No problems, happy to help. It literally took me days to get it to work. Where ever I looked, the configurations they suggested were different - although cisco are great, it can be a pain that you can do the same thing in so many different ways and get different results. The other thing you need to do is add some lines to your radius server, here is what I use; I cant remember why I needed the last one but it took me ages to find that option and it fixed up one of my issues with the MLPPP staying up. preauth:ppp-multilink=1 multilink:max-links=3 multilink:min-links=2 multilink:load-threshold=0 -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Paul Julian Sent: Friday, 1 August 2014 9:49 AM To: 'MikroTik Australia Public List' Subject: Re: [MT-AU Public] PPP Multilink on Telstra ADSL2 Thanks Paul, I really appreciate you sharing that information, you have a couple of additional lines in your template which I don't have, perhaps that's an issue, I don't have the last two so might add those into the config and give it a try !

It's pretty standard config, just make sure you have 'ppp multilink' on your virtual template and you must use "multilink bundle-name auth".

Did you find there were any tricks needed for the bundling setup on the LNS or was it standard stuff ? We are running a Cisco 7301 as our LNS and we have the multilink bundle-name defined. I admit that I have only been able to try it on one dslam but do have an opportunity to try again hence the question initially.

There are sometimes issues with Telstra dslam's locking ports and there are also sometimes pauses in data transfer. Different locations work at differing degrees of success, which probably comes down to whether your connections are both on the same dslam and the also the type of dslam (Telstra for example have various dslams throughout their network). Multiple logins of the same username, is also a requirement due to MikroTik implementation. Not a problem for us as we also run the back end LNS network ;) -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Paul Julian Sent: Thursday, 31 July 2014 8:10 PM To: public@talk.mikrotik.com.au Subject: [MT-AU Public] PPP Multilink on Telstra ADSL2 Just wondering if anybody has successfully implemented the Mikrotik PPP Multilink setup through Telstra DSLAM's before ? We can't seem to get it to work, nothing we do seems to make the second link come up, I'm not sure if it's a Telstra thing or a Mikrotik thing Anybody had any luck with it ?
