Another option is to push the constants into AVP arrays at startup (I 
assume there is some sort of init route at this point, otherwise a 
module init event-route):

    $(avp(s:routers)[0]) = "10.10.10.1";
    $(avp(s:routers)[1]) = "10.10.10.2";
    $(avp(s:routers)[2]) = "10.10.10.3";

You can then iterate through them, using is_avp_set() to check if 
something exists at the current index/array subscript:

    $var(i) = 0;

    while(is_avp_set("$(avp(s:routers)[$var(i)])")) {
       xlog("L_INFO", "Router is: $(avp(s:routers)[$var(i)])\n";
       $var(i) = $var(i) + 1;
    }
