(Reducing the the number of CIDR blocks is good because the larger the the blocks allocated, the smaller the routing tables in upstream routers become. )

can someone explain this please :(

why is it good to reduce the number of the blocks

Thank you

Yes by reducing the number of CIDR blocks is good because the larger the blocks allocated, the smaller the routing tables in upstream routers become. Here see the routing table should be smaller because if it's smaller then the bandwidth and CPU it utilizes will be much lesser.

For a router to index and search for the destination path it will be faster because the routing table is smaller. So it's always good to maintain the routing table as much as smaller.

So here CIDR means classless inter-domain routing. CIDR means its kind of method for Ip routing and address allocation. There is one concept called aggregation which means this can be used to reduce the size of the routing table. So then the routing will be much quicker. What aggregation does means bringing all the different IP of the same network into one single route IP

See the below image for more clarity.

So larger the block size of CIDR means there are fewer blocks means more blocks are being aggregated and bring down as lesser number with large block size.

So this is why having larger CIDR blocks will reduce the size of routing table.

The maintenance department has fixed costs of $500,000 and variable costs of $30 per hour of maintenance provided. The variable costs include the salaries of the maintenance workers. More maintenance workers can be added if greater maintenance is demanded by the other departments without affecting the fixed costs of the maintenance department.
