  "message": "ospf: suppress delete using replacement\n\nAfter a SPF run, OSPF deletes routes that have changed in terms of any\nmetric, type, and/or next-hops and re-adds them. Given that the Zebra-RIB\nalready support replacement semantics, we suppress deletes for routes\nthat will be added back again.\n\nThis has the following advantages. It reduces the number of IPC messages\nbetween OSPF/Zebra. Also, in the current flow, a batch of route deletes\nwere followed by a batch of adds even for say a metric change.\n\nWith the change, routes are sent as \"add\" when they are modified. Zebra\nalready implicitly deletes older routes.\n\nSigned-off-by: Ayan Banerjee \u003cayan@cumulusnetworks.com\u003e\nReviewed-by: Scott Feldman \u003csfeldma@cumulusnetworks.com\u003e\nReviewed-by: Dinesh Dutt \u003cddutt@cumulusnetworks.com\u003e\nSigned-off-by: Scott Feldman \u003csfeldma@cumulusnetworks.com\u003e\n",
