IP Routing Destination window
The IP Routing Destination window (see figure 26) shows next-hop routing information.
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 67.
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 DACS 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.
