IPv6 Routing Configuration
25-4 Configuring and Managing IPv6
Neighbor Discovery is the IPv6 replacement for ARP. The Enterasys Fixed Switches support
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
autoconfiguration is part of Router Advertisement and the Enterasys Fixed Switches can support
both stateless and stateful autoconfiguration of end nodes. The Enterasys Fixed Switches support
both EUI-64 interface identifiers and manually configured interface IDs.
Refer to the following RFCs for more information about Neighbor Discovery and stateless address
autoconfiguration:
• RFC 4861, “Neighbor Discovery for IP Version 6”
• RFC 4862, “IPv6 Stateless Address Autoconfiguration”
For ICMPv6, error PDU generation is supported, as are path MTU, echo, and redirect.
Router Advertisement is an integral part of IPv6 and is supported. Numerous options are
available including stateless/stateful address configuration, router and address lifetimes, and
Neighbor Discovery timer control. Ping and traceroute applications for IPv6 are provided.
