What is isisSysL2toL1Leaking?

Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.138.1.1.1.9 snmpwalk -v2c -c public <target> ISIS-MIB::isisSysL2toL1Leaking
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.138.1.1.1.9.1 snmpget -v2c -c public <target> ISIS-MIB::isisSysL2toL1Leaking.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.138.1.1.1.9.1 s <value>
