If you really just want to extract each MAC address from the hashref, this should do it:
use strict;
use warnings;
my $result =
{
'10.4.20.21' => { #IP Address from CPE equipment.
'1' => '0x0a003edd8706', #Bridge table entry #1
'2' => '0x1a003edd8706', #Bridge table entry #2
'3' => '0xc03f0eddfb3b' #Bridge table entry #3
}
};
for my $mac (values %{(values %$result)[0]}) {
print "Mac addr: $mac\n";
}
Depending on your use case you may need more than this but hopefully it points you in the right direction.
