In order to configure something like this i first need to understand something - i have read a lot about IPv6 but i didn't understand something:
This is the stature of an IPv6 address, and the confusing part to me is the 0012 - the subnet.
2001:0db8:3c4d:0012:0000:0000:1234:56ab
Global prefix Subnet interface ID
I need to define IPv6 on multiple devices so i need to make sure that i address them correctly, and I obviously don't understand it correctly as I think of it as SM but there is an option to add an actual SM using the regular /70 and so on, and there are values in this field that don't coincide with being a SM – like0 or ffff or ffe0 and so on, so please explain this to me.
Next:
* i defined IPv6 address on an XP Client with the IP of 2001:10:10::85. There is no option to define prefix length so i don't know which Subnet Mask it's using. According to this address there is no subnet field set so i don't know what SM it thinks it is (i was instructed to define it like this).
* I have an F5 that was defined with the IP 2001:10:10::199 and with a subnet of ffff:ffff:ffff:ffff:0:0:0:0:0 which i have no idea what it means - what is this SM?
* And now i have to setup a Catalyst 4500 to act as the Gateway for this network but i don't know which Subnet Mask to set for its address - 2001:10:10::81
Also, after we can figure it out, i will appreciate some info on what has to be defined on the switch - i know that ipv6 enable has to be defined on the interface vlan that i set to use ipv6 and ipv6 unicast-routing has to be activated on the global.
But is there anything else - we configure the IPs of the client manually and set the DNS manually - so are there other things that have to be setup?
Thanks
