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

if any link fail in ospf network , it send link state
advertisement (LSA) packets with a sequence number to there
neighbor ,The neighbor check the failed link sequence
number with the sequence number of his link database, if
the advertised sequence number is high then the neighbor
sequence number , the neighbor update his database,,if low
it send his link related information to advertiser,,if
equal it simply discard the packet.......Through this way
convergence happen in ospf.....

How does the cut-through switching technique work? A.) By using broadcast address as source addresses B.) The switch waits only for the header to be received before it checks the destination address and starts forwarding the packets C.) The LAN switch copies the entire frame into its onboard buffers and then looks up the destination address in its forwarding, or switching, table and determines the outgoing interface D.) By using a Class I repeater in a collision domain
