Carrier Grade NAT 4 – CGN 4

Upcoming Classes

Carrier Grade NAT 4 – CGN 4

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.

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.

  • Classroom Discussion     40%
  • Lab Exercises     60%
  • A10 Networks SysAdmin Course OR equivalent ACOS CLI, aVCS, and VRRP-A experience
  • Network Operations (NetOps)
  • Development Operations (DevOps)
  • Application Engineers (AppEng)
  • Network Security (NetSec)
  • Architects (Arch)
