Course

Carrier Grade NAT 4

For training/certification requests or questions, contact: training@a10networks.com

Course Description

This course provides users with the necessary skills to implement IPv6 migration and Carrier Grade NAT scenarios for A10 ACOS deployments in service provider and data center environments.

Objectives

From a three-device ACOS cluster pre-configured with a Layer 2-3 environment, students deploy these attributes:

Carrier Grade NAT (CGN/LSN) to mitigate IPv4 address exhaustion
DNS64/NAT64 for providing IPv4 resources to IPv6 clients
CGN logging to manage NAT mappings

Students also use device tools that monitor, diagnose, and restore these attributes.
