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.
