Table 7-10 Configuration: Network Configuration: Ip Routing Table - ZyXEL Communications NetAtlas IES-1000 User Manual

The following table describes the labels in this screen.

Table 7-10 Configuration: Network Configuration: IP Routing Table

LABEL
Dest This is the destination IP address of this route. An entry with a value of 0.0.0.0 is considered a
default route. Multiple routes to a single destination can appear in the table, but access to such
multiple entries is dependent on the table-access mechanisms defined by the network management
protocol in use.
IfIndex This is the index value that uniquely identifies the local interface through which the next hop of this
route should be reached. The interface identified by a particular value of this index is the same
interface as identified by the same value of ifIndex.
Metric1 This is the primary routing metric for this route. The semantics of this metric are determined by the
routing protocol specified in the route's Proto value. If this metric is not used, its value should be set
to -1.
Metric2 This is an alternate routing metric for this route. The semantics of this metric are determined by the
routing protocol specified in the route's Proto value. If this metric is not used, its value should be set
to -1.
Metric3 This is an alternate routing metric for this route. The semantics of this metric are determined by the
routing protocol specified in the route's Proto value. If this metric is not used, its value should be set
to -1.
Metric4 This is an alternate routing metric for this route. The semantics of this metric are determined by the
routing protocol specified in the route's Proto value. If this metric is not used, its value should be set
to -1.
NextHop This is the IP address of the next hop of this route. In the case of a route bound to an interface that
is realized via a broadcast media, the value of this field is the agent's IP address on that interface.
Type This is the type of route. Note that the values direct (3) and indirect (4) refer to the notion of direct
and indirect routing in the IP architecture. Setting this object to the value invalid (2) has the effect of
invalidating the corresponding entry in the Table object. That is, it effectively disassociates the
destination identified with said entry from the route identified with said entry.
It is an implementation-specific matter as to whether the agent removes an invalidated entry from
the table. Accordingly, management stations must be prepared to receive tabular information from
agents that corresponds to entries not currently in use. Proper interpretation of such entries requires
examination of the relevant Type object.
Proto This is the routing mechanism via which this route was learned. Inclusion of values for gateway
routing protocols is not intended to imply that hosts should support those protocols.
Age This is the number of seconds since this route was last updated or refreshed.
Mask This is the mask to be logical-ANDed with the destination address before being compared to the
value in the Dest field.
For those systems that do not support arbitrary subnet masks, an agent constructs the value of the
Mask by determining whether the value of the correspondent Dest field belongs to a class A, B, or C
network, and then using one of:
Mask Network 255.0.0.0
Mask Network 255.255.0.0
Mask Network 255.255.255.0 Class C
If the value of the ipRouteDest is 0.0.0.0 (a default route), then the mask value is also 0.0.0.0.
