my %interfaces =  (
    R1R0  => 1,
    R1R6  => 2,
    R2R0  => 3,
    R2R6  => 1,
    R3R61 => 2,
    R3R62 => 3,

push (@routers, $r[1],$r[2],$r[3]);

foreach my $rh (@routers) {
        
  $rh->config(" deactivate  $interfaces{$R1R0}");
}

In the above code, there are 6 interfaces, 2 from each router, (R1, R2, R3). I want to deactivate each interface as defined in hash from all the routers. For that, am doing a foreach (to get the router handles separately), and execute the action. The problem with this is, when foreach executes the first router, say $r[0], only the first interface (defined in hash/key as R1R0) is executed. I want to execute both (first and second hash/key pair for R1), when foreach is executed for $r[0], similarly for R2 and R3. I found the only way is defined a seperate hash for all the three routers as below 

%interfaces_R1 = (
R1R0 =>
R1R6 =>
);

%interfaces_R2 =(

Is there a better way to do it
