Changes since IETF 66
Draft clarifies that the additional step must be performed for every LSA listed in the received DD packet (to fully update the summary list) before the next DD packet is sent in response.
For faster lookup of LSAs in the summary list, the draft suggests that LSAs be listed in lexicographically increasing order of (LS type, Link State ID, Advertising Router) for OSPFv2 and (LS type, Advertising Router, Link State ID) for OSPFv3.
