vRouter, or router in the guide).

IPv6 Support Overview

IPv6 .14

Commands 14

IPv6 background

There are two versions of the Internet Protocol (IP) in use today. Version 4 (IPv4) is the version most commonly in use. However, there

are issues with IPv4, and the Internet Engineering Task Force (IETF) has designated Version 6 (IPv6) to succeed IPv4 as the next-

generation protocol for use on the Internet.

IPv6 has a number of advantages over IPv4. The following are four important ones:

•Large address space

An IPv4 address consists of four bytes (32 bits). IPv6 addresses consist of 16 bytes (128 bits). The increase from 32 to 128

bits results in a huge increase in the number of available addresses: 79 billion billion billion times the addresses available in the

IPv4—this is about 1038 addresses, or 1030 addresses for each person on the planet.

The expanded address space means that IPv6 does not face the address exhaustion problems predicted imminently for IPv4.

Furthermore, the availability for so many addresses means that private address spaces are not required, and that address

shortage work-arounds such as Network Address Translation (NAT) can be eliminated. With no private addresses, there need be

no hidden networks or hosts, and all devices can be globally reachable. A larger address space also means that features such as

multihoming and aggregation are easier to implement.

•Support for mobile devices

A special protocol, Mobile IP, is required to support mobility. Mobile IP is not automatic in IPv4, and there are several challenges

involved in implementing Mobile IP on IPv4 networks. In contrast, Mobile IP was designed into IPv6 from its inception, and is a

mandatory feature in a standards-compliant IPv6 protocol stack.

•Flexibility

IPv6 includes multiple levels of hierarchy in the address space. This allows for hierarchical allocation of addressing and more

efficient route aggregation. It also permits new kinds of addresses not possible in IPv4, such as link- and site-scoped

addressing.

•Security

Because devices can be globally reachable, end-to-end security can be employed, which is not possible on an internetwork with

hidden networks and hosts.

Supported standards

The Brocade vRouter implementation of IPv6 complies with the following standards:

•

RFC 2460: Internet Protocol, version 6 (IPv6) Specification

RFC 4443: Internet Control Message Protocol (ICMPv6) for the Internet protocol version 6 (IPv6)

Brocade Vyatta Network OS IPv6 Support Configuration Guide, 5.2R1

53-1004723-0111

IPv6 addressing

IP addresses generally take the following form:

x:x:x:x:x:x:x:x

where x is a 16-bit hexadecimal number; for example:

2001:0DB8:0000:0000:51DA:27C0:E4C2:0124

Addresses are case-insensitive; for example, the following is equivalent to the example given above:

2001:0db8:0000:0000:51da:27c0:E4c2:0124

Leading zeros are optional; for example, the following is a valid IPv6 address:

2001:DB8:0:0:51DA:27C0:E4C2:124

IPv6 addresses often contain many bytes with a value of zero. Successive fields of zeros can be represented by replacing them with a

double colon, as in the following:

2001:DB8::51DA:27C0:E4C2:124

Similarly the following:

2001:DB8::124

is equivalent to the following:

2001:DB8:0:0:0:0:0:0124

and this:

0:0:0:0:0:0:0:1

is equivalent to this:

::1

The replacement by the double colon may be made only once within an address, as using the double colon more than once can result in

ambiguity. For example, the following:

2001:DB8::27C0::0124

is ambiguous between these three addresses:

2001:0DB8:0000:27C0:0000:0000:0000:0124

2001:0DB8:0000:0000:27C0:0000:0000:0124

2001:0DB8:0000:0000:0000:27C0:0000:0124

IPv6 addresses that are extensions of IPv4 addresses can be written in a mixed notation, where the rightmost four bytes of the IPv6

address are replaced with the four decimal octets of the IPv4 address. In mixed notation, the four hexadecimal bytes are separated by

colons and the four decimal octets are separated by dots, as in the following example:

