Hi my customer has a branch location (A) with an MPLS WAN back to the primary DC. The branch A site has a direct connection to Branch B which has a lower bandwidth WAN link to the second DC.
We would like to make use of both WAN links by intelligently load balancing traffic based on application type and latency/bandwidth of the links. My question is do I require DMVPN in this scenario to enable iWAN, where both circuits are over MPLS and not over the public internet? I.e. is DMVPN a pre-requisite for iWAN?
Also, they are currently running OSPF as their routing protocol... Will iWAN run over OSPF?
All Cisco literature that I have seen shows both DMVPN and either iBGP or EIGRP as the routing protocol, being used. Just wondering if these are required or not.
Any information would be great.
thanks
Ray
