Abstract: In an embodiment, a computer-implemented method for using virtual tunnel interface teaming to achieve load balance and redundancy in virtual private networks (“VPNs”) is disclosed. In an embodiment, a method comprises: receiving, by a gateway, configuration data from a control plane; based on the configuration data, configuring on the gateway a bonded virtual tunnel interface (“bonded VTI”) having a plurality of slave virtual tunnel interfaces (“slave VTIs”); configuring a plurality of VPN tunnels between the plurality of slave VTIs configured on the gateway and a plurality of slave VTIs configured on a remote gateway; configuring an IPsec VPN tunnel between the bonded VTI configured on the gateway and a corresponding bonded VTI configured on the remote gateway; logically combining the plurality of VPN tunnels into the IPsec VPN tunnel; and enabling communications of IPsec VPN traffic via the IPsec VPN tunnel.
