Volga,

Sorry, I didn't fully understand your scenario. Even though you said it was active/active, I was assuming an active/standby scenario where only 1 IP would be active on a box at a time. I don't think this approach would work for the scenario you are describing.

Is there some reason you can't have each box listen on all 3 IPs all the time? Then from within the script you can use $Ri [1] to determine which interface received the message.

    Hello Ben,
    Do you mean for this
    
    modparam("cfgutils", "varset", "init=i:1")
    modparam("cfgutils", "varset", "gw=s:sip:11.11.11.11;transport=tcp")
    
    or this
    
    modparam("cfgutils", "shvset", "debug=i:1")
    modparam("cfgutils", "shvset", "pstngw=s:sip:10.10.10.10")
    
    in my case will be something like
    
    
    modparam("cfgutils", "shvset", "vip1=s:192.168.10.100")
    modparam("cfgutils", "shvset", "vip2=s:192.168.10.101")
    modparam("cfgutils", "shvset", "vip3=s:192.168.10.102")
    
    If vip relocated to antother node meaning on live node 1 will be two 
    vip's ( example node 3 fail then it relocate ip address to node 1)
    How I can determine which  vip ip address should be in use.
