ipForwardMask

Module: IP-FORWARD-MIB

OID (symbolic): IP-FORWARD-MIB::ipForwardMask

OID (numeric): 1.3.6.1.2.1.4.24.2.1.2

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-create

Description: Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the ipForwardDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the ipForwardMask by reference to the IP Address Class.

Any assignment (implicit or otherwise) of an instance of this object to a value x must be rejected if the bitwise logical-AND of x with the value of the corresponding instance of the ipForwardDest object is not equal to ipForwardDest.

What is ipForwardMask?

Obsolete subnet mask applied to the destination address in the original ipForwardTable; systems without arbitrary subnet masking derived this from the address's IP class, superseded by inetCidrRoutePfxLen.
