OSPFv2 Local RIB
12.4(15)T
With the OSPFv2 Local RIB feature, each OSPF protocol
instance has its own local Routing Information Base (RIB).
The OSPF local RIB serves as the primary state for OSPF
SPF route computation. The global RIB is not updated with
intermediate results during the SPF. Instead, the global RIB
is updated only when routes are added, deleted, or changed,
thereby reducing global RIB computation. This reduced
update activity may result in fewer dropped packets.
