This section outlines the commands used to enable VSS from a pair of standalone 6509-V-E switches. We will build a cluster with the configuration shown in Figure 17-9.

Since the switches start as standalone switches, we need to start configuring them individually. Once we’ve done that, I’ll show the matching configuration for the switch on the right. First, we need to put the switch into stateful failover mode, which we do as follows:
conf tEnter configuration commands, one per line. End with CNTL/Z. 6509-VE-Left(config)#
mode ?rpr Route Processor Redundancy sso Stateful Switchover 6509-VE-Left(config-red)#
You can view the redundancy state with the

If the router will be running OSPF, you should add the following commands to the OSPF configuration. (We’re not concerned with ...
