OSPF: Router id sometimes is not selected correctly

[mattiaswal]

Current Behavior

When apply a whole configuration, the router id (sometimes) gets selected before all interfaces/address is created. Have not seen it on reboot only running tests.

admin@R1:/> show ospf neighbor 

Neighbor ID     Pri State           Up Time         Dead Time Address         Interface                        RXmtL RqstL DBsmL

Expected Behavior

admin@R1:/> show ospf neighbor 

Neighbor ID     Pri State           Up Time         Dead Time Address         Interface                        RXmtL RqstL DBsmL
10.0.0.4         1 Full/-          22m17s             3.866s 10.0.41.1       e5:10.0.41.2                         0     0     0
10.0.0.3         1 Full/DR         22m14s             3.479s 10.0.13.2       e6:10.0.13.1                         0     0     0
1.1.1.1          1 Full/Backup     22m10s             3.200s 10.0.12.2       e7:10.0.12.1                         0     0     0

Steps To Reproduce

Run ietf_routing/ospf_multiarea@50796912, it sets a lot of IP addresses, and use automatic router id selection on
R3, but it selects the wrong IP. Restarting ospfd changes the router id to the correct one.

CCB (core team meeting): should be more stable from a reboot since interfaces are created and set up at boot, in runlevel S, and ospfd is started in runlevel 2. Decision, target: future.
