Single HUB with dual ISPs DMVPN

[S.ashok S]

Hi,

I wish to implement DMVPN usning single hub, single router with dual ISPs and have 10 remote spoke locations connected single ISP.

Want to create two tunnel interfaces from each spoke, one is primary (ISP-1 at HUB) and another (ISP-2 at HUB)is backup.

Kindly help if anybody implemented the same setup.

Thanks in advance.

Thanks and regards,

Ashok

Hi,

DMVPN Phases

Phase 1 (obsolete)
No spoke-to-spoke tunnels
Summarization/default routing at hub is allowed
Next-hop on spokes it´s always changed by hub

Phase 2 (obsolete)
mGRE on hub and spokes
-NHRP required for spoke registration to hub
-NHRP required for spoke-to-spoke resolution
-Summarization/default routing at hub is NOT allowed
-Next-hop on spokes is always preserved by the hub

Phase 3
-NHRP required for spoke registration to hub
-NHRP required for spoke-to-spoke resolution
