About This Network Configuration Example

 

This network configuration example provides an overview of simplified MPLS over IPsec over 1500-byte media. It also contains a sample use case showing how to provide simplified configuration for VPLS or Layer 3 VPN services with GRE through IPsec tunneling, over 1500-byte media (Internet).

This document complements the configuration guidance provided in Example: Configuring Selective Packet Services and further explains the MPLS through IPsec over 1500byte media fragmentation and reassembly use case scenario.
