Command History
Usage Guidelines VRRP advertisements communicate the priority and state of the virtual router master. The
advertisements are encapsulated in IP packets and are sent to the IPv4 multicast address that is assigned
to the VRRP group.
VRRP uses a dedicated Internet Assigned Numbers Authority (IANA) standard multicast address
(224.0.0.18) for VRRP advertisements. This addressing scheme minimizes the number of routers that
must service the multicasts and allows test equipment to accurately identify VRRP packets on a segment.
The IANA-assigned VRRP IP protocol number is 112.
This command does not require a license.
Examples This example shows how to specify an advertisement interval of 200 seconds for VRRP group 250:
switch# configure terminal
switch(config)# interface ethernet 2/1
switch(config-if)# no switchport
switch(config-if)# vrrp 250
switch(config-if-vrrp)# advertisement-interval 200
switch(config-if-vrrp)#
Related Commands
