VLSM

Hi,

I have a confusion with regard to VLSM. I have read, during my degree, that in order to do VLSM, we should start from the top (i.e. the highest number of hosts required). However,i have also seen cases (Cisco Dumps particularly), where they have started from the bottom (i.e. the lowest number of hosts required).

I am wondering what is the best approach?

Regards

Re: VLSM

The best approach when working with VLSM and I'm sure others will agree, start with the subnet that the requirement states - largest number of hosts.

Following this method helps prevent wasting addresses. Have ago your self and use VLSM in both directions, you will see the difference.

Re: VLSM

Hi,

It really depend upon you on what you'll be using if it's from lowest or largest but for me it's much more easier when you assign the largest first.

Thanks,

Allen

Re: VLSM

Yep, largest first.
