Database Devices in a Multiple VLAN Environment
As of this printing, the ProCurve switches that do not have a multiple
forwarding database include:
■ 1600M, 2400M, 2424M, ■ Some older AdvanceStack
4000M, and 8000M switches switches
■ Series 2500 switches

Configuring XRRP
Configuring XRRP is performed through the switch console CLI at the global
configuration level by using the xrrp command. Use the xrrp ? command to see
a list of possible options. You define which VLANs have XRRP configured
through the xrrp instance command described on page 12-22.
You should first customize the XRRP configuration, as described below, and
then enable XRRP, as described on page 12-23. Some of the configuration
parameters cannot be changed while XRRP is operational. These are identified
in the parameter descriptions below.
Customizing the XRRP Configuration
To customize the XRRP configuration, use any of the following XRRP
command options at the CLI global configuration level:
