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.

IP Routing Destination window

The IP Routing Destination window (see figure 86) shows next-hop routing information. Clicking on a Desti- nation in the IP Routing Information window displays this window.

Figure 86. Routing Destination window

Route Destination (ipRouteDest)

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.

Mask (ipRouteMask)

Indicates the mask to be logical-ANDed with the destination address before being compared to the value in the ipRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the ipRouteMask by determining whether the value of the corresponding ipRouteDest field belongs to a Class A, B, or C network, and then using the appropriate mask from Table 3 on page 200.

Interface (ipRouteIfIndex)

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.

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.
