One thing to remember is that if the topology is changing (i.e. you're
configuring things in RIP or OSPF) that cause the LSA's to change, the line
will come up to pass along the topology changes.

The ethernet interface is RIP. The bri interface is
ospf. the ethernet interface is being redistributed
into ospf. If I do a show ip ospf interface, it shows
that the interface is being run as a on-demand.
However, when the link drops, OPSF brings the link
back up.
