| Is There a Formula for Determine Routing Summarized addresses???
Given a Network(172.16.0.0) with Subents of Given Network(172.16.1.192/28, 172.16.1.208/28 ETC) How do you determine the subnets that can be sumarized and what the formula for determining the summarized addresses...

Depends entirely on how you've laid out your addresses and where in the network you're summarizing. The two subnets you mention can, of course, be summarized as 172.16.1.192/27.

| you have to see the least common bits .Just write down 192 & 208 in bits format you will understand by yourself | |

| The pitfall of route summarization (route aggregation) is that you must own the block of addresses in that range you specify. I noticed you had a comma separating your two class B subnets and not a dash which usually represents hierarchical range. |
