### Description

```asn1
isisRASNPAMask OBJECT-TYPE
SYNTAX IsisOSINSAddress
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"A bit mask with 1 bits indicating the positions in the effective destination address from which embedded SNPA information is to be extracted. For the extraction, the first octet of the isisRASNPAMask object value is aligned with the first octet (AFI) of the NSAP Address. If the isisRASNPAMask object value and NSAP Address are of different lengths, the shorter of the two is logically padded with zeros before performing the extraction. This object follows the ManualOrAutomatic behavior."
REFERENCE "{ISIS.aoi sNPAMask (122)}"
DEFVAL { '00'H }
```

**Classification:** MIB object for network management
