High availability configurationsThe HP 10GbE switches offer flexibility in implementing redundant configurations. This section discusses the
The following figure shows an example configuration, where two switches are used as VRRP routers in an
Figure 27
Although this example shows only two switches, there is no limit on the number of switches used in a redundant configuration. It is possible to implement an
Each
In the scenario illustrated in the figure, traffic destined for IP address 10.0.1.1 is forwarded through the Layer 2 switch at the top of the drawing, and ingresses Switch A on port 20. Return traffic uses default gateway 1 (192.168.1.1). If the link between Switch A and the Layer 2 switch fails, Switch B becomes the Master because it has a higher priority. Traffic is forwarded to Switch B. Return traffic uses default gateway 2 (192.168.2.1), and is forwarded through the Layer 2 switch at the bottom of the drawing.
To implement the
