Hello team,

Can someone verify if my method of calculating summary route is correct. Or how would you do it.

Here it goes.. I have the following subnets. and I need to do a summaray route on the router.

172.16.0.0

172.16.1.0

172.16.3.0

172.16.4.0

172.16.6.0

172.16.7.0

172.16.8.0

172.16.9.0

172.16.10.0

172.16.12.0

172.16.13.0

So to summary this route. I come up with 172.16.0.0/20. Here how I come up with that.

I take the last(biggest subnet) 172.16.13.0 (I need 4 bits for 13)

11111111.11111111.11110000.00000000

so 8+8+4 = 20

My assumption is 172.16.0.0/20 will summarize the given subnets.

Is there another easy way to calculate summary route for subnet ranges?

Thanks,

HN
