IPv6 Configuration

* IPv6 Routing License Required *

IPv6 routing must be enabled with a license key. If you have purchased an IPv6 routing license key, and have enabled routing on the device, you must activate your license as described in the chapter entitled “Activating Licensed Features” in order to enable the IPv6 routing configuration command set. If you wish to purchase an IPv6 routing license, contact Enterasys Networks Sales.

The commands in this chapter perform configuration of IPv6 parameters on the SecureStack C3. For information about specific IPv6 routing protocols, such as OSFPv3, refer to the appropriate chapters. For information about managing IPv6 functionality at the switch level, refer to Chapter 21, IPv6 Management.

Overview

IPv6 and IPv4 coexist on the SecureStack C3. As with IPv4, IPv6 routing can be enabled on VLAN interfaces. Each Layer 3 routing interface can be used for IPv4, IPv6, or both.

The SecureStack C3 supports all IPv6 address formats, including global unicast addresses, link‐ local unicast, global multicast, scoped multicast (including local scoped multicast), IPv4 compatible addresses, unspecified addresses, loopback addresses, and anycast addresses.

Refer to the following RFCs for more information about IPv6 address formats:

RFC 4291, “IP Version 6 Addressing Architecture”

RFC 3587, “IPv6 Global Unicast Address Format”

RFC 4007, “IPv6 Scoped Address Architecture”

The basic IPv6 protocol specifies PDU options of two classes, both of which are supported: hop‐ by‐hop options and destination options. While new options can be defined in the future, the following are currently supported: routing (for source routing), fragment, router alert and pad. Jumbograms are not supported. In IPv6, only source nodes fragment. Path MTU discovery is therefore a requirement. Flow labels are ignored.

Neighbor Discovery is the IPv6 replacement for ARP. The SecureStack C3 supports neighbor advertise and solicit, duplicate address detection, and unreachability detection. Router Advertisement is part of the Neighbor Discovery process and is required for IPv6. Stateless
