Although our network is not yet large enough to run into scaling issues,
this is exactly our problem.   Our OSPF is relatively stable except for
two things, both on our dialup pools:
o Host level routes appearing from wandering static-ips
o Wandering networks from dial-on-demand networks.

We have more than one physical dialin POP, so summarization can't
take place on the netblocks that these items are allocated from.
As these users connect and disconnect this generates most of our
churn in our OSPF.

Any suggestions on solving this churn issue?
