The bit mask of source protocols from which routes are imported to OSPFv3. Bit 1, if set, indicates that local routes are redistributed into OSPFv3. (value = 2) if reset, indicates that local routes are not redistributed into OSPFv3. Bit 2, if set, indicates that static routes are redistributed into OSPFv3. (value = 4) if reset, indicates that static routes are not redistributed into OSPFv3. Bit 4, if set, indicates that routes from RIP are redistributed into OSPFv3. (value = 16) if reset, indicates that routes from RIP are not redistributed into OSPFv3. Bit 6, if set, indicates that routes from BGP are redistributed into OSPFv3. (value = 64) if reset, indicates that routes from BGP are not redistributed into OSPFv3. Other bits are reserved for future use.
