Operation Manual – VRRP
H3C S9500 Series Routing Switches
No physical loops exist between Switch A, Switch B and Host Server, and STP is
not enabled.
Switch A is the master while Switch B is the backup. No physical link is available
between Switch A and Host Server.
Normally, Switch A acts as the gateway. The traffic sent from Host Server is forwarded
at Layer 2 through Switch B to Switch A which then forwards the traffic at Layer 3 to the
IP network.
It is required to configure Switch B to monitor the link to Switch A. If Switch A fails or the
link between Switch A and Switch B fails, Switch B becomes the master and acts as the
gateway instead of Switch A. Then, the traffic from Host Server is forwarded to the IP
network directly through Switch B. The state switching delay should be in milliseconds.
