atmIfVptUniAddrPnniInfoScope
atm If Vpt Uni Address Pnni Info Scope
This attribute specifies the scope of the ATM address, which is the highest level up to which this address will be advertised in the PNNI hierarchy. The scope must be set to a value numerically less than or equal to the level of the lowest level peer group containing this node. Setting the scope to 0 will cause the address to be advertised globally within this PNNI routing domain.
