor discovery (ND) confirmation. The range of reachable time is 0 to 3600000.
Router Advertisement Interval — Specifies the maximum time allowed between sending router advertisements from the interface. The default value is 600. the range of maximum advertisement interval is 4 to 1800.
Router Advertisement Managed Config Flag — Specifies the router advertisement managed address configuration flag. When true, the end nodes use DHCPv6. When false, the end nodes auto configure the addresses. The default value of managed flag is Disable.
Router Advertisement Other Config Flag — Specifies the router advertisement other stateful configuration flag. The default value of other config flag is Disable.
Router Advertisement Suppress Flag — Specifies the router advertisement suppression on an interface. The default value of suppress flag is Disable.
The IPv6 interface modifications are saved, and the device is updated.

IPv6 Statistics
Total Datagrams Received — The total number of input datagrams received by the interface, including those received in error.
Received Datagrams Locally Delivered — The total number of datagrams successfully delivered to IPv6 user-protocols (including ICMP). This counter is incremented at the interface to which these datagrams were addressed, which might not be necessarily the input interface for some of the datagrams.
Received Datagrams Discarded Due To Header Errors — The number of input datagrams discarded due to errors in their IPv6 headers, including version number mismatch, other format errors, hop count exceeded, errors discovered in processing their IPv6 options, etc.
Received Datagrams Discarded Due To MTU — The number of input datagrams that could not be forwarded because their size exceeded the link MTU of outgoing interface.
Received Datagrams Discarded Due To No Route — The number of input datagrams discarded because no route could be found to transmit them to their destination.
Received Datagrams With Unknown Protocol — The number of locally-addressed datagrams received successfully but discarded because of an unknown or unsupported protocol. This counter is incremented at the interface to which these datagrams were addressed which might not be necessarily the input interface for some of the datagrams.
Received Datagrams Discarded Due To Invalid Address — The number of input datagrams discarded because the IPv6 address in their IPv6 header's destination field was not a valid address to be received at this entity. This count includes invalid addresses (for example, ::0) and unsupported addresses (for example, addresses with unallocated prefixes). For entities which are not IPv6 routers and therefore do not forward datagrams, this counter includes datagrams discarded because the destination address was not a local address.
Received Datagrams Discarded Dut To Truncated Data — The number of input datagrams discarded because datagram frame didn't carry enough data.
Received Datagrams Discarded Other — The number of input IPv6 datagrams for which no problems were encountered to prevent their continued processing, but which were discarded (for example, for lack of buffer space). Note that this counter does not include any datagrams discarded while awaiting re-assembly.

Datagrams Failed To Reassemble — The number of failures detected by the IPv6 reassembly algorithm (for whatever reason: timed out, errors, etc.). Note that this is not necessarily a count of discarded IPv6 fragments since some algorithms (notably the algorithm in RFC 815) can lose track of the number of fragments by combining them as they are received. This counter is incremented at the interface to which these fragments were addressed which might not be necessarily the input interface for some of the fragments.
Datagrams Forwarded — The number of output datagrams which this entity received and forwarded to their final destinations. In entities which do not act as IPv6 routers, this counter includes only those packets which were Source-Routed through this entity, and the Source-Route processing was successful. Note that for a successfully forwarded datagram the counter of the outgoing interface is incremented.
Datagrams Locally Transmitted — The number of datagrams which this entity has successfully transmitted from this output interface.
Datagrams Transmit Failed — The number of datagrams which this entity failed to transmit successfully.
Datagrams Successfully Fragmented — The number of IPv6 datagrams that have been successfully fragmented at this output interface.

DHCP is generally used between clients (for example hosts) and servers (for example routers) for the purpose of assigning IP addresses, gateways, and other networking definitions such as DNS, NTP, and/or Session Initiation Protocol (SIP) parameters. However, IPv6 natively provides for auto configuration of IP addresses through IPv6 Neighbor Discovery Protocol (NDP) and the use of Router Advertisement messages. Thus, the role of DHCPv6 within the network is different than that of DHCPv4 in that it is less relied upon for IP address assignment.
There is a list of DHCP options that is commonly supported by DHCPv4 and that need to be supported also by DHCPv6, and must be configured.

