Virtual Servers menu NAT-BasedSLB To configure the NAT-based SLB implementation both the external and internal interfaces must be configured for IP addresses. For our example they are configured as shown in Table 10-4. Table 10-4. NAT-based configuration Unit lb-1 active lb-2 standby IP address VLAN 1 Subnet mask Shared address Default route IP address VLAN 2 Subnet mask Shared address Redundancy 127 With the BIG-IPs a VIP must exist before a real server can be configured so click on the Virtual Servers menu and add the VIPs first. All you need to input is the address and port. Click on Add to make the addition. To add the rest of the real servers click on the Nodes menu. From there you can click on the Add Node button at the top to add the remainder of the nodes. You should then be all set for the NAT-style load-balancing method. Redundancy Redundancy between the two units is handled one of two ways through the network or through a serial fail-over cable. The BIG-IPs can detect if the other unit has failed or even if there isn t any network traffic on the active unit. There are several options for failure detection and fail-over between the boxes check the documentation for details. The configuration files are synced through SSH. SSH allows you to set what is known as a host key for the other unit. This allows you to log into the partner unit without a password over SSH. The SSH server checks the key sent by the client and if they match the connection is established without a password. This is how you check to see if sync is configured correctly by logging into the partner unit via SSH without a password lb-l usr sbin ssh lb-2 Last login Fri Sep 8 22 17 29 2000 from Copyright 1996-2000 F5 Networks Inc.
