Ipv6 summarization

This topic isn't covered in any depth in Odom and I couldn't find any decent examples on CCO. If anyone knows any links to some examples of Ipv6 summarization that would be great.

Dont know what you need, if you can do ipv4 summarization you should be able to do ipv6, just need to do more messing with binary.

c0a8:1600:12ab:8756::/64
c0a8:1600:12a4:7890::/64
c0a8:1600:12a6:ecf5::/64

In this case you can see the first 44 bits are the same, now you need to check bits 45 ->48.

b = 1011
4 = 0100
6 = 0110

Since you cant get a better match the best is /44.

Summary is c0a8:1600:12a0::/44

You cleared things up nicely right there Ed. Thanks a lot.

Wow, I am about to learn what all of this means.
