Command Usage
• VRRP advertisements from the current master virtual router include
information about its priority and current state as the master.
• VRRP advertisements are sent to the multicast address 224.0.0.8. Using a
multicast address reduces the amount of traffic that has to processed by
network devices that are not part of the designated VRRP group.
• If the master router stops sending advertisements, backup routers will bid to
become the master router based on priority. The dead interval before
attempting to take over as the master is three times the hello interval plus half
a second
Example

• group - Identifies the VRRP group. (Range: 1-255)
