multiple line VPN bonding

If we have two VyOS endpoints, is there a way to get a solution similar to SpeerFusion?
…like Bandwidth Bonding Technology SpeedFusion - Peplink

Very interesting function. do you fund vyatta howto ?

You can setup two ipsec S2S tunnels using VTI, and use OSPF equal cost load balancing.
Another option is wan-load-balancing in VyOS (for default route LB).

I have a patch from An Nguyen that allows that. See 510 Software Group (vyatta-cfg-system.git.patch).

I hope to get that into a future Vyos release.

Interesting! Great!
I hope so too.
