### Description

```asn1
docsBpiIpMulticastPrefixLength OBJECT-TYPE
SYNTAX Integer32 (0..32)
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This object represents the IP multicast address prefix length
for this row. The value of this object represents the length in
bits of docsBpiIpMulticastAddress for multicast address
comparisons, using big-endian ordering. An IP multicast address
matches this row if the (docsBpiIpMulticastPrefixLength) most
significant bits of the IP multicast address and of the
(docsBpiIpMulticastAddress) are identical.
This object is similar in usage to an IP address mask. The value
0 corresponds to IP address mask 0.0.0.0, the value 1 corresponds
to IP address mask 128.0.0.0, the value 8 corresponds to IP
address mask 255.0.0.0, and the value 32 corresponds to IP
address mask 255.255.255.255."
