IP Fields in the netstat –r Command Display
Field
Explanation
Destination
The IP address of the route’s destination, followed by a slash
(/), followed by the number of 1 bits, counting from left to
right, in the Destination’s subnet mask. For example, the /24
following the IP address 132.254.1.0 indicates a subnet
mask of 24 bits (eight octets), or 255.255.255.0. (For more
information, see Defining Routes on page A12-50.) If IP
Default appears in the Destination field, the entry specifies
the route the Model 5390 server uses if it can find no other
route for a destination. If a name appears in the Destination
field, the entry is for a host route; name servers do not have
names for network routes. (However, the Model 5390 server
does not always know a host’s name.)
NextHop
The next router to which packets with the given Destination
are sent. If the Destination is a local interface, this field
displays an asterisk (*); interface routes have no next hop.
Flags
The following three flags:
First flag
(Status)
U
Q
D
The route is valid (up) and in use.
The route is valid but the interface is quiescent, i.e., the
interface is not up yet or was brought down by expiration of
the timer set by the net_activity port parameter.
The route is invalid (down) and has a metric of 16 (RIP
infinity). It will stay in the routing table for two more
minutes so that other routers can learn that it is invalid.
Second flag
(Source)
C
I
R
S
The route was learned via an ICMP redirect. This can occur
only when IP routing is disabled (by setting the routed
parameter to N).
The route is an interface route.
The route was learned via RIP.
The route is a static route, learned from a route defined in
the gateway section of the Model 5390 configuration file or
a route entered using the CLI superuser route command.
