Dear Authors,

In OSPFv2:
I am requesting for your clarification regarding  change in Opaque Type 7 and Opaque Type 8 LSAs (LSA origination/flush or modify)  need to consider for OSPFv2 GR exit case or not.
As per my understanding these LSAs will not be topology LSAs for OSPF, so it may not require to consider these LSAs for GR case.
I am requesting for your confirmation.

Also in OSPFv3:
SR information is carried in new extension LSAs, which can carry both topology and attribute information.
In this case, whether we need to consider LSA change for Graceful restart or not.
I am requesting for your confirmation.

Regards,
Veerendranath
