How to find the VIP of a cluster

Hello -

I have a setup with three Windows 2003 clusters - Clus 1, Clus 2 and Clus 3.
Each cluster has an EFL cluster name (and EFL cluster IP address) AND an EBL
cluster name (and EBL cluster IP address). That makes a total of 6 "clusters"
3 EFL and 3 EBL clusters. All these six "clusters" are mapped to a single
virtual IP or a "Big IP". Any traffic which hits this "Big IP" will be
directed to one of the above three clusters. I'm trying to find out the
command that gives me the VIP or the Big IP address. I tried with a few
combinations of the "wlbs" flavor but can't seem to get it right.

Any help with this is greatly appreciated.
