Active-Active Redundancy

In an active-active configuration, shown in Figure 42, two switches provide redundancy for each other, with both active at the same time. Each switch processes traffic on a different subnet. When a failure occurs, the remaining switch can process traffic on all subnets.

For a configuration example, see “High Availability Configurations” on page 338.

Virtual Router Group

The virtual router group ties all virtual routers on the switch together as a single entity. As members of a group, all virtual routers on the switch (and therefore the switch itself), are in either a master or standby state.

A VRRP group has the following characteristics:

￿When enabled, all virtual routers behave as one entity, and all group settings override any individual virtual router settings.

￿All individual virtual routers, once the VRRP group is enabled, assume the group’s tracking and priority.

￿When one member of a VRRP group fails, the priority of the group decreases, and the state of the entire switch changes from Master to Standby.

Each VRRP advertisement can include up to 16 addresses. All virtual routers are advertised within the same packet, conserving processing and buffering resources.
