8 • IP
Next Hop (ipRouteNextHop)
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.)
Interface (ipRouteIfIndex)
The index value that 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.
Type (ipRouteType)
One of the following route types:
•
other(1)—none of the following
•
invalid(2)—an invalidated route
•
direct(3)—route to directly connected (sub-)network
•
indirect(4)—route to a non-local host/network/sub-network
Note
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 ipRouteTable 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 ipRouteType object.
Protocol (ipRouteProto)
The routing mechanism via which this route was learned. Inclusion of values for gateway routing protocols is
not intended to imply that hosts must support those protocols.
•
unknown(0)
•
local(1)—Added by the DACS to support an interface.
•
user(2)—Added by an administrator on the IP Routing Information table or via SNMP management tools.
•
dspf(3)—Not currently implemented.
•
rip(4)—Learned via reception of RIP packet.
•
icmp(5)—Learned via reception of ICMP packet.
Info (ipRouteInfo)
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 ipRouteProto value. If this information is not present, its value
should be set to the OBJECT IDENTIFIER { 0 0 }, which is a syntactically valid object identifier, and any
conformant implementation of ASN.1 and BER must be able to generate and recognize this value.
