grep (or map) in a void context is generally considered bad. Better to store the array in a hash, especially if you access it more than once:
my %file; @routers{@ARRAY} = undef; @interfaces{@anotherarray} = undef if (exists $routers{$zero_arg} and not exists $interfaces{$sec_arg)) { #Do stuff }

    Re-reading your problem (and if I understand it correctly), I'd do it this way:
    my %file; @routers{@ARRAY} = undef; die "Bad zero_arg" unless exists $routers{$zero_arg}; my %interfaces; @interfaces{@anotherarray} = undef; unless (exists $interfaces{$sec_arg)) { #Do stuff } # OR this, if appropriate return if exists $interfaces{$sec_arg}; #Do stuff
