SECURE ON-DEMAND TUNNELS• Branch spoke sites establish a DMVPN tunnel with

IPsec encryption to and register with the hub site

• IP routing exchanges prefix information for each site

• BGP or EIGRP are typically used for scalability

• WAN interface address used as the tunnel address, so provider network does not need to know or route customer internal IP prefixes

• Data traffic flows over the DMVPN tunnels

• When traffic flows between spoke sites, the hub assists the spokes to establish a site-to-site tunnel

• Per-tunnel QOS is applied to prevent hub site from overrunning spoke sites

DMVPN How it Works• Spokes build a dynamic permanent GRE/IPsec tunnel to the hub, but

not to other spokes. They register as clients of the NHRP server (hub) and register their NBMA address

• Active-Active redundancy model—two or more hubs per spoke• All configured hubs are active and are routing neighbors

with spokes• Routing protocol routes are used to determine traffic forwarding• A spoke will initially send a packet to a destination (private) subnet

behind another spoke via the hub, and the hub will send it an NHRP redirect.

• The redirect triggers the spoke to send an NHRP query for the data packet destination address behind the destination spoke

• The destination spoke initiates a dynamic GRE/IPsec tunnel to the source spoke (it now knows its NBMA address) and sends the NHRP reply.

• The dynamic spoke-to-spoke tunnel is built over the same mGRE tunnel interface

• When traffic ceases then the spoke-to-spoke tunnel is removed

• PfR load balances traffic based upon link utilization levels to efficiently utilize all available WAN bandwidth

Other traffic is load balanced to maximize bandwidth Voice/Video will be
