Hello,
I was just wondering if any improvment has been done to DMVPN in Server Load Balancing configuration (DMVPN HUBs are behind an IOS SLB and all the spokes pointing to the single virtual IP). Apparently this is the most scalable solution going beyond 1000 spokes. The only problem with it is it did not support the spoke-spoke DMVPN. Mike Sullenberger's presentation at the mini Networkers in Toronto in 2007 stated that this missing piece is in development by Cisco.
Thanks
