ospfv3... whoops...

`Begin at the beginning,' the King said gravely, `and go on till you come to the end: then stop.' 

from lewis carrol...

it's a perfectly good place to start... 

it's as though the king is describing a finite state machine...

two imperatives:

ipv6 unicast-routing

and

ipv6 router ospf x
router-id x.x.x.x

the shit won't work without ipv6 unicast-routing, and ios complains that you haven't set a router id, if you haven't set a router id... you could opt to set a router id with ipv4... that seems silly...

this is a very exciting topology...
