High Availability Configurations

BLADEOS 6.5.2 Application Guide

Figure 43 shows an example configuration where two G8124s are used as VRRP routers in an active-active configuration. In this configuration, both switches respond to packets.

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 active-active configuration across all the VRRP-capable switches in a LAN.

Each VRRP-capable switch in an active-active configuration is autonomous. Switches in a virtual router need not be identically configured.

In the scenario illustrated in Figure 43, traffic destined for IPv4 address 10.0.1.1 is forwarded through the Layer 2 switch at the top of the drawing, and ingresses G8124 1 on port 1. Return traffic uses default gateway 1 (192.168.1.1).

If the link between G8124 1 and the Layer 2 switch fails, G8124 2 becomes the Master because it has a higher priority. Traffic is forwarded to G8124 2, which forwards it to G8124 1 through port 4. 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 active-active example, perform the following switch configuration.
