Dear Authors,
The LS Referenced LS Type in E-intra-area-prefix LSA is either E-Router-LSA type (0xA021)  or E-Network-LSA (0xA022), but not regular Router LSA type (0x2001) or Network LSA Type ( 0x2002).
These values in header of E-intra-area-prefix LSA are not same as regular intra-area-prefix LSA's header.

Can you please confirm.

Yes - it is expected that OSPFv3 Extended LSA will be consistently originated within an area. I will make this clear in the next revision as this is different from the RFC 5340 Intra-area-prefix LSA.

Thanks,
Acee



Regards,
Veerendranath
