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. If
IP Default appears in the Destination field, the entry
specifies the route the 5399 RAC 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 5399 RAC 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.
