I am configuring two such p-p routers in the Internet core for one interface on each router. When an IPv6 address is configured/acquired by the interface, the interface acts as a host. Once each of the addresses have been manually configured on the interface, the interface can also be configured for IPv6 ND to send an RA with no PIO. From a received RA, each interface learns the default router. Then I configure routing on each of the interfaces. All these operations ran orthogonal. RA with no PIO also signals to the receiving interface to send packets to the default router. The only reason each router interface on this p-p network is signaled to send data to default router (ND off-link model) is because then the router interface does not initiate anycast data forwarding because a /127 was configured on each interface.
