ipRouteMask
RFC1213-MIB ·
.1.3.6.1.2.1.4.21.1.11
Object
Indicate 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:
mask network
255.0.0.0 class-A
255.255.0.0 class-B
255.255.255.0 class-C
If the value of the ipRouteDest is 0.0.0.0 (a
default route), then the mask value is also
0.0.0.0. It should be noted that all IP routing
subsystems implicitly use this mechanism.
