Model 3120 RAS Administrators’ Reference Guide 16 • IP
• 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.
Note
Setting this object to the value invalid(2) has the effect of invalidating
the corresponding entry in the ipRouteTable object. That is, it effec-
tively disassociates the destination identified with said entry from the
route identified with said entry. It is an implementation-specific mat-
ter 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 cur-
rently in use. Proper interpretation of such entries requires examina-
tion 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 access server to support an interface. For example, adding a route for a new dial-in
user.
• 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.
• radius(6)—Provided in RADIUS response 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.
