Symptom: IPv6 Stateless Address Autoconfiguration (SLAAC) fails for hosts connected to the router via Bundle-Ether interfaces and Bundle-Ether sub-interfaces. Conditions: The prefixes in IPv6 Router Advertisements sent on Bundle-Ether interfaces and Bundle-Ether sub-interfaces are advertised with a prefix length of 128 bits regardless of the prefix length that is configured. This prevents hosts connected via these interface types from automatically configuring an IPv6 address using SLAAC. This issue is specific to Bundle-Ether interfaces and Bundle-Ether sub-interfaces.
