Configuring VRRP
If port 3/1 on VRRP router A goes down, the master for virtual router A is still functioning but worksta-
tion clients 1 and 2 will not be able to get to the Internet. With this tracking policy enabled, however,
master router 1's priority will be temporarily decremented to 50, allowing backup router 1 to take over and
provide connectivity for those workstations. When port 3/1 on VRRP router A comes backup, master 1
will take over again.
Note. Preempt must be set on switch A virtual router 1, and switch B virtual router 2, in order for the
correct master to assume control once their respective ports 3/1 return to viability. In our example, once
port 3/1 on switch A is functioning again we want switch A to reestablish itself as the master. See
Preemption for Virtual Routers" on page 22-12
