I am looking for a way to use a virtual mac address and ip address that a number of Linux routers can share to work as load balancing... I have seen this done with Windows Load balancing,,, Their has to be a way to do with Linux,,
What I am trying to do is, I have several Linux routers that perform QOS and bandwidth shaping for a wireless network.. currently up to now they were just working as simple fail over with ucarp but as well as this works I would much rather load balance them to share the load, and pick up the slack if one went down.. In order to do this I will have to make a virtual mac address and ip address to server as the gateway. The number of servers will share these mac and ip address and load balance something similar to Round Robin.

I have seen load balancing to this affect with windows, is there any implementation for Linux? I am currently running Gentoo and Slackware.

check out linux-ha.org for active / active and active / passive failover solutions.

I see lots of documentation for end servers, but using heartbeat and VLS, will this work with routers?

well heartbeat will just provide functionality to migrate an ip address from box a to box b and such like on detected failure. it's laregly irrelevant what is being done at that ip address... LVS includes keepalived which is an implementation of VRRPv2, which is exactly the protocol most clustered routers use.
