Vrrp Commands; Configuring Fragmentation - Avaya G350 Administration

•
If the Main router fails, the redundant router that does not receive a response from four
consecutive polling requests (default) takes over and starts to advertise the same Virtual MAC for
ARP requests. Therefore the stations will not sense any change either in the configured default
gateway or at the MAC level.
•
VRRP has no provisions for routing database synchronization among the redundant routers. You
need to perform this manually if needed.
