Could someone clarify whether OSPF is supported on the CSR100V in AWS? Pg 14 of this document says nohttp://www.cisco.com/c/en/us/td/docs/routers/csr1000/software/aws/csraws.pdf Pg 9 of this Doc describes Running OSPF with DMVPN, which is what I want...

I have a 2-Hub DMVPN setup with 10 spokes.  One hub in NJ and one in Australia.  I am migrating to NJ office to a new ISP and will obviously have an IP address change.  What is involved in changing the IP of the NJ router?
