PPP Multilink (MLPPP) over VDSL CPE Configuration

We have many customers who are unable to get the full 80/20 VDSL bandwidth therefore use multiples of two VDSL or more circuits to achieve a higher download/upload speed.¬† As Exascale has its own national IP network (AS61049) and Layer 2 Tunnel Protocol (L2TP) Network Servers (LNS) we’re able to enable PPP Multilink¬† for our customers.¬† PPP Multilink enables the bundling of PPP (Point to Point Protocol) sessions.

We’ve lab tested the below configuration using both Cisco 1941, Cisco 2901 series routers using EHWIC-VA-DSL-A line cards.
