# Before You Configure Static MLPPP

Before you begin configuring static MLPPP, you must configure the physical line interfaces to be aggregated by MLPPP. See the following chapters:

- Configuring Channelized T3 Interfaces in JunosE Physical Layer Configuration Guide
- Configuring T3 and E3 Interfaces in JunosE Physical Layer Configuration Guide
- Configuring Channelized OCx/STMx Interfaces in JunosE Physical Layer Configuration Guide

The procedures described in Configuring Static MLPPP assume that a physical line interface has been configured.
