IPv6 configuration

robbyrne22

Hi all,

I need to configure a router with IPv6. I want 3 machines connected to a router with only 2 ports, so I'll need to configure sub-interfaces. I'm a little rusty on the steps to configure the router, and I've never done it with IPv6 addresses.

Could anyone give me help with the configuration?

currently I have 2 virtual machines running on my laptop. one with an address of fe80::a00:27ff:fec0:e8a7/64 Scope:Link
the other:
fe80::a00:27ff:fef5:4910/64 Scope:Link

So out the other interface on the router I'll have a PC connected and this must be on a different subnet.

Any help would be greatly appreciated!

Rob

If you need to do static for v6 between pc router
2001:db8:1::1/64 router
2001:db8:1::2/64 pc

Or you could just use slaac were the pc detects the routers subnet and automaticly assign address based on prefix, but the router subnet needs to be /64.

Hi Noclee thanks for reply. I configured the interfaces on the router
fa0/0 1111:1111:1111:1111::/64 eui-64
fa0/1.1 2222:2222:2222:2222::/64 eui-64
fa0/1.2 3333:3333:3333:3333::/64 eui-64

The machines have addresses configured already. Would I be right saying that the last Octet of the IPv6 address denotes the subnet?

eui-64 will always have /64 mask, the pc will learn its subnet via router-advertisements from the corresponding router interfaces subnet.