OSPFv3 is the Open Shortest Path First routing protocol for IPv6. It is similar to OSPFv2 in its concept of a link state database, intra/inter area, and AS external routes and virtual links. It differs from its IPv4 counterpoint in a number of respects, including the following: peering is done through link-local addresses; the protocol is link rather than network centric; and addressing semantics have been moved to leaf LSAs, which eventually allow its use for both IPv4 and IPv6. Point to point links are also supported in order to enable operation over tunnels.
It is possible to enable OSPF and OSPFv3 at the same time. OSPF works with IPv4 and OSPFv3 works with IPv6.
The OSPFv3 menu page contains links to web pages that define and display OSPFv3 parameters and data. To display this page, click IPv6® OSPFv3 in the tree view.
Following are the web pages accessible from this menu page:
Use the OSPFv3 Configuration page to activate and configure OSPFv3 for a switch.
To display the page, click IPv6® OSPFv3® Configuration in the tree view.
Figure 11-16. OSPFv3 Configuration
The OSPFv3 Configuration page contains the following fields:
Router ID — The 32-bit integer in dotted decimal format that uniquely identifies the router within the autonomous system (AS). If you want to change the Router ID you must first disable OSPFv3. After you set the new Router ID, you must re-enable OSPFv3 to have the change take effect. The default value is 0.0.0.0, although this is not a valid Router ID, and must be changed before you press the Apply Changes button.
OSPFv3 Admin Mode — Select Enable or Disable from the drop-down menu. If you select Enable, OSPFv3 is activated for the switch. The default value is Enable. You must configure a Router ID before OSPFv3 becomes operational. This can also be done by issuing the CLI command, router-id, in the IPv6 router OSPF mode.
|
|
NOTE: Once OSPFv3 is initialized on the router, it remains initialized until the router is reset. |
ASBR Mode — Reflects whether the ASBR mode is enabled or disabled. Enable implies that the router is an autonomous system border router. Router automatically becomes an ASBR when it is configured to redistribute routes learnt from other protocol.
ABR Status — The values of this are Enable or Disable. The field displays only when a valid configuration exists. Enabled implies that the router is an area border router. Disabled implies that it is not an area border router.
Exit Overflow Interval (secs) — Enter the number of seconds that, after entering overflow state, the router should wait before attempting to leave overflow state. This allows the router to again originate non-default AS-external-LSAs. If you enter 0, the router does not leave Overflow State until restarted. The range is 0 to 2147483647 seconds.
External LSA Count — The number of external (LS type 5) LSAs (link state advertisements) in the link state database.
External LSA Checksum — The sum of the LS checksums of the external LSAs (link state advertisements) contained in the link-state database. This sum can be used to determine if there has been a change in a router's link state database, and to compare the link-state databases of two routers.
New LSAs Originated — In any given OSPFv3 area, a router originates several LSAs. Each router originates a router-LSA. If the router is also the Designated Router for any of the area's networks, it originates network-LSAs for those networks. This value represents the number of LSAs originated by this router.
LSAs Received — The number of LSAs (link state advertisements) received that were determined to be new instantiations. This number does not include newer instantiations of self-originated LSAs.
External LSDB Limit — The maximum number of AS-External-LSAs that can be stored in the database. A value of -1 implies there is no limit on the number that can be saved. The valid range of values is -1 to 2147483647.
Default Metric — Sets a default for the metric of redistributed routes. This field displays the default metric if one has already been set or blank if not configured earlier. Valid values are 1 to 16777214.
Maximum Paths — Configure the maximum number of paths that OSPFv3 can report to a given destination. Valid values are 1 to 2.
Default Information Originate — Enable or disable Default Route Advertise. Note that the values for Always, Metric, and Metric Type can only be configured after Default Information Originate is set to Enable. If Default Information Originate is set to Enable and values for Always, Metric, and Metric Type are already configured, then setting Default Information Originate back to disable sets the Always, Metric, and Metric Type values to default.
Always — Sets the router advertise ::/0 when set to True.
