I have been doing some proof of concept testing with VRRP & have a question re failover conditions.
What i found was that when the topology changed with a backup link between the routers & rapid per vlan spanning tree, then the standby router went Active for around 30 seconds. However with HSRP configured on the same routers, there is no change it the active standby relationship between HSRP.
If i change the advertisement timer to another value, i.e. 3 seconds, then that is the delay before the standby router goes active.
So if i change the advertisement timer to 3, then the standby router goes active after 3 seconds, then back to standby after 30 seconds.
Is this normal operation for VRRP?
