Can you show the complete configuration? At least we know that ospf is not running on the lo0 interface so thats why you are not seeing the route being advertised. BTW did you also enable family inet6 on the lo0 interfaces? If not, enable it. Are you running in pure router mode or flow mode?Do you have any firewall filters enabled? Try adding the passive option to the lo0 interface uder ospf3 area 0. SO here is a couiple of suggestions, and like I said I am just shooting from a troubleshooting standpoint. From the top of the heirarchy, save the configuration on both routers. Then delete ospf3 and configure ospf and test if the route is advertised. Next configure ospf3 without realm ipv4-unicast. Maybe there is a bug running this feature on the vm.
