Default
: Preemptive mode is set by default
Usage Guide
: If a router (or L3 Ethernet switch) requiring high priority needs to
preemptively become the active router (or L3 Ethernet switch), the preemptive mode
should be enabled.
Example
: Setting non-preemptive VRRP mode
Switch(Config-Router-Vrrp)# preempt-mode false
21.3.8 priority
Commands: priority <value>
no priority
Function
:Configures VRRP priority; the
"no priority"
restores the default value 100.
Priority is always 255 for IP Owner.
Parameters:
< value>
is the priority value, ranging from 1 to 255.
Default
: The priority of all
backup
routers (or L3 Ethernet switch) in a Standby cluster is
100; the Master router (or L3 Ethernet switch) in all Standby cluster is always 255.
Command mode
: VRRP protocol configuration mode
Usage Guide
: Priority determines the ranking of a router (or L3 Ethernet switch) in a
Standby cluster, the higher priority the more likely to become the Master. When a router
(or L3 Ethernet switch) is configured as Master dummy IP address, its priority is always
255 and does not allow modification. When 2 or more routers (or L3 Ethernet switch) with
the same priority value present in a Standby cluster, the router (or L3 Ethernet switch)
with the greatest VLAN interface IP address becomes the Master.
Example
: Setting VRRP priority to 150.
Switch(Config-Router-Vrrp)# priority 150
21.3.9 router vrrp
Commands:router vrrp <vrid>
no router vrrp <vrid>
Function
: Creates/Removes the Virtual Router
Parameters:
< vrid >
is the Virtual Router number ranging from 1 to 255.
Default
: Not configured by default.
Command mode
: Global Mode
Usage Guide
:This command is used to create/remove Virtual Router, which is identified
by a unique Virtual Router number. Virtual Router configurations are only available when
a Virtual Router is created.
