alaPimsmOldRegisterMessageSupport
Alcatel Pimsm Old Register Message Support
1.3.6.1.4.1.6486.800.1.2.1.10.6.1.1.1.12
Specifies the application of the checksum function on received Register messages in the PIM-SM domain. When set to oldCisco(2), the checksum for a register message is computed for the entire packet (i.e. includes data). When set to latest(1), the checksum is done only on the first 8 bytes of the packet. This variable is provided for interoperability reasons and may be required for Compatibility with older implementations of PIM-SM v2. This parameter must be set the same throughout the PIM-SM domain.
