Flags
- indicator flags that describe some characteristics of the route. Such flags are:
U
- the route is active and operating, the interface to be used is up;
G
- the route uses an external gateway ( the network interfaces of the system supply routes
to the networks which are directly connected, all other routes use external gateways. Thus,
the networks which are directly connected don’t have the G flag, but it is activated for all
other routes).
H
– it is a route towards a single host instead of a network.
D
- the table entry has been generated dynamically, either by a routing protocol or by an
ICMP redirect message .
M
– this route was modified by a dynamic routing protocol;
R
- the route was re-activated following update by dynamic routing protocol. Routes may be
configured as passive or static even when a protocol for dynamic routing is used.
Metric
The 'distance' to the target (usually counted in hops). It is not used by recent kernels, but may
be needed by routing daemons.
Ref
Number of references to this route. (Not used in the Linux kernel, this is why you will see the
value zero)
Use
Count of lookups for the route. Depending on the use of -F and -C this will be either route
cache misses (-F) or hits (-C).
Finally,
Iface
is the name of the network interface used for this route, the interface to which
packets for this route will be sent.
For the Ethernet interfaces there is currently a first name, respectively
adm0,
for the single physical
interface, which has several routes defined to it, and then the
adm0.5,
for the VLAN with ID=5 that
has been defined.
