Hi All. I'm trying to get my head around IPv6 addressing using general prefixes. I am trying to set up addressing using my ISP allocated global unicast prefix. It is in the form of:
2001:44b8:4121:xx00::/56
From this I want to break it up into subnets as follows:
2001:44b8:4121:xx01::/64
2001:44b8:4121:xx02::/64
2001:44b8:4121:xx03::/64
...
I've set up a general prefix:
ipv6 general-prefix inode_gp 2001:44B8:4121:xx00::/56
The issue I'm having is how to apply this to the various interfaces using eui-64 and have each interface (or sub-interface) sitting on its respective subnet. I cannot seem to find the correct command syntax to do this. I have been using the format:
interface Loopback0
ip address 1.1.4.2 255.255.255.255
ipv6 address inode_gp ::/64 eui-64
ipv6 enable
Which gives me:
2001:44B8:4121:xx00:223:EBFF:FEAD:EE60
The command takes but there is no subnet. How do I get it to use he general prefix, use eui-64 to generate the node address and stick a subnet in between?
There is plenty of stuff out there on general prefixes but nothing I can find that shows how to subnet and use eui-64 together. Not that it makes any difference but this config is on an Aironet AP1142. I want to use a similar config on my C887VAM.
Matt.
