Hello support community,
I'm trying to write a summary network address for the ip address in red below, but they need to be separate from the ones in black, is this a proper summary route for these networks in red? 10.20.0.0/10 ?
IP Address | Binary 1st octet | Binary 2st octet | Binary 3rd octet | Binary 4th octet |

What about the subnet mask? Are all this /24?
07-18-2014 02:11 AM
Hi,
I think you need to split aggregation in to below three subnets.
10.16.0.0/12
10.32.0.0/11
10.64.0.0/10
10.20.0.0/10 is not a valid prefix.

Hi Akash,
correct, but
10.64.0.0/12
would be enough.
Bets regards,

Hi Milan,
Would 10.64.0.0/12 cover 10.20.0.0? I don't think so, i will cover 10.64.0.0 to 10.79.0.0 if i consider only 2nd octet.

Hi,
sorry, I should have been clearer:
10.64.0.0/12 should be enough instead 10.64.0.0/10.
So
10.16.0.0/12
10.32.0.0/11
10.64.0.0/12
is the complete solution.
Best regards,
Milan

Hello
I have it as this:
10.0.0.0/14
10.20.0.0/16
10.30.0.0/15
10.32.0.0/11
10.64.0.0/12

I actually have a totally different result, the ip addresses in black 10.0.0.0, 10.2.0.0, and 10.3.0.0 will be separate from the red ip addresses in red. it would basically be all /12 so I can keep those summary separated. look ok?
IP block 10.0.0.0/12 - range 10.0.0.1 - 10.15.255.254
IP block 10.20.0.0/12 - range 10.16.0.1 - 10.31.255.254
IP block 10.32.0.0/12 - range 10.32.0.1 - 10.47.255.254
IP block 10.48.0.0/12 - range 10.48.0.1 - 10.63.255.254
IP block 10.70.0.0/12 - range 10.64.0.1 - 10.79.255.254
Thanks,

Hello
You original query was to summarise on the subnets you posted , hence the specific summarization.
If you mean to include the other subnets not shown then a more generic addressing would also be applicable.

I ended up using /12 which is a block of 16 subnets for my summary, it accomplished the goal. .
10.0.0.0/12
10.16.0.0/12
10.32.0.0/12
10.48.0.0/12
10.64.0.0/12
Thanks everyone for helping with this.
