Configuring IP Services
10-6
Parameter: Apply Subnet Mask
Default: Null
Options: Null or IP address mask
Function: Specifies a mask that will override the interface’s subnet mask in the
presence of networks with variable-length subnet masks.
Instructions: Supply a mask, set the Action parameter to Accept, and use the default
Network parameter (an empty list).
If you specify a mask of 0.0.0.0, the router determines which mask to
apply. For example, if the network in the update is a subnet of the same
network as the receiving interface, the router applies the mask of the
receiving interface. If the network in the update is a subnet of a different
natural network, the router applies the natural mask of that network.
MIB Object ID: 1.3.6.1.4.1.18.3.5.3.2.1.8.1.9

2. Click on Edit.
3. Edit those parameters that you want to change.
All RIP import route filter parameters are described in “RIP Import Route
