[MT-AU Public] Interception on Mikrotik

Hi guys, we were recently granted a carrier license for another business and we are using a lot of Mikrotik equipment in that business for LNS's and wireless links etc, I was just wondering what method people used on a Mikrotik to satisfy the interception capability requirements and if anybody had any comments on which options were better than others. Most people seem to intercept at the exit of their network, however in our case it's not that simple and we will probably need to provide interception points at each LNS and we have quite a few....so I am interested in what people's thoughts are on the options in this case. Regards Paul
