Hi all, I've seen some conversations in the past regarding aggregation of multiple xDSL connections to a main office in order to benefit from much larger bandwidth at that office and to have some sort of fault tolerance. I'm wondering how this could be achieved. To add complexity, these xDSL connections have different speeds.
I'm thinking of trunking OpenVPN or PPP tun interfaces... but I doubt that trunk can correctly cope with different interface speeds. And I don't think that OpenVPN can use an L2 tunneling tun interface. I've thought of gif+ipsec but trunk wants real Ethernet devices and I don't know if gif (even as a member of a bridge) will do. Maybe with some vether magic ? An other solution might be to use multipath routing to the main site... But since the links have different speeds... equal-cost multipath routing won't do. Finally, maybe using PF route-to ? Anyway, if you have such stories or insights... I'll be glad to hear them. Cheers, cb
