Dest
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
The index value which 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.The special interface index zero (0) means, discard the packet.
Metric1
The metric of the route as specified by the RIP protocol. When selecting routes, the route with the lowest value of ipRouteMetric1 is chosen.
Metric2
Defined, but not used by the BRICK.
Metric3
Defined, but nor used by the BRICK.
Metric4
Defined, but not used by the BRICK.
NextHop
The IP address of the next hop of this route. (In the case of a route bound to an interface which is realized via a broadcast media, the value of this field is the agent's IP address on that interface.)
Type
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 deleting the routing entry from the ipRouteTable object. That is, it effectively dissasociates 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 ipRouteType object. other(1) = none of the following; delete(2); invalid(2) = an invalidated route; direct(3) = route to directly connected (sub-)network; indirect(4) = route to a non-local host/network/sub-network Enumerations: other (1) invalid (2) direct (3) indirect (4)
Proto
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. other(1) = none of the following; local(2 = non-protocol information e.g., manually configured entries; netmgmt(3) = set via a network management protocol; icmp(4) = obtained via ICMP, e.g., Redirect; the remaining values are all gateway routing protocols: egp(5); ggp(6); hello(7); rip(8); is-is(9); es-is(10); ciscoIgrp(11); bbnSpfIgp(12); ospf(13); bgp(14) Enumerations: other (1) local (2) netmgmt (3) icmp (4) egp (5) ggp (6) hello (7) rip (8) is-is (9) es-is (10) ciscoIgrp (11) bbnSpfIgp (12) ospf (13) bgp (14) ospf-ext (31)
Age
The number of seconds since this route was last updated or otherwise determined to be correct. Note that no semantics of `too old' can be implied except through knowledge of the routing protocol by which the route was learned.
Mask
Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the ipRouteDest field. The BRICK is able to use arbitrary subnet-masks. If the subnet mask is not specified, it will be set automatically according to the following table: 0.0.0.0 default route 255.0.0.0 class-A 255.255.0.0 class-B 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. It should be noted that all IP routing subsystems implicitly use this mechanism. Host routes are created by setting the subnet mask to 255.255.255.255.
Metric5
Defined, but not used by the BRICK.
Info
A reference to MIB definitions specific to the particular routing protocol which is responsible for this route, as determined by the value specified in the route's ipRoute-Proto value. This value is currently not used by the BRICK and is therefore always set to 0.0.
