Routing Flow This section shows you the flow of how the NXC determines where to route a packet. Click a
function box to display the related settings in the Routing Table section.
Routing Table This section shows the corresponding settings according to the function box you click in the
Routing Flow section.
The following fields are available if you click Direct Route or Main Route in the Routing Flow section.
# This field is a sequential value, and it is not associated with any entry.
Destination This is the destination IP address of a route.
Gateway This is the IP address of the next-hop gateway or the interface through which the traffic is routed.
Interface This is the name of an interface associated with the route.
Metric This is the route’s priority among the displayed routes.
Flags This indicates additional information for the route. The possible flags are:
• A - this route is currently activated.
• S - this is a static route.
• C - this is a direct connected route.
• O - this is a dynamic route learned through OSPF.
• R - this is a dynamic route learned through RIP.
• G - the route is to a gateway (router) in the same network.
• ! - this is a route which forces a route lookup to fail.
• B - this is a route which discards packets.
• L - this is a recursive route.
Persist This is the remaining time of a dynamically learned route. The NXC removes the route after this
time period is counted down to zero.
The following fields are available if you click Policy Route in the Routing Flow section.
# This field is a sequential value, and it is not associated with any entry.
PR # This is the number of an activated policy route. If you have configured a schedule for the route,
this screen only displays the route at the scheduled time.
Incoming This is the interface on which the packets are received.
