Hi LVS...
I have a PPPoE/L2TP concentrator that make Routing, NAT,
firewall,
Traffic Shapping, QOS and 802.1q for PPPoE and L2TP users connected to
it. I'm looking for a way to implement redundancy and scalability in
my solution and thought LVS would help.
Is LVS able to load balance a PPPoE server? reading howtos and
docs I've found nothing on PPPoE, VPN or VLAN examples. The Director
is
told to be a "L4 switch" what can be a problem for L2 protocols.
PPPoE is PPP over Ethernet it can be handled via ppp daemon on the
linux box. I have no idea what the packets look like. There is an
open source pppoe client/server available for Linux. L2TP tunnels
layer 2 over layer 3 (IP) so, in theory that could be load balanced,
probably with LVS-DR. 802.1q VLAN stuff could be handled by keepalived
to bring VLAN interfaces up/down and attach IPs to the interfaces. I
think if you setup an LVS-DR and use iptables rules to mark all of the
packets you might be able to make a PPPoE/L2TP load balancer. Are you
looking to build a Redback SMS type system?
