Single NIC Multicast NLB Cluster and RRAS's RIP

Recently, I was playing around with a single NIC multicast NLB cluster. So
far, the cluster has only 2 hosts. It was intended to service VPN access. The
cluster is behind NAT and use different off-subnet IP address ranges for each
host in the cluster, so the NAT device needs to be aware of the routing for
the off-subnet ranges. The problem I am experiencing is that only one of the
two hosts can bhave the NAT device as RIP neighbors. If I remove one of the
host from the NLB cluster, then both machines will have the NAT device as RIP
neighbors.

Is it caused by the current setup I have? Is there anyway to work around it?


Thanks.

I don't understand the point of un-joining the NLB cluster and leaving it
like that after you purposefully joined it in the first place.

Removing one of the host is just what I did to discover that it's the NLB
cluster setup interfering with RIP. I had no intention of breaking the
cluster. In fact, I have already add the host back. What I really wish to
know if it's a known situation (RIP and NLB), or could it have been something
I did wrong while setting things up.
