VRRP Tracking
A virtual router’s priority may be conditionally modified to prevent another router from taking over as
master. Tracking policies are used to conditionally modify the priority setting whenever a VLAN, slot/
port, and or IP address associated with a virtual router goes down.
A tracking policy consists of a tracking ID, the value amount used to decrease the priority value, and the
VLAN ID, slot/port number, or IP address to be monitored by the policy. The policy is then associated
with one or more virtual routers.
Interaction With Other Features
•IP routing—IP routing must be enabled for the VRRP configuration to take effect.
•Router Discovery Protocol (RDP)—If RDP is enabled on the switch, and VRRP is enabled, RDP will
advertise VLAN IP addresses of virtual routers depending on whether there are virtual routers active on
the LAN, and whether those routers are backups or masters. When there are no virtual routers active on
the VLAN (either acting as master or backup), RDP will advertise all VLAN IP addresses. However, if
virtual routers are active, RDP will advertise IP addresses for any master routers; RDP will not adver-
tise IP addresses for backup routers.
For more information about RDP, see Chapter 17, “Configuring RDP.”
