Centralized Backup of Distributed NAT Inter-board Hot Backup

Centralized Backup of Distributed NAT Inter-board Hot Backup

Service Overview

On the network shown in Figure 11-19, a BRAS is equipped with two VSUF-80/VSUF-160/VSUI-160-E to implement inter-board hot backup, and a CR is connected to a NAT device. When both of the two VSUF-80/VSUF-160/VSUI-160-E on the BRAS become faulty, the BRAS does not perform distributed NAT on private network traffic. Instead, the private network traffic is forwarded over routes to the CR and then redirected to the NAT device for centralized NAT. After the private IP address is translated to a public IP address, the traffic goes to the Internet.

  • Deploy centralized NAT on the CR.
