well no. You might be the first. (I haven't looked at the other poster's reply.

As far as the GLB is concerned, the RLB is a realserver listening on the GVIP. You need two things on the RLB o a set of ipvsadm rules accepting packets to the GVIP and sending them by LVS-NAT to 192.168.1.x o something on the RLB that will accept a packet to the GVIP. This is going to require a little trickery, but nothing too fiendish. The state of the art as it was a couple of years ago is here http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.routing_to_VIP-less_director.html >From memory, probably the simplest is to put the GVIP on a (any) device (lo, dummy, some ethX) on the RLB. Since the location of the RLB will not be receiving advertisements for the GVIP (they'll only be sent to the location of the GLB), then you won't have to handle the ARP problem at the RLB. > I can solve the issue by tunnelling the GVIP:port > combination to the RVIP:port within the Regional box > itself, but this seems a bit of a messy solution? I'm not sure what you want to do here, but it sounds like you'll be bypassing the load balancing of the GLB.
