ipRouteMask 1.3.6.1.2.1.4.21.1.11

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 correspondent

ipRouteDest field belong to a class-A, B, or C network, and then using one of the following:

mask network

255.0.0.0 class-A

255.255.0.0 class-B

255.255.255.0 class-C

NOTE

If the value of the ipRouteDest is 0.0.0.0 (default route), then the mask value is also 0.0.0.0.

All IP routing subsystems implicitly use this mechanism.
