1. A computer-implemented method for using virtual tunnel interface teaming to achieve load balance and redundancy in virtual private networks (“VPNs”), the method comprising:
receiving configuration data;
based on the configuration data, configuring a first bonded virtual tunnel interface (“bonded VTI”) on a first gateway;
establishing a plurality of VPN tunnels between the first bonded VTI and a second bonded VTI configured on a second gateway;
forming, from the plurality of VPN tunnels, an Internet Protocol Security (“IPsec”) VPN tunnel between the first bonded VTI the second bonded VTI; and
enabling communications of IPsec VPN traffic between the first gateway and the second gateway via the IPsec VPN tunnel.
