An advisory lock used to allow cooperating SNMP managers to coordinate their use of the set operation in creating or modifying rows within this table.

In order to use this lock to coordinate the use of set operations, managers should first retrieve ipv6RouterAdvertSpinLock. They should then determine the appropriate row to create or modify. Finally, they should issue the appropriate set command including the retrieved value of ipv6RouterAdvertSpinLock. If another manager has altered the table in the meantime, then the value of ipv6RouterAdvertSpinLock will have changed and the creation will fail as it will be specifying an incorrect value for ipv6RouterAdvertSpinLock. It is suggested, but not required, that the ipv6RouterAdvertSpinLock be the first var bind for each set of objects representing a 'row' in a PDU.
