IPv6 Configuration
ThecommandsinthischapterperformconfigurationofIPv6parametersontheEnterasysG‐
Series.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 17,IPv6Mana gement.
Overview
IPv6andIPv4coexistontheEnterasysG‐Series.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G‐Series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Un icast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G‐Series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autoconfigurationis
part
ofRouterAdvertisementandtheG‐Seriescansupportbothstatelessandstateful
* 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 “Activating Licensed Features”
on page 2-27 in order to enable the IPv6 routing configuration command set. If you wish to purchase an IPv6
routing license, contact Enterasys Networks Sales.
