DMVPN Dual Hub - OSPF - Migrate to Stub Network

[trippi]

I have a DMVPN Dual Hub network running OSPF.

I would like to migrate to a stub network.

We have approximately 40 spokes.

Anyone have an idea on how to do a graceful migration?

Thanks!

Hi,

As soon as you change from normal ospf area to stub, you peering will go down.  So there is going to be some down time until you change the opposite site to stub too.  Make sure to do it during on outage window.
