Re: dmvpn-phase-1-dual-hub-with-3000-spokes-with-ospf

topology
- it will be 2xASR 1002 with RP2 [active and backup]
- as spokes I will have 3000 non cisco routers which support [open
nhrp] - tested and works
- each spoke will have two bgp session to active and backup router
- it will be gre over ipsec tunnels
- each spoke will receive only default from hubs
- throughput from spoke max 128kbps
- phase 1 configuration

as I understand this topology with asr 1002 can chance to work?
