Is it possible to use more than one hub with a DMVPN WAN design for the purposes of resilience? Failing that, can two IP addresses for the hub be specified on each spoke?
This is only a small network comprised of about 10 spokes with ADSL and a hub with SDSL. The hub is going to be an 1841. Are we likely to run into resource [CPU, RAM] problems on the hub with that number of spokes? If not, how many spokes is an 1841 good for?
