(VRRP)
Virtual Router Redundancy Protocol (VRRP) provides fault-tolerant routing
on a LAN by eliminating the single point of failure that exists when hosts
are configured with a static default gateway. This chapter provides
guidelines and other key information about configuring VRRP on your
system.
For more information about VRRP, see the Implementation Guide for your
system.
For the CoreBuilder ® 9000 platform, the commands in this chapter apply
to Layer 3 switching modules only.
Menu Structure The commands that you can use depend on the system that you have,
your level of access, and the types of modules and other hardware
options that are configured for your system. The following diagram
shows the complete list of commands for all systems. See the checklist at
the beginning of each command description in this chapter for whether
your system supports the command.
