|IWAN Transport Independant Design (TID)|
Using Dynamic Multipoint VPN (DMVPN) IWAN provides capabilities for easy multi-homing over any carrier service offering, including Multiprotocol Label Switching (MPLS), broadband, and cellular 3G/4G/LTE. More importantly, the design simplifies the routing design with a single routing control plane and minimal peering to providers, making it easy for organizations to mix and match and change providers and transport options. Two or more WAN transport providers are recommended to increase network availability up to 99.999%. Additionally, the Cisco DMVPN solution provides an industry-proven and U.S. government FIPS 140-2 certified IPsec solution for data privacy and integrity protection, and automatic site-to-site IP Security (IPsec) tunnels.
