ipMultiPathMask
Module: ACC-MIB
OID (symbolic): ACC-MIB::ipMultiPathMask
OID (numeric): 1.3.6.1.4.1.5.1.1.23.1.4
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description:
Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the ipMultiPathDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the ipMultiPathMask by determining whether the value of the correspondent ipMultiPathDest 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 ipMultiPathDest 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 rout- ing subsystems implicitly use this mechanism.
What is ipMultiPathMask?
This OID defines the subnet mask (as an IP address like 255.255.255.0) that is ANDed with the destination address before comparing to ipMultiPathDest. Network engineers use this to support arbitrary subnet masks instead of just Class A/B/C boundaries, enabling flexible routing policies. Setting this to 255.255.0.0 matches entire /16 networks, while 255.255.255.0 matches specific /24 subnets.
