for full version visit http://www.nhanced.co.uk/free . In large internetworks thousands of network addresses can exist. It is often problematic for routers to maintain this volume of routes in their routing tables. By learning Route summarization you can reduce the number of routes to ensure your network runs faster

the link to the free courses takes your email address but does not link to any videos. Looks like a spam scam.

MyWay Lets take as an example the range of IPs 172.16.128.0-172.16.159.255 We see that the network mask will have to affect 3rd octet. The easy way it to subtract 128 from 159. Lets see 159-128=31 Now subtract 31 from 255 255-31=224 There we go, this is our 3rd octet in the subnet mask 172.16.128.0 255.255.224.0 Another example Summarize networks 100.16.0.0 100.17.0.0 100.18.0.0 100.19.0.0 19-16=3 255-3=252 Our subnet mask is 255.252.0.0 for network 100.16.0.0
