It depends solely on the operating system and whether IPv6 privacy is in effect. Normally, the client will perform stateless automatic address configuration (SLAAC). It goes pretty much like this: The router announces the 64 bit prefix, usually every 200 seconds, but the client may request a new announcement at any time. The client generates a 64 bit interface identifier based on its 48 bit MAC address. The client then concatenates the supplied prefix with the generated interface identifier. The client then performs duplicate address detection (DAD), and if everythings checks out, the client got its IPv6 address. Given this prefix fd8f:d6d0:e6e7:100::/64, and this MAC address 50:e5:49:41:4d:70. The client would then generated this interface id: 52e5:49ff:fe41:4d70. The Universal/Local bit of the MAC address is inverted, and FF:FE is placed at center. (It really ought to be FF:FF, but way back in time someone misread the IEEE standards regarding conversion from 48 bit MAC addresses to EUI64 format. This oversight doesn't really matter.) The same client would then aqcuire this IPv6 address: fd8f:d6d0:e6e7:100:52e5:49ff:fe41:4d70, and perform DAD. The client gets its IPv6 default route/gateway from the router announcement. Of course, you may configure the IPv6 address and gateway manually on the client, say fd8f:d6d0:e6e7:100::1337/64 (client's address) and fd8f:d6d0:e6e7:100::101 (gateway's address). > On Wed, May 22, 2013 at 6:54 PM, Trond Endrestøl < > Trond.Endrestol@fagskolen.gjovik.no> wrote: > > > On Wed, 22 May 2013 18:21+0530, hrkesh sahu wrote: > > > > > Hi Trond , > > > Thanks a lot. > > > Now i am able to ping to other network with IPv4 address. > > > > > > For IPv6 I added these lines in rc.conf - > > > first I included - > > > ipv6_gateway_enable="YES" > > > > > > ++> Laptop1( Ipv6 address fe80::224:7eff:fee0:6b51) is connected to > > > interface rl0 ( ipv6 address - fe80::21f:b5ff:fe48:9f73) > > > While doing ping6 from "fe80::224:7eff:fee0:6b51" to > > > "fe80::21f:b5ff:fe48:9f73" - it is working.
