Network overflow problem w/ two 7206VXR and WIN 2K Servers with WLBS (NLB)

[david]

Problem 1: When I plug the routers on the Client Network, without configuring a static ARP entry, I can't ping the Microsoft Cluster from the routers, and when I traceroute from a station on the same segment, the first step is one of the router, and the second step is the cluster (the cluster, routers, and station are on the same segment). As they are on the same segment, when I traceroute from my station, my packet should go directly to the cluster, without stepping at the router.

Problem 2: When I configure the routers with a static ARP entry for the WIN 2K Cluster, and I traceroute from a station to the cluster, the packet keeps going from one router to the other, and sometimes gets to the cluster, sometimes doesn't (the cluster, routers, and station are on the same segment). This behavior causes a lot of packets traveling on the network, causing a lot of applications to time-out, including application that aren't on the cluster.

Does anyone have experienced this type of problem ?
