Load balancing of l2vpn traffic over multiple ipsec vpn tunnels

One or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by one or more processors, cause the one or more processors to perform:

• performing, by a gateway, a lookup of available virtual tunnel interfaces (“VTIs”) implemented in the gateway to determine a plurality of VTIs;
• generating a hash value from contents of one or more inner headers of a packet;
• based on the hash value, determining a VTI device identifier;
• wherein the VTI device identifier uniquely identifies a particular VTI from the plurality of VTIs;
• and
• relaying the packet on a gateway output port that is associated with the particular VTI to allow forwarding of the packet via a particular IPsec VPN tunnel of a plurality of IPsec VPN tunnels.

An edge service gateway implemented in a computer network and configured to implement mechanisms for load balancing of L2VPN traffic over multiple IPsec VPN tunnels, the edge service gateway comprising:

• one or more processors;
• one or more memory units;
• and
• one or more non-transitory computer-readable storage media storing one or more computer instructions which, when executed by the one or more processors, cause the one or more processors to perform:
• performing, by a gateway, a lookup of available virtual tunnel interfaces (“VTIs”) implemented in the gateway to determine a plurality of VTIs;
• generating a hash value from contents of one or more inner headers of a packet;
• based on the hash value, determining a VTI device identifier;
• wherein the VTI device identifier uniquely identifies a particular VTI from the plurality of VTIs;
• and
• relaying the packet on a gateway output port that is associated with the particular VTI to allow forwarding of the packet via a particular IPsec VPN tunnel of a plurality of IPsec VPN tunnels.
