This version includes the following additions:
1. Added IPv4 Forwarding Address sub-TLV
2. Added restriction that OSPFv3 Extended LSA must include the required TLVs
or be considered malformed.
- E-Inter-Area-Prefix-LSA must include the Inter-Area-Prefix TLV
- E-Inter-Area-Router-LSA must include the Inter-Area-Router TLV
- E-AS-External-LSA must include the External-Prefix TLV
- E-NSSA-LSA must include the External-Prefix TLV
- E-Link-LSA must in either the IPv6-Link-Local-Address TLV or the
IPv4-Link-Local-Address TLV.
Also, considered whether we should require at least 1 link in the
E-Router-LSA and at least one prefix in the E-Inra-Area-Prefix-LSA but decided
against it.
3. Added a section on the recommended handling for malformed OSPFv3 extended
LSAs.
4. Added a statement on graceful restart handling to the compatibility
section.
Thanks,
Acee
