Hello,
I am wonder what the difference between the two configurations below are. It seems there are two ways to configure MLPPP. Either using a multilink interface or a virtual template. One uses an unnumbered IP and one uses a /30 for the multilink interface. I see in the QOS config guids that you use option #2 for MLPPP interleave.
Which option is best practice for normal circumstances?
