Site Recovery with site A and site B network isolated

[Neetu Bhushan]

Hi All,

I'm planning site recovery with my protected server.  It mention that i need to have my site A and site B server network to be isolated to each other so that it will not create error on my site A network (because it's the same network and subnet).  But how do I make my site B server network available to my site A users when site A disaster happened.  Do I have to modify the routing when it happened.  How do i make it automatic?  What's the best routing for it (ospf or eigrp or others)?

Thanks for any comment you may add.

Hi Rob,

You can change one of the site's ip address segment and than run OSPF between your 2 sites. It will be all dynamic. If your 2 sites are small, you can put all your routers in the same OSPF area (area 0).
