Haven't tried that yet - see below.

This showed the cause, I think. When I brought up eth0:1, the
router-id changed to the new IP address, even though it had
previously used the IP address of eth1 as the router ID.
Specifying a router-id in ospfd.conf seems to have sorted it
Is it best practice to hard-code a router-id in ospfd.conf?
