ScopeId

  • Base type Unsigned32

A Scope Identifier identifies an instance of a specific scope. The scope identifier MUST disambiguate identical address values. For link-local addresses, the scope identifier will typically be the interface index (ifIndex as defined in the IF-MIB) of the interface on which the address is configured. The scope identifier may contain the special value 0 which refers to the default scope. The default scope may be used in cases where the valid scope identifier is not known (e.g., a management application needs to write a site-local InetAddressIPv6 address without knowing the site identifier value). The default scope SHOULD NOT be used as an easy way out in cases where the scope identifier for a non-global IPv6 address is known.