2001:db8:0:1::192.168.100.51

which is equivalent to

2001:db8:0:1::c0a8:6433

IPv6 forwarding

Special addresses

Like IPv4, IPv6 has some special addresses, which are used by convention for special functions. For unicast addresses, these include

the following:

•The unspecified address. This address is used as a placeholder when no address is available (for example, in an initial DHCP

address), or to stand for “any” address. In IPv6, the unspecified address can be represented as either of the following:

0:0:0:0:0:0:0:0

•The localhost (loopback) interface. The loopback interface is a software interface that represents the local device itself. In IPv4,

the address 127.0.0.1 is used by convention for the loopback interface. In IPv6, the loopback interface can be represented by

either of the following:

0:0:0:0:0:0:0:1

::1

The IPv6 address architecture is quite rich, and includes types of addressing unavailable in IPv4, such as unicast and multicast scoped

addresses, aggregatable global addresses, and anycast addresses. Multicast broadcast addresses do not exist in IPv6. For more

information about the IPv6 address architecture, consult RFC 4291, IP Version 6 Addressing Architecture.

IPv6 autoconfiguration

IPv6 supports two mechanisms for automatically configuring devices with IP addresses: stateful and stateless. Both are supported in the

Brocade 5600 vRouter.

In stateful configuration, addressing and service information is distributed by a protocol (DHCPv6) in the same way that the Dynamic

Host Configuration Protocol (DHCP) distributes information for IPv4. This information is “stateful” in that both the DHCP server and the

DHCP client must maintain the addressing and service information.

Stateless configuration uses the Stateless Address Autoconfiguration (SLAAC) protocol, which is a component of the larger Neighbor

Discovery (ND) protocol. SLAAC has a host component and a router component.

In the host component of SLAAC, the IPv6 system constructs its own unicast global address from the system’s network prefix together

with its Ethernet media access control (MAC) address. The device proposes this address to the network, without requiring approval from a

server such as a DHCP server. The combination of network prefix and MAC address is assumed to be unique. Stateless

autoconfiguration is performed by default by most IPv6 systems, including the Brocade vRouter.

In the router component of SLAAC, routers respond to Router Solicitation (RS) packets from hosts with network prefix information in the

form of Router Advertisement (RA) packet. Hosts receive these advertisements and use them to form globally unique IPv6 addresses.

The RS and RA packets also provide the router discovery function, allowing hosts to locate routers that are configured to serve as default

routers. The Brocade vRouter fully supports router-side SLAAC and router discovery, including all required configurable parameters.

The ND protocol and the router discovery function are specified in RFC 4861. IPv6 Stateless Address Autoconfiguration is described in

RFC 4862.

IPv6 forwarding

On the Brocade vRouter, IPv6 forwarding is enabled by default. If you want to disable IPv6 forwarding, use the following command in

configuration mode: set system ipv6 disable-forwarding. This command is described in Brocade Vyatta Network OS Basic System

Configuration Guide.

Brocade Vyatta Network OS IPv6 Support Configuration Guide, 5.2R1

53-1004723-0113

IPv6 neighbor discovery

IPv6 Neighbor Discovery (ND) provides a layer 3 to layer 2 address resolution mechanism for IPv6 similar to the way that Address

Resolution Protocol (ARP) provides for layer 3 to layer 2 address resolution for IPv4.

ND resolution is carried out in both the data plane and the control plane; however, it is primarily carried out in the data plane. Note that

ND caches in the control plane and data plane are no longer synchronized because entries in the two caches are managed

independently. The data plane cache contains entries for both forwarded and locally terminated traffic. The control plane maintains cache

entries only for destinations with which the local stack of the control plane communicates.

The advantages of implementing the ND protocol in the data plane are as follows:

•

Avoids bandwidth issues in deployments with distributed data planes, because ND resolution can be performed locally rather

than on a centralized controller.

Improves performance because ND does not need to send all ND packets to the control plane.

Protects against scanning DOS attacks due to resolution throttling.
