Currently, you have to use peer addresses for unnumbered
interfaces in OSPF:
On one router:
ip addr add 10.90.255.3 peer 10.90.255.4 dev eth0
On the other:
ip addr add 10.90.255.4 peer 10.90.255.3 dev eth0
Although generally you could use the same pair on both interfaces,
i don't know if i tested such case and if there are no hidden
problems related to this.
Also note that addresses of unnumbered interfaces are not propagated
by default, So you would also need some regular or loopback/stub
interface added to OSPF:
ip addr add 10.90.255.3/32 dev lo
