Routing Protocols Over Async Back-To-Back?

I have set up two 2600 routers in a back-to-back configuration using the AUX
ports.  (One of my serial cards was bad, so I've had to get creative in
order to build a lab.)

Connectivity is fine.  But I cannot seem to get RIP or OSPF to pass
information between the two routers.  Is this possible?

Here is the interface and routing config from one of the routers:

interface Async65
 ip address 172.30.1.2 255.255.255.0
 encapsulation ppp
 async dynamic routing
 async mode dedicated
!
router ospf 1
 log-adjacency-changes
 network 10.10.100.0 0.0.0.255 area 0
 network 172.30.1.0 0.0.0.255 area 0

Here is a show ip ospf database:

Router-2#sh ip ospf database

            OSPF Router with ID (172.30.1.2) (Process ID 1)

                Router Link States (Area 0)

Link ID         ADV Router      Age         Seq#       Checksum Link count
172.30.1.2      172.30.1.2      1582        0x80000002 0x00013A 2

sh ip ospf neighbor has nothing in it.


Thanks.
