How convergence happen in ospf?..

Answer / jitendera

convergence-when ther is nay change in network the
convergence proccess ocuurs.
When a route table or routing database becomes too large
(causing delays in packet processing), Route summarization
and stub areas are options to improve performance. There
are two types of route summarization: inter-areas and
external. ABR [Area Border Routers] summarize stub routes
and ASBR [Autonomous System Boundary Routers] summarize
only external routes.

Let’s see how convergence is reached in a network that
includes stub and totally stub routers.

Another route summarization tool is to create stub areas
and totally stub/stubby Areas. ABRs create sub-networks.
The stub/totally stub areas only communicate to the ABR via
default route 0.0.0.0. This means the stub/totally stub
router does not have a route to the destination; it just
forwards packets to the ABR which will forward the packet
to the destination. However, Stub routers contain all route
tables, whereas a totally stub knows only the routes within
its area
