Proposed Enhancements Non-ackable LSAs for periodic flooding For LSAs that are updated frequently due to topology changes. Each DR periodically retransmits each non-ackable LSA as a multicast (until a new instance is received). Non-ackable LSAs are never ACKed or retransmitted as a unicast. Multicast retransmitted LSAs Avoids separate unicast retransmissions to several neighbors. Includes a list of neighbors that must ACK the LSA. Optimized database exchange. Only the master needs to include all LSA headers in DD packets. After receiving DD packets from the master, the slave only sends LSA headers that the master does not have. |
